Zint Barcode Generator and Zint Barcode Studio User Manual
==========================================================
1. Introduction
===============
The Zint project aims to provide a complete cross-platform open source barcode
generating solution. The package currently consists of a Qt based GUI, a
command line executable and a library with an API to allow developers access to
the capabilities of Zint. It is hoped that Zint provides a solution which is
flexible enough for professional users while at the same time takes care of as
much of the processing as possible to allow easy translation from input data to
barcode image.
The library which forms the main component of the Zint project is currently
able to encode data in over 50 barcode symbologies (types of barcode), for each
of which it is possible to translate that data from either Unicode (UTF-8) or a
raw 8-bit data stream. The image can be rendered as either a Portable Network
Graphic (PNG) image, Windows Bitmap (BMP), Graphics Interchange Format (GIF),
ZSoft Paintbrush image (PCX), as Encapsulated Post Script (EPS) or as a
Scalable Vector Graphic (SVG). Many options are available for setting the
characteristics of the output image including the size and colour of the image,
the amount of error correction used in the symbol and, in the case of raster
images, the orientation of the image.
1.1 Terms of Reference
----------------------
Some of the words and phrases used in this document are specific to barcoding,
and so a brief explanation is given to help understanding:
symbol: A symbol is an image which encodes data according to one of the
standards. This encompases barcodes (linear symbols) as well as any of
the other methods of representing data used in this program.
symbology: A method of encoding data to create a certain type of symbol.
linear: A linear symbol is one which consists of bars and spaces, and is what
most people associate with the term "barcode". Examples include EAN.
stacked: A stacked symbol consists of multiple linear symbols placed one above
another and which together hold the message, usually allong side some
error correction data. Examples include PDF417.
matrix: A matrix symbol is one based on a (usually square) grid of elements.
Examples include Data Matrix, but Maxicode and DotCode are also
considered matrix symbologies.
x-dimension: The x-dimension of a symbol is size (usually the width) of the
smallest element. For a linear symbology this is the width of the
smallest bar. The default size of the x-dimension in a raster image
is 2 pixels. Many symbologies have a fixed width-to-height ratio where
the height is expressed as a multiple of the x-dimension.
composite: A composite symbology is one which is made up of elements which are
both linear and stacked. Those currently supported are made up of a
linear "primary" message above which is printed a stacked component
based on the PDF417 symbology. These symbols also have a separator
which seperates the linear and the stacked components.
GS-1 data: This is a structured way of representing information which consists
of "chunks" of data, each of which starts with an Application
Identifier. The AI identifies what type of information is being
encoded. See Appendix C.
Reader Initialisation: Some symbologies allow a special character to be included
which can be detected by the scanning equipment as signifying that the
data is used to program or change settings in that equipment. This data
is usually not passed on to the software which handles normal input
data. This feature should only be used if you are familiar with the
programming codes relevant to your scanner.
ECI: The ECI mechanism allows for multi-language data to be encoded in
symbols which would usually support only Latin-1 characters. This can
be useful, for example, if you need to encode cyrillic characters, but
should be used with caution as not all scanners support this method.
2. Installing Zint
==================
2.1 Linux
---------
The easiest way to configure compilation is to take advantage of the CMake
utilities. You will need to install CMake and libpng first. Note that you will
need both libpng and libpng-devel packages. If you want to take advantage of
Zint Barcode Studio you will also need the Qt libraries pre-installed.
Once you have fulfilled these requirements unzip the source code tarball and
follow these steps in the top directory:
mkdir build
cd build
cmake ..
make
make install
The command line program can be accessed by typing
zint {options} -d {data}
Notice that the data needs to be entered after all other options. Any options
given after the data will be ignored. The GUI can be accessed by typing
zint-qt
To test that the installation has been successful a shell script is included in
the /frontend folder. To run the test type
./test.sh
This should create numerous files showing the many modes of operation which are
available from Zint.
2.2 Microsoft Windows
---------------------
To run Zint Barcode Studio on Windows simply download and run the installation
executable and follow the instructions on-screen.
2.3 Apple macOS
---------------
Zint can be compiled on macOS from the command line using the same steps as shown
for Linux above. Currently the Zint Barcode Studio GUI is not known to work on
macOS. The Zint developers do not currently have access to Apple hardware and
so are not able to provide support or binaries for macOS. If you are a macOS
developer, however, or if you have any success in building Zint on macOS, we
would love to hear from you.
2.4 zint tcl backend
--------------------
The tcl backend may be build using the provided TEA build on Linux, Windows,
Mac-OS and Android. For Windows, a MS-VC6 makefile is also available.
3. Using Zint Barcode Studio
============================
Zint Barcode Studio is the graphical user interface for Zint. If you are
starting from a command line interface you can start the GUI by typing
zint-qt
or in Windows
zint-qt.exe
(The rest of this section of the manual involves use of the GUI, so has been
removed from this text-only version)
4. Using the Command Line
=========================
This section describes how to encode data using the command line front end
program. The examples given are for the Linux platform, but the same options
are available for Windows - just rememer to include the executable file
extension. i.e.:
zint.exe -d "This Text"
4.1 Inputting data
------------------
The data to encode can be entered at the command line using the -d option, for
example
zint -d "This Text"
This will encode the text "This Text". Zint will use the default symbology,
Code 128, and output to the default file out.png in the current directory.
Alternatively, if libpng was not present when Zint was built, the default
output file will be out.gif. The -d switch and the input data should always
be the last entry on the command line input. Any options given after this
will be ignored.
The data input to Zint is assumed to be encoded in Unicode (UTF-8) format. If
you are encoding characters beyond the 7-bit ASCII set using a scheme other than
Unicode then you will need to set the appropriate input options as shown in
section 4.11 below.
Non-printing characters can be entered on the command line using the backslash
(\) as an escape character. Permissible characters are shown in the table
below. Note that this only applies on the command line.
-------------------------------------------------------------
Escape Character | ASCII Equivalent | Interpretation
-------------------------------------------------------------
\0 | 0x00 | Null
\E | 0x04 | End of Transmission
\a | 0x07 | Bell
\b | 0x08 | Backspace
\t | 0x09 | Horizontal Tab
\n | 0x0A | Line Feed
\v | 0x0B | Vertical Tab
\f | 0x0C | Form Feed
\r | 0x0D | Carriage Return
\e | 0x1B | Escape
\G | 0x1D | Group Selector
\R | 0x1E | Record Selector
-------------------------------------------------------------
Input data can be read directly from file using the -i switch as shown below.
The input file is assumed to be Unicode (UTF-8) formatted unless an alternative
mode is selected. This command replaces the use of the -d switch and should
similarly be the last option given.
zint -i ./somefile.txt
4.2 Directing Output
--------------------
Output can be directed to a file other than the default using the -o switch.
For example:
zint -o here.png -d "This Text"
This draws a Code 128 barcode in the file here.png. If an encapsulated Post Script
file is needed simply append the file name with .eps, and so on for the other
supported file types:
zint -o there.eps -d "This Text"
4.3 Selecting barcode type
--------------------------
Selecting which type of barcode you wish to produce (i.e. which symbology to
use) can be done at the command line using the -b or --barcode= switch followed
by the appropriate integer value in the following table. For example to create
a Data Matrix symbol you could use:
zint -o datamatrix.png -b 71 -d "Data to encode"

--------------------------------------------------------------------------------
4.4 Adjusting height
--------------------
The height of a linear symbol can be adjusted using the --height switch. For
example:
zint --height=100 -d "This Text"
This specifies a symbol height of 100 times the x-resolution of the symbol.
4.5 Adjusting whitespace
------------------------
The amount of whitespace to the left and right of the generated barcode can be
altered using the –w switch. For example:
zint -w 10 -d "This Text"
This specifies a whitespace width of 10 times the x-resolution of the symbol.
4.6 Adding boundary bars and boxes
----------------------------------
Zint allows the symbol to be bound with 'boundary bars' using the option
--bind. These bars help to prevent misreading of the symbol by corrupting a
scan if the scanning beam strays off the top or bottom of the symbol. Zint can
also put a border right around the symbol and its whitespace with the --box
option. This option is automatically selected for ITF-14 symbols.
The width of the boundary or box can be specified using the --border switch.
For example:
zint --box --border=10 -d "This"
gives a box with a width 10 times the x-resolution of the symbol.
4.7 Using colour
----------------
The default colours of a symbol are a black symbol on a white background. Zint
allows you to change this. The -r switch allows the default colours to be
inverted so that a white symbol is shown on a black background. For example the
command
zint -r -d "This"
gives an inverted Code 128 symbol. This is not practical for most symbologies
but white-on-black is allowed by the Data Matrix ECC200 and Aztec Code
symbology specifications.
For more specific needs the foreground (ink) and background (paper) colours
can be specified using the --fg= and --bg= options followed by a number in RRGGBB
hexadecimal notation (the same system used in HTML). For example the command
zint --fg=004700 -d "This"
alters the symbol to a dark green.
4.8 Rotating the Symbol
-----------------------
The symbol can be rotated through four orientations using the --rotate= option
followed by the angle of rotation as shown below. This option is only available
with raster image (PNG, BMP, GIF and PCX) output.
