/* large.h - Handles binary manipulation of large numbers */
/*
libzint - the open source barcode library
Add multiple segments support for AZTEC, CODEONE, DATAMATRIX, DOTCODE,
GRIDMATRIX, HANXIN, MAXICODE, MICROPDF417, PDF417, QRCODE, RMQR, ULTRA
RMQR: fix ECI encoding (wrong bit length for indicator)
MICROQR: check versions M1 and M2 for allowed characters so as to give
better error messages
DOTCODE: some small optimizations
common.c: add is_chr(), segs_length(), segs_cpy()
CODEONE/CODE128/DOTCODE/GRIDMATRIX/HANXIN/MAXICODE/QRCODE/ULTRA: add
namespace prefixes to static funcs/data
includes: use Z_ prefix, unuse double underscore prefixes (guard defines)
manual.txt: compress some tables using double/treble column sets

RMQR: update to ISO/IEC 23941:2022 - R13x77 numeric cclens change 8 -> 7
QRCODE: use stricter interpretation of ZINT_FULL_MULTIBYTE, excluding
certain trailing bytes
libzint: fix some confusing error messages introduced by segment stuff
general: new escape chars \U, \d and \o
backend_qt: fudge rendering of border rectangles due to scaling/translation
rounding errors TODO: better fudge
GUI: foreground/background colours -> text boxes and icon buttons, add swap
button, independently movable picker (NULL parent), preview colour changes,
preview Data Window changes, add clear data (del) buttons, add zap button
and Factory Reset menu option, various other fixes
libzint: remove STATIC_UNLESS_ZINT_TEST, use wrappers
CMake: add find package QtSvg, remove QtXml
manual: split symbology and general specs and sort, move DAFT to 4-state,
UPC/EAN -> EAN/UPC, DataBar -> GS1 DataBar always, expand MAILMARK info,
various other fiddlings
man page: options or -> |, expand MSI Plessey check digit options
README.linux: add packages info