--rotate=0 (default)
--rotate=90
--rotate=180
--rotate=270
4.9 Adjusting image size
------------------------
The scale of the image can be altered using the --scale= option followed by a
multiple of the default x-dimension. The default x-dimension is 2 pixels. For
example for PNG images a scale of 5 will increase the x-dimension to 10 pixels.
4.10 Input modes
----------------
By default all input data is assumed to be encoded in Unicode (UTF-8) format.
Many barcode symbologies encode data using Latin-1 (ISO-8851-1) character
encoding, so input is converted from Unicode to Latin-1 before being put in the
symbol. In addition QR Code, Micro QR Code, Han Xin Code and Grid Matrix
standards can encode Chinese or Japanese characters which are also converted
from Unicode. If Zint encounters characters which can not be encoded using the
default character encoding then it will take advantage of the ECI (Extended
Channel Interpretations) mechanism to encode the data. Be aware that not all
barcode readers support ECI mode, so this can sometimes lead to unreadable
barcodes. If you are using characters beyond those supported by Latin-1 then
you should check that the resulting barcode can be understood by your target
barcode reader. Zint will generate a warning message when ECI codes have been
inserted into a symbol.
GS1 data can be encoded in a number of symbologies. Application identifiers
should be enclosed in [square brackets] followed by the data to be encoded (see
5.1.12.3). To encode GS1 data use the --gs1 option. GS1 mode is assumed (and
doesn't need to be set) for EAN-128, DataBar and Composite symbologies but is
also available for Code 16k, Data Matrix, Aztec Code, DotCode and QR Code.
HIBC data may also be encoded in the symbologies Code 39, Code128, Codablock-F,
Datamatrix, QR-Code, PDF417 and Aztec-Code. Within this mode, the leading '+' and the
check character is automatically added.
The --binary option prevents Zint from performing any convertion of the data
before placing in the barcode symbol and should be used if you are encoding raw
binary or encrypted data.
If your platform does not use Unicode or if you are using data from file which
is not stored in UTF-8 then you can specify the encoding by using the --binary
switch in combination with the --eci= switch followed by the appropriate number
from the table below. This procedure adds an ECI flag in the barcode data which
tells the barcode reader to change character encoding.
--------------------------------------------------------
ECI Code | Character Encoding Scheme
--------------------------------------------------------
3 | ISO-8859-1 - Latin alphabet No. 1 (default)
4 | ISO-8859-2 - Latin alphabet No. 2
5 | ISO-8859-3 - Latin alphabet No. 3
6 | ISO-8859-4 - Latin alphabet No. 4
7 | ISO-8859-5 - Latin/Cyrillic alphabet
8 | ISO-8859-6 - Latin/Arabic alphabet
9 | ISO-8859-7 - Latin/Greek alphabet
10 | ISO-8859-8 - Latin/Hebrew alphabet
11 | ISO-8859-9 - Latin alphabet No. 5
12 | ISO-8859-10 - Latin alphabet No. 6
13 | ISO-8859-11 - Latin/Thai alphabet
15 | ISO-8859-13 - Latin alphabet No. 7
16 | ISO-8859-14 - Latin alphabet No. 8 (Celtic)
17 | ISO-8859-15 - Latin alphabet No. 9
18 | ISO-8859-16 - Latin alphabet No. 10
21 | Windows-1250 - Latin 2 (Central Europe)
22 | Windows-1251 - Cyrillic
23 | Windows-1252 - Latin 1
24 | Windows-1256 - Arabic
26 | Unicode (UTF-8)
--------------------------------------------------------
4.11 Batch processing
---------------------
Data can be batch processed by reading from a text file and producing a
separate barcode image for each line of text in that file. To do this use the
--batch switch. To select the input file from which to read data use the –i
option. Zint will automatically detect the end of a line of text (in either
Unix or Windows formatted text files) and produce a symbol each time it finds
this. Input files should end with a return character – if this is not present
then Zint will not encode the last line of text, and will warn you that there
is a problem.
By default Zint will output numbered filenames starting with 00001.png,
00002.png etc. To change this behaviour use the –o option in combination with
--batch using special characters in the output file name as shown in the table
below:
---------------------------------------------
Input Character | Interpretation
---------------------------------------------
~ | Insert a number or '0'
# | Insert a number or space
@ | Insert a number or "*"
Any other | Insert literally
---------------------------------------------
The following table shows some examples to clarify this method:
--------------------------------------------------------------
Input | Filenames Generated
--------------------------------------------------------------
-o file~~~.svg | file001.svg, file002.svg, file003.svg
-o @@@@bar.png | ***1.png, ***2.png, ***3.png
-o my~~~bar.eps | my001.bar.eps, my002.bar.eps, my003bar.eps
-o t@es~t~.png | t*es0t1.png, t*es0t2.png, t*es0t3.png
--------------------------------------------------------------
4.12 Direct output
------------------
The finished image files can be output directly to stdout for use as part of
a pipe by using the --direct option. By default --direct will output data
as a PNG image, but this can be altered by supplimenting the --direct option
with a --filetype= option followed by the suffix of the file type required.
For example:
zint -b 84 --direct --filetype=pcx -d "Data to encode"
This command will output the symbol as a PCX file to stdout. The currently
supported output file formats are shown in the following table:
--------------------------------------------------------------
Abbreviation | File format
--------------------------------------------------------------
BMP | Windows Bitmap
EPS | Encapsulated PostScript
GIF | Graphics Interchange Format
PCX | ZSoft Paintbrush image
PNG | Portable Network Graphic
SVG | Scalable Vector Graphic
TXT | Text file (see 4.16)
--------------------------------------------------------------
=============================================================================
CAUTION: Outputting binary files to the command shell without catching that
data in a pipe can have unpredictable results. Use with care!
=============================================================================
4.13 Automatic filenames
------------------------
The --mirror option instructs Zint to use the data to be encoded as an
indicator of the filename to be used. This is particularly useful if you are
processing batch data. For example the input data "1234567" will result in
a file named 1234567.png.
There are restrictions, however, on what characters can be stored in a file
name, so the file name may vary from the data if the data includes non-
printable characters, for example, and may be shortened if the data input is
long.
To set the output file format use the --filetype= option as detailed in
section 4.12.
4.14 Working with dots
----------------------
Matrix codes can be rendered as a series of dots or circles rather than the
normal squares by using the --dotty option. This option is only available for
matrix symbologies, and is automatically selected for DotCode. The size of
the dots can be adjusted using the --dotsize= option followed by the radius
of the dot, where that radius is given as a multiple of the x-dimension.
4.15 Help options
-----------------
There are three help options which give information about how to use the
command line. The -h or --help option will display a list of all of the valid
options available, and also gives the exact version of the software.
The -t or --types option gives the table of symbologies along with the symbol
ID numbers.
The -e or --ecinos option gives a list of the ECI codes supported by Zint.
4.16 Other output options
-------------------------
For linear barcodes the text present in the output image can be removed by
using the --notext option.
The text can be set to bold using the --bold option, or a smaller font
can be substituted using the --small option. The --bold and --small options
can be used together if required.
Zint can output a representation of the symbol data as a set of hexadecimal
values if asked to output to a text file (*.txt) or if given the option
--filetype=txt. This can be used for test and diagnostic purposes.
The --cmyk option is specific to output in encapsulated PostScript, and
converts the RGB colours used to the CMYK colour space. Setting custom
colours at the command line will still need to be done in RRGGBB format.
Additional options are available which are specific to certain symbologies.
These may, for example, control the amount of error correction data or the
size of the symbol. These options are discussed in section 6 of this guide.
5. Using the API
================
Zint has been written using the C language and currently only has an API for
use with C language programs. A wrapper is available for Pascal/Delphi
developers thanks to theunknownones from
http://theunknownones.googlecode.com/svn/trunk/Components/ZintBarcode/.
This wrapper, however, is likely to be out of date and may not function as
expected.
The libzint API has been designed to be very similar to that used by the GNU
Barcode package. This allows easy migration from GNU Barcode to Zint. Zint,
however, uses none of the same function names or option names as GNU Barcode.
This allows you to use both packages in your application without conflict if
you wish.
5.1 Creating and Deleting Symbols
---------------------------------
The symbols manipulated by Zint are held in a zint_symbol structure defined in
zint.h. These symbols are created with the ZBarcode_Create() function and
deleted using the ZBarcode_Delete() function. For example the following code
creates and then deletes a symbol:
#include <stdio.h>
#include <zint.h>
int main()
{
struct zint_symbol *my_symbol;my_symbol = ZBarcode_Create();
if(my_symbol != NULL)
{
printf("Symbol successfully created!\n");
}
ZBarcode_Delete(my_symbol);
return 0;
}
When compiling this code it will need to be linked with the libzint library
using the -lzint option:
gcc -o simple simple.c –lzint
5.2 Encoding and Saving to File
-------------------------------
To encode data in a barcode use the ZBarcode_Encode() function. To write the
symbol to a file use the ZBarcode_Print() function. For example the following
code takes a string from the command line and outputs a Code 128 symbol in a
PNG file named out.png (or a GIF file called out.gif if libpng is not present)
in the current working directory:
#include <stdio.h>
#include <zint.h>
int main(int argc, char **argv)
{
struct zint_symbol *my_symbol;
my_symbol = ZBarcode_Create();
ZBarcode_Encode(my_symbol, argv[1], 0);
ZBarcode_Print(my_symbol, 0);
ZBarcode_Delete(my_symbol);
return 0;
}
This can also be done in one stage using the ZBarcode_Encode_and_Print()
function as shown in the next example:
#include <stdio.h>
#include <zint.h>
int main(int argc, char **argv)
{
struct zint_symbol *my_symbol;
my_symbol = ZBarcode_Create();
ZBarcode_Encode_and_Print(my_symbol, argv[1], 0, 0);
ZBarcode_Delete(my_symbol);
return 0;
}
Input data should be Unicode (UTF-8) formatted.
5.3 Encoding and Printing Functions in Depth
--------------------------------------------
The functions for encoding and printing barcodes are defined as:
int ZBarcode_Encode(struct zint_symbol *symbol, unsigned char *input, int
length);
int ZBarcode_Encode_File(struct zint_symbol *symbol, char *filename);
int ZBarcode_Print(struct zint_symbol *symbol, int rotate_angle);
int ZBarcode_Encode_and_Print(struct zint_symbol *symbol, unsigned char *input,
int length, int rotate_angle);
int ZBarcode_Encode_File_and_Print(struct zint_symbol *symbol, char *filename,
int rotate_angle);
In these definitions "length" can be used to set the length of the input
string. This allows the encoding of NULL (ASCII 0) characters in those
symbologies which allow this. A value of 0 will disable this function and Zint
will encode data up to the first NULL character in the input string.
The "rotate_angle" value can be used to rotate the image when outputting as a
raster image. Valid values are 0, 90, 180 and 270.
The ZBarcode_Encode_File() and ZBarcode_Encode_File_and_Print() functions can
be used to encode data read directly from a text file where the filename is given
in the "filename" string.
5.4 Buffering Symbols in Memory
-------------------------------
In addition to saving barcode images to file Zint allows you to access a
representation of the resulting bitmap image in memory. The following functions
allow you to do this:
int ZBarcode_Buffer(struct zint_symbol *symbol, int rotate_angle);
int ZBarcide_Encode_and_Buffer(struct zint_symbol *symbol, unsigned char
*input, int length, int rotate_angle);
int ZBarcode_Encode_File_and_Buffer(struct zint_symbol *symbol, char *filename,
int rotate_angle);
The arguments here are the same as above. The difference is that instead of
saving the image to file it is placed in a character array. The "bitmap"
pointer is set to the first memory location in the array and the values
"barcode_width" and "barcode_height" indicate the size of the resulting image
in pixels. Rotation and colour options can be used at the same time as using
the buffer functions in the same way as when saving to a raster image. The
pixel data can be extracted from the character array by the methd shown in
the example below where render_pixel() is assumed to be a function for drawing
a pixel on the screen implemented by the external application:
int row, col, i = 0;
int red, blue, green;
for (row = 0; row < my_symbol->bitmap_height; row++) {
for (column = 0; column < my_symbol->bitmap_width; column++) {
red = my_symbol->bitmap[i];
green = my_symbol->bitmap[i + 1];
blue = my_symbol->bitmap[i + 2];
render_pixel(row, column, red, green, blue);
i += 3;
}
}
5.5 Setting Options
-------------------
So far our application is not very useful unless we plan to only make Code 128
symbols and we don't mind that they only save to out.png. As with the CLI
program, of course, these options can be altered. The way this is done is
by altering the contents of the zint_symbol structure between the creation and
encoding stages. The zint_symbol structure consists of the following variables:
-------------------------------------------------------------------------------
Variable Name | Type | Meaning | Default Value
-------------------------------------------------------------------------------
symbology | integer | Symbol to use (see section | BARCODE_CODE128
| | 5.7). |
height | integer | Symbol height. [1] | 50
whitespace_width | integer | Whtespace width. | 0
border_width | integer | Border width. | 0
output_options | integer | Set various output file | (none)
| | parameters (see section |
| | 5.8). [2] |
fgcolour | character | Foreground (ink) colour as | "000000"
| string | RGB hexadecimal string. |
| | Must be 6 characters |
| | followed by terminating |
| | \0 character. |
bgcolour | character | Background (paper) colour | "ffffff"
| string | as RGB hexadecimal |
| | string. Must be 6 chara- |
| | ters followed by termin- |
| | ating \0 character. |
outfile | character | Contains the name of the | "out.png"
| string | file to output a result- |
| | ing barcode symbol to. |
| | Must end in .png, .gif, |
| | .eps, .pcx, .svg or .txt |
option_1 | integer | Symbol specific options. | (automatic)
option_2 | integer | Symbol specific options. | (automatic)
option_3 | integer | Symbol specific options. | (automatic)
scale | float | Scale factor for adjusting | 1.0
| | size of image. |
input_mode | integer | Set encoding of input data | UNICODE_MODE
| | (see section 5.9) |
eci | integer | Extended Channel Interpre- | 3
| | tation mode. |
primary | character | Primary message data for | NULL
| string | more complex symbols. |
text | unsigned | Human readable text, which | NULL
| character | usually consists of in- |
| string | put data plus one more |
| | check digit. Uses UTF-8 |
| | formatting. |
show_hrt | integer | Set to 0 to hide text. | 1
dot_size | float | Size of dots used in dotty | 4.0 / 5.0
| | mode. |
rows | integer | Number of rows used by the | (output only)
| | the symbol. |
width | integer | Width of the generated sym- | (output only)
| | bol. |
encoding_data | array of | Representation of the | (output only)
| character | encoded data. |
| strings | |
row_height | array of | Representation of the | (output only)
| integers | height of a row. |
errtxt | character | Error message in the event | (output only)
| string | that an error ocurred. |
bitmap | pointer to | Pointer to stored bitmap | (output only)
| character | image. |
| array | |
bitmap_width | integer | Width of stored bitmap | (output only)
| | image (in pixels). |
bitmap_height | integer | Height of stored bitmap | (output only)
| | image (in pixels). |
-------------------------------------------------------------------------------
To alter these values use the syntax shown in the example below. This code has
the same result as the previous example except the output is now taller and
plotted in green.
#include <stdio.h>
#include <zint.h>
#include <string.h>
int main(int argc, char **argv)
{
struct zint_symbol *my_symbol;my_symbol = ZBarcode_Create();
strcpy(my_symbol->fgcolour, "00ff00");
my_symbol->height = 400;
ZBarcode_Encode_and_Print(my_symbol, argv[1], 0, 0);
ZBarcode_Delete(my_symbol);
return 0;
}
5.6 Handling Errors
-------------------
If errors occur during encoding an integer value is passed back to the calling
application. In addition the errtxt value is used to give a message detailing
the nature of the error. The errors generated by Zint are given in the table
below:
-------------------------------------------------------------------------------
Return Value | Meaning
-------------------------------------------------------------------------------
ZINT_WARN_INVALID_OPTION | One of the values in zint_struct was set
| incorrectly but Zint has made a guess at
| what it should have been and generated a
| barcode accordingly.
ZINT_WARN_USES_ECI | Zint has automatically inserted an ECI
| character. The symbol may not be readable
| with some readers.
ZINT_ERROR_TOO_LONG | The input data is too long or too short for the
| selected symbology. No symbol has been
| generated.
ZINT_ERROR_INVALID_DATA | The data to be encoded includes characters which
| are not permitted by the selected symbology
| (e.g. alphabetic characters in an EAN
| symbol). No symbol has been generated.
ZINT_ERROR_INVALID_CHECK | An ISBN with an incorrect check digit has been
| entered. No symbol has been generated.
ZINT_ERROR_INVALID_OPTION | One of the values in zint_struct was set
| incorrectly and Zint was unable to guess what
| it should have been. No symbol has been
| generated.
ZINT_ERROR_ENCODING_PROBLEM | A problem has occurred during encoding of the
| data. This should never happen. Please
| contact the developer if you encounter this
| error.
ZINT_ERROR_FILE_ACCESS | Zint was unable to open the requested output
| file. This is usually a file permissions
| problem.
ZINT_ERROR_MEMORY | Zint ran out of memory. This should only be a
| problem with legacy systems.
-------------------------------------------------------------------------------
To catch errors use an integer variable as shown in the code below:
#include <stdio.h>
#include <zint.h>
#include <string.h>
int main(int argc, char **argv)
{
struct zint_symbol *my_symbol;
int error = 0;
my_symbol = ZBarcode_Create();
strcpy(my_symbol->fgcolour, "nonsense");
error = ZBarcode_Encode_and_Print(my_symbol, argv[1], 0, 0);
if(error != 0)
{
/* some error occurred */
printf("%s\n", my_symbol->errtxt);
}
if(error > WARN_INVALID_OPTION)
{
/* stop now */
ZBarcode_Delete(my_symbol);
return 1;
}
/* otherwise carry on with the rest of the application */
ZBarcode_Delete(my_symbol);
return 0;
}
This code will exit with the appropriate message:
error: malformed foreground colour target

5.8 Adjusting other output options
----------------------------------
The output_options variable can be used to adjust various aspects of the output
file. To select more than one option from the table below simply add them together
when adjusting this value:
my_symbol->output_options += BARCODE_BIND + READER_INIT;
--------------------------------------------------------------------------------
Value | Effect
--------------------------------------------------------------------------------
0 | No options selected.
BARCODE_BIND | Boundary bars above and below the symbol and between
| rows if stacking multiple symbols. [2]
BARCODE_BOX | Add a box surrounding the symbol and whitespace. [2]
BARCODE_STDOUT | Output the file to stdout.
READER_INIT | Add a reader initialisation symbol to the data before
| encoding.
SMALL_TEXT | Use a smaller font for the human readable text.
BOLD_TEXT | Embolden the human readable text.
CMYK_COLOUR | Select the CMYK colour space option for encapsulated
| PostScript files.
BARCODE_DOTTY_MODE | Plot a matrix symbol using dots rather than squares.
--------------------------------------------------------------------------------
5.9 Setting the Input Mode
--------------------------
The way in which the input data is encoded can be set using the input_mode
property. Valid values are shown in the table below.
-----------------------------------------------------------------------------
Value | Effect
-----------------------------------------------------------------------------
DATA_MODE | Uses full ASCII range interpreted as Latin-1 or binary data.
UNICODE_MODE | Uses pre-formatted UTF-8 input.
GS1_MODE | Encodes GS1 data using FNC1 characters.
-----------------------------------------------------------------------------
5.10 Verifying Symbology Availability
-------------------------------------
An additional function available in the API is defined as:
int ZBarcode_ValidID(int symbol_id);
This function allows you to check whether a given symbology is available. A
non-zero return value indicates that the given symbology is available. For
example:
if(ZBarcode_ValidID(BARCODE_PDF417) != 0) {
printf("PDF417 available");
} else {
printf("PDF417 not available");
}
[1] This value is ignored for Australia Post 4-State Barcodes, PostNet, PLANET,
USPS OneCode, RM4SCC, PDF417, Data Matrix ECC200, Maxicode, QR Code, GS1
DataBar-14 Stacked, PDF417 and MicroPDF417 - all of which have a fixed height.
[2] This value is ignored for Code 16k, Codablock-F and ITF-14 symbols.
6. Types of Symbology
=====================
6.1 One-Dimensional Symbols
---------------------------
One-Dimensional Symbols are what most people associate with the term barcode.
They consist of a number of bars and a number of spaces of differing widths.
6.1.1 Code 11
-------------
Developed by Intermec in 1977, Code 11 is similar to Code 2 of 5 Matrix and is
primarily used in telecommunications. The symbol can encode any length string
consisting of the digits 0-9 and the dash character (-). One modulo-11 check
digit is calculated.
6.1.2 Code 2 of 5
-----------------
Code 2 of 5 is a family of one-dimensional symbols, 8 of which are supported by
Zint. Note that the names given to these standards alters from one source to
another so you should take care to ensure that you have the right barcode type
before using these standards.
6.1.2.1 Standard Code 2 of 5
----------------------------
Also known as Code 2 of 5 Matrix is a self-checking code used in industrial
applications and photo development. Standard Code 2 of 5 will encode any length
numeric input (digits 0-9).
6.1.2.2 IATA Code 2 of 5
------------------------
Used for baggage handling in the air-transport industry by the International
Air Transport Agency, this self-checking code will encode any length numeric input
(digits 0-9) and does not include a check digit.
6.1.2.3 Industrial Code 2 of 5
------------------------------
Industrial Code 2 of 5 can encode any length numeric input (digits 0-9) and
does not include a check digit.
6.1.2.4 Interleaved Code 2 of 5
-------------------------------
This self-checking symbology encodes pairs of numbers, and so can only encode
an even number of digits (0-9). If an odd number of digits is entered a leading
zero is added by Zint. No check digit is added.
6.1.2.5 Code 2 of 5 Data Logic
------------------------------
Data Logic does not include a check digit and can encode any length numeric
input (digits 0-9).
6.1.2.6 ITF-14
--------------
ITF-14, also known as UPC Shipping Container Symbol or Case Code is based on
Interleaved Code 2 of 5 and requires a 13 digit numeric input (digits 0-9). One
modulo-10 check digit is added by Zint.
6.1.2.7 Deutsche Post Leitcode
------------------------------
Leitcode is based on Interleaved Code 2 of 5 and is used by Deutsche Post for
mailing purposes. Leitcode requires a 13-digit numerical input and includes a
check digit.
6.1.2.8 Deutsche Post Identcode
-------------------------------
Identcode is based on Interleaved Code 2 of 5 and is used by Deutsche Post for
mailing purposes. Identcode requires an 11-digit numerical input and includes a
check digit.
6.1.3 Universal Product Code (EN 797)
-------------------------------------
6.1.3.1 UPC Version A
---------------------
UPC-A is used in the United States for retail applications. The symbol requires
an 11 digit article number. The check digit is calculated by Zint. In addition
EAN-2 and EAN-5 add-on symbols can be added using the + character. For example,
to draw a UPC-A symbol with the data 72527270270 with an EAN-5 add-on showing
the data 12345 use the command:
zint --barcode=34 -d 72527270270+12345
or encode a data string with the + character included:
my_symbol->symbology = BARCODE_UPCA;
error = ZBarcode_Encode_and_Print(my_symbol, "72527270270+12345");
If your input data already includes the check digit symbology 35 can be used
which takes a 12 digit input and validates the check digit before encoding.
6.1.3.2 UPC Version E
---------------------
UPC-E is a zero-compressed version of UPC-A developed for smaller packages. The
code requires a 6 digit article number (digits 0-9). The check digit is
calculated by Zint. EAN-2 and EAN-5 add-on symbols can be added using the +
character as with UPC-A. In addition Zint also supports Number System 1
encoding by entering a 7-digit article number stating with the digit 1. For
example:
zint --barcode=37 -d 1123456
or
my_symbol->symbology = BARCODE_UPCE;
error = ZBarcode_Encode_and_Print(my_symbol, "1123456");
If your input data already includes the check digit symbology 38 can be used
which takes a 7 or 8 digit input and validates the check digit before encoding.
6.1.4 European Article Number (EN 797)
--------------------------------------
6.1.4.1 EAN-2, EAN-5, EAN-8 and EAN-13
--------------------------------------
The EAN system is used in retail across Europe and includes standards for EAN-2
and EAN-5 add-on codes, EAN-8 and EAN-13 which encode 2, 5, 7 or 12 digit
numbers respectively. Zint will decide which symbology to use depending on the
length of the input data. In addition EAN-2 and EAN-5 add-on symbols can be
added using the + symbol as with UPC symbols. For example:
zint --barcode=13 -d 54321
will encode a stand-alone EAN-5, whereas
zint --barcode=13 -d 7432365+54321
will encode an EAN-8 symbol with an EAN-5 add-on. As before these results can
be achieved using the API:
my_symbol->symbology = BARCODE_EANX;
error = ZBarcode_Encode_and_Print(my_symbol, "54321");
error = ZBarcode_Encode_and_Print(my_symbol, "7432365+54321");
All of the EAN symbols include check digits which are added by Zint.
If you are encoding an EAN-8 or EAN-13 symbol and your data already includes
the check digit then you can use symbology 14 which takes an 8 or 13 digit input
and validates the check digit before encoding.
6.1.4.2 SBN, ISBN and ISBN-13
-----------------------------
EAN-13 symbols (also known as Bookland EAN-13) can also be produced from
9-digit SBN, 10-digit ISBN or 13-digit ISBN-13 data. The relevant check digit needs
to be present in the input data and will be verified before the symbol is
generated. In addition EAN-2 and EAN-5 add-on symbols can be added using the +
symbol as with UPC symbols.
6.1.5 Plessey
-------------
Also known as Plessey Code, this symbology was developed by the Plessey Company
Ltd. in the UK. The symbol can encode any length data consisting of digits
(0-9) or letters A-F and includes a CRC check digit.
6.1.6 MSI Plessey
-----------------
Based on Plessey and developed by MSE Data Corporation, MSI Plessey is
available with a range of check digit options available by setting option_2 or
by using the --ver= switch. Any length numeric (digits 0-9) input can be
encoded. The table below shows the options available:
-------------------------------------------
Value of option_2 | Check Digits
-------------------------------------------
0 | None
1 | Modulo-10
2 | Modulo-10 & Modulo-10
3 | Modulo-11
4 | Modulo-11 & Modulo-10
-------------------------------------------
6.1.7 Telepen
-------------
6.1.7.1 Telepen Alpha
---------------------
Telepen Alpha was developed by SB Electronic Systems Limited and can encode any
length of ASCII text input. Telepen includes a modulo-127 check digit.
6.1.7.2 Telepen Numeric
-----------------------
Telepen Numeric allows compression of numeric data into a Telepen symbol. Data
can consist of pairs of numbers or pairs consisting of a numerical digit
followed an X character. For example: 466333 and 466X33 are valid codes whereas
46X333 is not (the digit pair "X3" is not valid). Telepen Numeric includes a
modulo-127 check digit which is added by Zint.
6.1.8 Code 39
-------------
6.1.8.1 Standard Code 39 (ISO 16388)
------------------------------------
Standard Code 39 was developed in 1974 by Intermec. Input data can be of any
length and can include the characters 0-9, A-Z, dash (-), full stop (.), space,
asterisk (*), dollar ($), slash (/), plus (+) and percent (%). The standard
does not require a check digit but a modulo-43 check digit can be added if
required by setting option_2 = 1 or using --ver=1.
6.1.8.2 Extended Code 39
------------------------
Also known as Code 39e and Code39+, this symbology expands on Standard Code 39
to provide support to the full ASCII character set. The standard does not
require a check digit but a modulo-43 check digit can be added if required by
setting option_2 = 1 or using --ver=1.
6.1.8.3 Code 93
---------------
A variation of Extended Code 39, Code 93 also supports full ASCII text. Two
check digits are added by Zint.
6.1.8.4 PZN
-----------
PZN is a Code 39 based symbology used by the pharmaceutical industry in
Germany. PZN encodes a 6 digit number to which Zint will add a modulo-10
check digit.
6.1.8.5 LOGMARS
---------------
LOGMARS (Logistics Applications of Automated Marking and Reading Symbols) is a
variation of the Code 39 symbology used by the US Department of Defence.
LOGMARS encodes the same character set as Standard Code 39 and adds a modulo-43
check digit.
6.1.8.6 Code 32
---------------
A variation of Code 39 used by the Italian Ministry of Health ("Ministero della
Sanità") for encoding identifiers on pharmaceutical products. This symbology
requires a numeric input up to 8 digits in length. A check digit is added by Zint.
6.1.8.7 HIBC Code 39
--------------------
This option adds a leading '+' character and a trailing modulo-49 check digit
to a standard Code 39 symbol as required by the Health Industry Barcode
standards.
6.1.9 Codabar (EN 798)
----------------------
Also known as NW-7, Monarch, ABC Codabar, USD-4, Ames Code and Code 27, this
symbology was developed in 1972 by Monarch Marketing Systems for retail
purposes. The American Blood Commission adopted Codabar in 1977 as the standard
symbology for blood identification. Codabar can encode any length string
starting and ending with the letters A-D and containing between these letters
the numbers 0-9, dash (-), dollar ($), colon (:), slash (/), full stop (.) or
plus (+). No check digit is generated.
6.1.10 Pharmacode
-----------------
Developed by Laetus, Pharmacode is used for the identification of
pharmaceuticals. The symbology is able to encode whole numbers between 3 and
131070.
6.1.11 Code 128
---------------
6.1.11.1 Standard Code 128 (ISO 15417)
--------------------------------------
One of the most ubiquitous one-dimensional barcode symbologies, Code 128 was
developed in 1981 by Computer Identics. This symbology supports full ASCII text
and uses a three-mode system to compress the data into a smaller symbol. Zint
automatically switches between modes and adds a modulo-103 check digit. Code
128 is the default barcode symbology used by Zint. In addition Zint supports
the encoding of Latin-1 (non-English) characters in Code 128 symbols [1]. The
Latin-1 character set is shown in Appendix A.
6.1.11.2 Code 128 Subset B
--------------------------
It is sometimes advantageous to stop Code 128 from using subset mode C which
compresses numerical data. The BARCODE_CODE128B option (symbology 60)
suppresses mode C in favour of mode B.
6.1.11.3 GS1-128
----------------
A variation of Code 128 also known as UCC/EAN-128, this symbology is defined by
the GS1 General Specification. Application Identifiers (AIs) should be entered
using [square bracket] notation. These will be converted to (round brackets)
for the human readable text. This will allow round brackets to be used in the
data strings to be encoded. Fixed length data should be entered at the
appropriate length for correct encoding (see Appendix C). GS1-128 does not
support extended ASCII characters. Check digits for GTIN data (AI 01) are not
generated and need to be included in the input data. The following is an example
of a valid GS1-128 input:
zint --barcode=16 -d "[01]98898765432106[3202]012345[15]991231"
6.1.11.4 EAN-14
---------------
A shorter version of GS1-128 which encodes GTIN data only. A 13 digit number is
required. The GTIN check digit and AI (01) are added by Zint.
6.1.11.5 NVE-18
---------------
A variation of Code 128 the "Nummer der Versandeinheit" standard includes both
modulo-10 and modulo-103 check digits. NVE-18 requires a 17 digit numerical
input and check digits are added by Zint.
6.1.11.6 HIBC Code 128
----------------------
This option adds a leading '+' character and a trailing modulo-49 check digit
to a standard Code 128 symbol as required by the Health Industry Barcode
standards.
6.1.12 GS1 DataBar (ISO 24724)
------------------------------
Also known as RSS (Reduced Spaced Symbology) these symbols are due to replace
GS1-128 symbols in accordance with the GS1 General Specification. If a GS1
DataBar symbol is to be printed with a 2D component as specified in ISO 24723
set option_1 = 2 or use the option --mode=2 at the command prompt. See section
6.3 of this manual to find out how to generate DataBar symbols with 2D components.
6.1.12.1 DataBar-14 and DataBar-14 Truncated
--------------------------------------------
Also known as RSS-14 this standard encodes a 13 digit item code. A check digit
and application identifier of (01) are added by Zint. To produce a truncated
symbol set the symbol height to a value between 32 and 13. Normal DataBar-14
symbols should have a height of 33 or greater.
6.1.12.2 DataBar Limited
------------------------
Also known as RSS Limited this standard encodes a 13 digit item code and can be
used in the same way as DataBar-14 above. DataBar Limited, however, is limited
to data starting with digits 0 and 1 (i.e. numbers in the range 0 to
1999999999999). As with DataBar-14 a check digit and application identifier of
(01) are added by Zint.
6.1.12.3 DataBar Expanded
-------------------------
Also known as RSS Expanded this is a variable length symbology capable of
encoding data from a number of AIs in a single symbol. AIs should be encased in
[square brackets] in the input data. This will be converted to (rounded
brackets) before it is included in the human readable text attached to the
symbol. This method allows the inclusion of rounded brackets in the data to be
encoded. GTIN data (AI 01) should also include the check digit data as this is
not calculated by Zint when this symbology is encoded. Fixed length data should
be entered at the appropriate length for correct encoding (see Appendix C). The
following is an example of a valid DataBar Expanded input:
zint --barcode=31 -d "[01]98898765432106[3202]012345[15]991231"
6.1.13 Korea Post Barcode
-------------------------
The Korean Postal Barcode is used to encode a six-digit number and includes one
check digit.
6.1.14 Channel Code
-------------------
A highly compressed symbol for numeric data. The number of channels in the
symbol can be between 3 and 8 and this can be specified by setting the value of
option_2. It can also be determined by the length of the input data e.g. a
three character input string generates a 4 channel code by default. The maximum
values permitted depend on the number of channels used as shown in the table
below:
--------------------------------------------
Channels | Minimum Value | Maximum Value
--------------------------------------------
3 | 00 | 26
4 | 000 | 292
5 | 0000 | 3493
6 | 00000 | 44072
7 | 000000 | 576688
8 | 0000000 | 7742862
--------------------------------------------
6.2 Stacked Symbologies
-----------------------
6.2.1 Basic Symbol Stacking
---------------------------
An early innovation to get more information into a symbol, used primarily in
the vehicle industry, is to simply stack one-dimensional codes on top of each
other. This can be achieved at the command prompt by giving more than one set
of input data. For example
zint -d 'This' -d 'That'
will draw two Code 128 symbols, one on top of the other. The same result can be
achieved using the API by executing the ZBarcode_Encode() function more than
once on a symbol. For example:
my_symbol->symbology = BARCODE_CODE128;
error = ZBarcode_Encode(my_symbol, "This");
error = ZBarcode_Encode(my_symbol, "That");
error = ZBarcode_Print(my_symbol);
A more sophisticated method is to use some type of line indexing which
indicates to the barcode reader which order the symbols should be read. This is
demonstrated by the symbologies below.
6.2.2 Codablock-F
-----------------
This is a stacked symbology based on Code 128 which can encode ASCII code set
data up to a maximum length of 2725 characters. The width of the Codablock-F
symbol can be set using the --cols= option at the command line or option_2.
Alternatively the height (number of rows) can be set using the --rows= option
at the command line or by setting option_1. Zint does not support encoding of
GS1 data in Codablock-F symbols.
6.2.3 Code 16k (EN 12323)
-------------------------
Code 16k uses a Code 128 based system which can stack up to 16 rows in a block.
This gives a maximum data capacity of 77 characters or 154 numerical digits and
includes two modulo-107 check digits. Code 16k also supports extended ASCII
character encoding in the same manner as Code 128.
6.2.4 PDF417 (ISO 15438)
------------------------
Heavily used in the parcel industry, the PDF417 symbology can encode a vast
amount of data into a small space. Zint supports encoding up to the ISO
standard maximum symbol size of 925 codewords which (at error correction level
0) allows a maximum data size of 1850 text characters, or 2710 digits. The
width of the generated PDF417 symbol can be specified at the command line using
the --cols switch followed by a number between 1 and 30, and the amount of
check digit information can be specified by using the --security switch
followed by a number between 0 and 8 where the number of codewords used for
check information is determined by 2^(value + 1). If using the API these values
are assigned to option_2 and option_1 respectively. The default level of check
information is determined by the amount of data being encoded. This symbology
uses Latin-1 character encoding by default but also supports the ECI encoding
mechanism. A separate symbology ID can be used to encode Health Industry
Barcode (HIBC) data which adds a leading '+' character and a modulo-49 check
digit to the encoded data.
6.2.5 Compact PDF417
--------------------
Also known as truncated PDF417. Options are the same as for PDF417 above.
6.2.6 MicroPDF417 (ISO 24728)
-----------------------------
A variation of the PDF417 standard, MicroPDF417 is intended for applications
where symbol size needs to be kept to a minimum. 34 predefined symbol sizes are
available with 1 - 4 columns and 4 - 44 rows. The maximum size MicroPDF417
symbol can hold 250 alphanumeric characters or 366 digits. The amount of error
correction used is dependent on symbol size. The number of columns used can be
determined using the --cols switch or option_2 as with PDF417. This symbology
uses Latin-1 character encoding by default but also supports the ECI encoding
mechanism. A separate symbology ID can be used to encode Health Industry
Barcode (HIBC) data which adds a leading '+' character and a modulo-49 check
digit to the encoded data.
6.2.7 GS1 DataBar-14 Stacked (ISO 24724)
----------------------------------------
A stacked variation of the GS1 DataBar-14 symbol requiring the same input (see
section 6.1.12.1). The height of this symbol is fixed. The data is encoded in
two rows of bars with a central finder pattern. This symbol can be generated
with a two-dimensional component to make a composite symbol.
6.2.8 GS1 DataBar-14 Stacked Omnidirectional (ISO 24724)
--------------------------------------------------------
Another variation of the GS1 DataBar-14 symbol requiring the same input (see
section 6.1.12.1). The data is encoded in two rows of bars with a central
finder pattern. This symbol can be generated with a two-dimensional component
to make a composite symbol.
6.2.9 GS1 DataBar Expanded Stacked (ISO 24724)
----------------------------------------------
A stacked variation of the GS1 DataBar Expanded symbol for smaller packages.
Input is the same as for GS1 DataBar Expanded (see section 6.1.12.3). In
addition the width of the symbol can be altered using the --cols switch or
option_2. In this case the number of columns relates to the number of character
pairs on each row of the symbol. This symbol can be generated with a two-
dimensional component to make a composite symbol. For symbols with a 2D component
the number of columns must be at least 2.
6.2.10 Code 49
-------------
Developed in 1987 at Intermec, Code 49 is a cross between UPC and Code 39. It
it one of the earliest stacked symbologies and influenced the design of Code
16K a few years later. It supports full 7-bit ASCII input up to a maximum of 49
characters or 81 numeric digits. GS1 data encoding is also supported.
6.3 Composite Symbols (ISO 24723)
---------------------------------
Composite symbols employ a mixture of components to give more comprehensive
information about a product. The permissible contents of a composite symbol is
determined by the terms of the GS1 General Specification. Composite symbols
consist of a linear component which can be an EAN, UPC, GS1-128 or GS1 DataBar
symbol, a 2D component which is based on PDF417 or MicroPDF417, and a separator
pattern. The type of linear component to be used is determined using the -b or
--barcode= switch or by adjusting symbol->symbology as with other encoding
methods. Valid values are shown below.
--------------------------------------------------------------------------------
Numeric | Name | Barcode Name
Value |
--------------------------------------------------------------------------------
130 | BARCODE_EANX_CC | Composite Symbol with EAN linear component
131 | BARCODE_EAN128_CC | Composite Symbol with GS1-128 linear
| | component
132 | BARCODE_RSS14_CC | Composite Symbol with GS1 DataBar-14 linear
| | component
133 | BARCODE_RSS_LTD_CC | Composite Symbol with GS1 DataBar Limited
| | component
134 | BARCODE_RSS_EXP_CC | Composite Symbol with GS1 DataBar Extended
| | component
135 | BARCODE_UPCA_CC | Composite Symbol with UPC A linear component
136 | BARCODE_UPCE_CC | Composite Symbol with UPC E linear component
137 | BARCODE_RSS14STACK_CC | Composite Symbol with GS1 DataBar-14
| | Stacked component
138 | BARCODE_RSS14_OMNI_CC | Composite Symbol with GS1 DataBar-14
| | Stacked Omnidirectional component
139 | BARCODE_RSS_EXPSTACK_CC | Composite Symbol with GS1 DataBar Expanded
| | Stacked component
--------------------------------------------------------------------------------
The data to be encoded in the linear component of a composite symbol should be
entered into a primary string with the data for the 2D component being entered
in the normal way. To do this at the command prompt use the --primary= command.
For example:
zint -b 130 --mode=1 --primary=331234567890 -d "[99]1234-abcd"
This creates an EAN-13 linear component with the data "331234567890" and a 2D
CC-A (see below) component with the data "(99)1234-abcd". The same results can
be achieved using the API as shown below:
my_symbol->symbology = 130;
my_symbol->option_1 = 1;
strcpy(my_symbol->primary, "331234567890");
ZBarcode_Encode_and_Print(my_symbol, "[99]1234-abcd");
EAN-2 and EAN-5 add-on data can be used with EAN and UPC symbols using the +
symbol as described in section 6.1.3 and 5.1.4.
The 2D component of a composite symbol can use one of three systems: CC-A, CC-B
and CC-C as described below. The 2D component type can be selected
automatically by Zint dependant on the length of the input string.
Alternatively the three methods can be accessed using the --mode= prompt
followed by 1, 2 or 3 for CC-A, CC-B or CC-C respectively, or by using the
option_1 variable as shown above.
6.3.1 CC-A
----------
This system uses a variation of MicroPDF417 which optimised to fit into a small
space. The size of the 2D component and the amount of error correction is
determined by the amount of data to be encoded and the type of linear component
which is being used. CC-A can encode up to 56 numeric digits or an alphanumeric
string of shorter length. To select CC-A use --mode=1.
6.3.2 CC-B
----------
This system uses MicroPDF417 to encode the 2D component. The size of the 2D
component and the amount of error correction is determined by the amount of
data to be encoded and the type of linear component which is being used. CC-B
can encode up to 338 numeric digits or an alphanumeric string of shorter
length. To select CC-B use --mode=2.
6.3.3 CC-C
----------
This system uses PDF417 and can only be used in conjunction with a GS1-128
linear component. CC-C can encode up to 2361 numeric digits or an alphanumeric
string of shorter length. To select CC-C use --mode=3.
6.4 Two-Track Symbols
---------------------
6.4.1 Two-Track Pharmacode
--------------------------
Developed by Laetus, Pharmacode Two-Track is an alternative system to
Pharmacode One-Track used for the identification of pharmaceuticals. The
symbology is able to encode whole numbers between 4 and 64570080.
6.4.2 PostNet
-------------
Used by the United States Postal Service until 2009, the PostNet barcode was
used for encoding zip-codes on mail items. PostNet uses numerical input data
and includes a modulo-10 check digit. While Zint will encode PostNet symbols of
any length, standard lengths as used by USPS were PostNet6 (5 digits ZIP
input), PostNet10 (5 digit ZIP + 4 digit user data) and PostNet12 (5 digit ZIP
+ 6 digit user data).
6.4.3 PLANET
------------
Used by the United States Postal Service until 2009, the PLANET (Postal Alpha
Numeric Encoding Technique) barcode was used for encoding routing data on mail
items. Planet uses numerical input data and includes a modulo-10 check digit.
While Zint will encode PLANET symbols of any length, standard lengths used by
USPS were Planet12 (11 digit input) and Planet14 (13 digit input).
6.5 4-State Postal Codes
------------------------
6.5.1 Australia Post 4-State Symbols
------------------------------------
6.5.1.1 Customer Barcodes
-------------------------
Australia Post Standard Customer Barcode, Customer Barcode 2 and Customer
Barcode 3 are 37-bar, 52-bar and 67-bar specifications respectively, developed
by Australia Post for printing Delivery Point ID (DPID) and customer
information on mail items. Valid data characters are 0-9, A-Z, a-z, space and
hash (#). A Format Control Code (FCC) is added by Zint and should not be
included in the input data. Reed-Solomon error correction data is generated by
Zint. Encoding behaviour is determined by the length of the input data
according to the formula shown in the following table:
-----------------------------------------------------------------
Input | Required Input Format | Symbol | FCC | Encoding
Length | | Length | | Table
-----------------------------------------------------------------
8 | 99999999 | 37-bar | 11 | None
13 | 99999999AAAAA | 52-bar | 59 | C
16 | 9999999999999999 | 52-bar | 59 | N
18 | 99999999AAAAAAAAAA | 67-bar | 62 | C
23 | 99999999999999999999999 | 67-bar | 62 | N
-----------------------------------------------------------------
6.5.1.2 Reply Paid Barcode
--------------------------
A Reply Paid version of the Australia Post 4-State Barcode (FCC 45) which
requires an 8-digit DPID input.
6.5.1.3 Routing Barcode
-----------------------
A Routing version of the Australia Post 4-State Barcode (FCC 87) which requires
an 8-digit DPID input.
6.5.1.4 Redirect Barcode
------------------------
A Redirection version of the Australia Post 4-State Barcode (FCC 92) which
requires an 8-digit DPID input.
6.5.2 Dutch Post KIX Code
-------------------------
This Symbology is used by Royal Dutch TPG Post (Netherlands) for Postal code
and automatic mail sorting. Data input can consist of numbers 0-9 and letters
A-Z and needs to be 11 characters in length. No check digit is included.
6.5.3 Royal Mail 4-State Country Code (RM4SCC)
----------------------------------------------
The RM4SCC standard is used by the Royal Mail in the UK to encode postcode and
customer data on mail items. Data input can consist of numbers 0-9 and letters
A-Z and usually includes delivery postcode followed by house number. For
example "W1J0TR01" for 1 Picadilly Circus in London. Check digit data is
generated by Zint.
6.5.4 USPS OneCode
------------------
Also known as the Intelligent Mail Barcode and used in the US by the United
States Postal Service (USPS), the OneCode system replaced the PostNet and
PLANET symbologies in 2009. OneCode is a fixed length (65-bar) symbol which
combines routing and customer information in a single symbol. Input data
consists of a 20 digit tracking code, followed by a dash (-), followed by a
delivery point zip-code which can be 0, 5, 9 or 11 digits in length. For
example all of the following inputs are valid data entries:
"01234567094987654321"
"01234567094987654321-01234"
"01234567094987654321-012345678"
"01234567094987654321-01234567891"
6.5.5 Japanese Postal Code
--------------------------
Used for address data on mail items for Japan Post. Accepted values are 0-9,
A-Z and Dash (-). A modulo 19 check digit is added by Zint.
6.6 Two-Dimensional Matrix Symbols
----------------------------------
6.6.1 Data Matrix ECC200 (ISO 16022)
------------------------------------
Also known as Semacode this symbology was developed in 1989 by Acuity CiMatrix
in partnership with the US DoD and NASA. The symbol can encode a large amount
of data in a small area. Data Matrix ECC200 can encode characters in the
Latin-1 set by default but also supports encoding using other character sets
using the ECI mechanism. It can also encode GS1 data. The size of the
generated symbol can also be adjusted using the --vers= option or by setting
option_2 as shown in the table below. A separate symbology ID can be used to
encode Health Industry Barcode (HIBC) data which adds a leading '+' character
and a modulo-49 check digit to the encoded data. Note that only ECC200 encoding
is supported, the older standards have now been removed from Zint.
---------------------
Input | Symbol Size

28 | 12 x 26
28 | 12 x 36
29 | 16 x 36
30 | 16 x 48
---------------------
To force Zint only to use square symbols (versions 1-24) at the command line
use the option --square and when using the API set the value option_3 =
DM_SQUARE.
Data Matrix Rectangular Extension (DMRE) codes may be generated with the
following values as before:
---------------------
Input | Symbol Size
---------------------
31 | 8 x 48
32 | 8 x 64
33 | 12 x 64
34 | 16 x 64
35 | 24 x 48
36 | 24 x 64
37 | 26 x 48
38 | 26 x 64
---------------------
DMRE symbol sizes may be activated in automatic size mode using the option
--dmre or by the API option_3 = DM_DMRE
6.6.2 QR Code (ISO 18004)
-------------------------
Also known as Quick Response Code this symbology was developed by Denso. Four
levels of error correction are available using the --security= option or by
setting option_1 as shown in the following table.
-------------------------------------------------------------------------
Input | ECC Level | Error Correction Capacity | Recovery Capacity
-------------------------------------------------------------------------
1 | L (default) | Approx 20% of symbol | Approx 7%
2 | M | Approx 37% of symbol | Approx 15%
3 | Q | Approx 55% of symbol | Approx 25%
4 | H | Approx 65% of symbol | Approx 30%
-------------------------------------------------------------------------
The size of the symbol can be set by using the --vers= option or setting
option_2 to the QR Code version required (1-40). The size of symbol generated
is shown in the table below.
---------------------
Input | Symbol Size
---------------------
1 | 21 x 21
2 | 25 x 25

38 | 165 x 165
38 | 169 x 169
39 | 173 x 173
40 | 177 x 177
---------------------
The maximum capacity of a (version 40) QR Code symbol is 7089 numeric digits,
4296 alphanumeric characters or 2953 bytes of data. QR Code symbols can also be
used to encode GS1 data. QR Code symbols can by default encode characters in
the Latin-1 set and Kanji characters which are members of the Shift-JIS
encoding scheme. In addition QR Code supports using other character sets using
the ECI mechanism. Input should usually be entered as Unicode (UTF-8) with
conversion to Shift-JIS being carried out by Zint. A separate symbology ID can
be used to encode Health Industry Barcode (HIBC) data which adds a leading '+'
character and a modulo-49 check digit to the encoded data.
6.6.3 Micro QR Code (ISO 18004)
-------------------------------
A miniature version of the QR Code symbol for short messages. ECC levels can be
selected as for QR Code (above). QR Code symbols can encode characters in the
Latin-1 set and Kanji characters which are members of the Shift-JIS encoding
scheme. Input should be entered as a UTF-8 stream with conversion to Shift-JIS
being carried out automatically by Zint. A preferred symbol size can be
selected by using the --vers= option or by setting option_2 although the actual
version used by Zint may be different if required by the input data. The table
below shows the possible sizes:
---------------------------------
Input | Version | Symbol Size
---------------------------------
1 | M1 | 11 x 11
2 | M2 | 13 x 13
3 | M3 | 15 x 15
4 | M4 | 17 x 17
---------------------------------
6.6.4 Maxicode (ISO 16023)
--------------------------
Developed by UPS the Maxicode symbology employs a grid of hexagons surrounding
a 'bulls-eye' finder pattern. This symbology is designed for the identification
of parcels. Maxicode symbols can be encoded in one of five modes. In modes 2
and 3 Maxicode symbols are composed of two parts named the primary and
secondary messages. The primary message consists of a structured data field
which includes various data about the package being sent and the secondary
message usually consists of address data in a data structure. The format of the
primary message required by Zint is given in the following table:
----------------------------------------------------------------------------
Characters | Meaning
----------------------------------------------------------------------------
1 - 9 | Postcode data which can consist of up to 9 digits (for mode 2)
| or up to 6 alphanumeric characters (for mode 3). Remaining
| unused characters should be filled with the SPACE character
| (ASCII 32).
10 - 12 | Three digit country code according to ISO 3166 (see Appendix B)
13 - 15 | Three digit service code. This depends on your parcel courier.
----------------------------------------------------------------------------
The primary message can be set at the command prompt using the --primary= switch.
The secondary message uses the normal data entry method. For example:
zint -o test.eps -b 57 --primary='999999999840012' -d 'Secondary Message Here'
When using the API the primary message must be placed in the symbol->primary
string. The secondary is entered in the same way as described in section 5.2.
When either of these modes is selected Zint will analyse the primary message
and select either mode 2 or mode 3 as appropriate.
Modes 4 to 6 can be accessed using the --mode= switch or by setting option_1.
Modes 4 to 6 do not require a primary message. For example:
zint -o test.eps -b 57 --mode=4 -d 'A MaxiCode Message in Mode 4'
Mode 6 is reserved for the maintenance of scanner hardware and should not be
used to encode user data.
This symbology uses Latin-1 character encoding by default but also supports the
ECI encoding mechanism. The maximum length of text which can be placed in a
Maxicode symbol depends on the type of characters used in the text.
Example maximum data lengths are given in the table below:
-----------------------------------------------------------------------------
Mode | Maximum Data Lenth | Maximum Data Length | Number of Error
| for Capital Letters | for Numeric Digits | Correction Codewords
-----------------------------------------------------------------------------
2* | 84 | 126 | 50
3* | 84 | 126 | 50
4 | 93 | 135 | 50
5 | 77 | 110 | 66
6 | 93 | 135 | 50
-----------------------------------------------------------------------------
* - secondary only
6.6.5 Aztec Code (ISO 24778)
----------------------------
Invented by Andrew Longacre at Welch Allyn Inc in 1995 the Aztec Code symbol is
a matrix symbol with a distinctive bulls-eye finder pattern. Zint can generate
Compact Aztec Code (sometimes called Small Aztec Code) as well as "full-range"
Aztec Code symbols and by default will automatically select symbol type and
size dependent on the length of the data to be encoded. Error correction
codewords will normally be generated to fill at least 23% of the symbol. Two
options are available to change this behaviour:
The size of the symbol can be specified using the --ver= option or setting
option_2 to a value between 1 and 36 according to the following table. The
symbols marked with an asterisk (*) in the table below are "compact" symbols,
meaning they have a smaller bulls-eye pattern at the centre of the symbol.
---------------------
Input | Symbol Size

---------------------
Note that in symbols which have a specified size the amount of error correction
is dependent on the length of the data input and Zint will allow error
correction capacities as low as 3 codewords.
Alternatively the amount of error correction data can be specified by use of
the --mode= option or by setting option_1 to a value from the following table:
----------------------------------
Mode | Error Correction Capacity
----------------------------------
1 | >10% + 3 codewords
2 | >23% + 3 codewords
3 | >36% + 3 codewords
4 | >50% + 3 codewords
----------------------------------
It is not possible to select both symbol size and error correction capacity for
the same symbol. If both options are selected then the error correction
capacity selection will be ignored.
Aztec Code supports ECI encoding and can encode up to a maximum length of
approximately 3823 numeric or 3067 alphabetic characters or 1914 bytes of data.
A separate symbology ID can be used to encode Health Industry Barcode (HIBC)
data which adds a leading '+' character and a modulo-49 check digit to the
encoded data.
6.6.6 Aztec Runes
-----------------
A truncated version of compact Aztec Code for encoding whole integers between 0
and 255. Includes Reed-Solomon error correction. As defined in ISO/IEC 24778
Annex A.
6.6.7 Code One
--------------
A matrix symbology developed by Ted Williams in 1992 which encodes data in a
way similar to Data Matrix ECC200. Code One is able to encode the Latin-1
character set or GS1 data. There are two types of Code One symbol - variable
height symbols which are roughly square (versions A thought to H) and
fixed-height versions (version S and T). These can be selected by using --vers=
or setting option_2 as shown in the table below:
--------------------------------------------------------------------
Input | Version | Size | Numeric | Alphanumeric
| | | Data Capacity | Data Capacity
--------------------------------------------------------------------
1 | A | 16 x 18 | 22 | 13
2 | B | 22 x 22 | 44 | 27
3 | C | 28 x 28 | 104 | 64
4 | D | 40 x 42 | 217 | 135
5 | E | 52 x 54 | 435 | 271
6 | F | 70 x 76 | 886 | 553
7 | G | 104 x 98 | 1755 | 1096
8 | H | 148 x 134 | 3550 | 2218
9 | S | 8X height | 18 | N/A
10 | T | 16X height | 90 | 55
--------------------------------------------------------------------
Version S symbols can only encode numeric data. The width of version S and
version T symbols is determined by the length of the input data.
6.6.8 Grid Matrix
-----------------
By default Grid Matrix supports encoding in Latin-1 and Chinese characters
within the GB 2312 standard set to be encoded in a checkerboard pattern. Input
should be entered as Unicode (UTF-8) with conversion to GB 2312 being carried
out automatically by Zint. The symbology also supports the ECI mechanism. The
size of the symbol and the error correction capacity can be specified. If you
specify both of these values then Zint will make a 'best-fit' attempt to
satisfy both conditions. The symbol size can be specified using the --ver=
option or by setting option_2, and the error correction capacity can be
specified by using the --security= option or by setting option_1 according to
the following tables:
---------------------
Input | Symbol Size
---------------------
1 | 18 x 18
2 | 30 x 30
3 | 42 x 42
4 | 54 x 54
5 | 66 x 66
6 | 78 x 78
7 | 90 x 90
8 | 102 x 102
9 | 114 x 114
10 | 126 x 126
11 | 138 x 138
12 | 150 x 150
13 | 162 x 162
---------------------
----------------------------------
Mode | Error Correction Capacity
----------------------------------
1 | Approximately 10%
2 | Approximately 20%
3 | Approximately 30%
4 | Approximately 40%
5 | Approximately 50%
----------------------------------
6.6.9 DotCode
-------------
DotCode uses a grid of dots in a rectangular formation to encode characters up
to a maximum of approximately 450 characters (or 900 numeric digits). The
symbology supports ECI encoding and GS-1 data encoding. By default Zint will
produce a symbol which is approximately square, however the width of the symbol
can be adjusted by using the --cols= option or by setting option_2. Outputting
DotCode to raster images (PNG, GIF, BMP, PCX) will require setting the scale of
the image to a larger value than the default (e.g. approx 10) for the dots to
be plotted correctly. Approximately 33% of the resulting symbol is comprised of
error correction codewords.
6.6.10 Han Xin Code
-------------------
Also known as Chinese Sensible Code, Han Xin is a symbology which is still
under
development, so it is recommended it should not yet be used for a production
environment. The symbology is capable of encoding characters in the GB18030
character set (up to 4-byte characters) and is also able to support the ECI
mechanism. Han Xin does not support the encoding of GS-1 data.
The size of the symbol can be specified using the --ver= option or setting
option_2 to a value between 1 and 84 according to the following table.
---------------------
Input | Symbol Size
---------------------
1 | 23 x 23
2 | 25 x 25
3 | 27 x 27
4 | 29 x 29

82 | 185 x 185
83 | 187 x 187
84 | 189 x 189
---------------------
There are four levels of error correction capacity available for Han Xin Code
which can be set by using the --mode= option or by setting option_1 to a value
from the following table:
--------------------------
Mode | Recovery Capacity
--------------------------
1 | Approx 8%
2 | Approx 15%
3 | Approx 23%
4 | Approx 30%
--------------------------
It is not possible to select both symbol size and error correction capacity for
the same symbol. If both options are selected then the error correction
capacity selection will be ignored.
6.7 Other Barcode-Like Markings
-------------------------------
6.7.1. Facing Identification Mark (FIM)
---------------------------------------
Used by the United States Postal Service (USPS), the FIM symbology is used to
assist automated mail processing. There are only 4 valid symbols which can be
generated using the characters A-D as shown in the table below.
----------------------------------------------------------------------------
Code Letter | Usage
----------------------------------------------------------------------------
A | Used for courtesy reply mail and metered reply mail with a
| pre-printed PostNet symbol.
B | Used for business reply mail without a pre-printed zip code.
C | Used for business reply mail with a pre-printed zip code.
D | Used for Information Based Indicia (IBI) postage.
----------------------------------------------------------------------------
6.7.2 Flattermarken
-------------------
Used for the recognition of page sequences in print-shops, the Flattermarken is
not a true barcode symbol and requires precise knowledge of the position of the
mark on the page. The Flattermarken system can encode any length numeric data
and does not include a check digit.
6.7.3 DAFT Code
---------------
This is a method for creating 4-state codes where the data encoding is provided
by an external program. Input data should consist of the letters 'D', 'A', 'F'
and 'T' where these refer to descender, ascender, full (ascender and descender)
and tracker (neither ascender nor descender) respectively. All other characters
are ignored.

A. Character Encoding
=====================
This section is intended as a quick reference to the character sets used by
Zint. All symbologies use standard ASCII input as shown in section A.1, but
some support extended character support as shown in the subsequent section.
A.1 ASCII Standard
------------------
The ubiquitous ASCII standard is well known to most computer users. It's
reproduced here for reference.
-------------------------------------------------------------
Hex | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7
-------------------------------------------------------------
0 | NULL | DLE | SPACE | 0 | @ | P | ` | p
1 | SOH | DC1 | ! | 1 | A | Q | a | q

4 | EOT | DC4 | $ | 4 | D | T | d | t
5 | ENQ | NAK | % | 5 | E | U | e | u
6 | ACK | SYN | & | 6 | F | V | f | v
7 | BEL | ETB | ' | 7 | G | W | g | w
8 | BS | CAN | ( | 8 | H | X | h | x
9 | TAB | EM | ) | 9 | I | Y | i | y
A | LF | SUB | * | : | J | Z | j | z
B | VT | ESC | + | ; | K | [ | k | {
C | FF | FS | , | < | L | \ | l | |
D | CR | GS | - | = | M | ] | m | }
E | SO | RS | . | > | N | ^ | n | ~
F | SI | US | / | ? | O | _ | o | DEL
-------------------------------------------------------------
A.2 Latin Alphabet No 1 (ISO 8859-1)
------------------------------------
A common extension to the ASCII standard, Latin-1 is used to expand the range
of Code 128, PDF417 and other symbols. Input strings should be in Unicode
format
------------------------------------------------------
Hex | 8 | 9 | A | B | C | D | E | F

C. GS1 General Specification
----------------------------
The GS1 General Specification defines a global standard for encoding data about
products. Data is encoded as a series of number pairs where the first number,
usually shown in (brackets) is an application identifier (AI), and the second
is a formatted representation of the data. For example (21)6773 can be read as
"Serial Number 6773" where the AI (21) signifies that the data is a serial
number. Note that when using Zint AI data is entered using [square] brackets.
This allows rounded brackets to be included in the data which is allowed by the
specification. When the barcode symbol is generated these square brackets are
replaced by rounded brackets in any text displayed. A list of valid AI numbers
is given below.

standard length field. Zint will generate an error if the correct data lengths
are not entered. The following table details which AIs have fixed length data
fields and how long the data should be for each:
