gitlost	6f7cdd660c	- Add special symbology-specific escape sequences (Code 128 only) ... for manual Code Set switching via `input_mode` flag `EXTRA_ESCAPE_MODE` (CLI `--extraesc`) (ticket #204) - GUI: disable "Reset" colour if default; add "Unset" to Printing Scale dialog (allows unsetting of X-dim/resolution settings without having to zap) - library: guard against out-of-bounds rows (negative) - test suite: fix some clang-tidy warnings; slight coverage improvements	2023-01-15 00:22:43 +00:00
gitlost	e1522e0808	backend: non-functional code-fiddling: format codablock.c (clang-format ... + manual); add SPDX to all files; prefix include guards with Z_; move vim comment to bottom; remove some trailing spaces	2022-09-13 21:16:31 +01:00
gitlost	fab7435fac	Performance improvements for linear encoding and raster output ... - use fixed-length string tables (mostly) instead of (char *) pointer ones (saves ~40K) - re-use C128Table for CODABLOCKF and CODE16K (required removal of Stop character and extra CODE16K-only entry) - use pointer to destination and copy (memcpy/strcpy(), bin_append_posn()) instead of concatenating (strcat()) (mostly) - replace last remaining bin_append()s with bin_append_posn(); bin_append() removed - add length arg to toupper() and expand() (avoids strlen()) - change is_sane() to use table-based flags (avoids an iteration) - rename lookup() to is_sane_lookup() and change to check and return posns and use in pointer to destination loops (avoids strcat()s) - remove special case PHARMA in expand() (dealt with in pharma()) - make #define SILVER/CALCIUM/TECHNETIUM/KRSET etc static strings - replace strchr() -> posn() - CODE128: populate destination once in checksum loop; re-use and export some more routines (c128_set_a/b/c(), c128_put_in_set()) for sharing; prefix defines (SHIFTA -> C128_SHIFTA etc) and existing exported routines - use factor XOR toggle trick in checksum calcs (avoids branch) - raster.c: fill out single 1-pixel row and copy using new draw_bar_line(), copy_bar_line() routines; similarly in buffer_plot compare previous line & copy if same (same technique as used to improve non-half-integer scaling, significant performance increase, (c) codemonkey82); also done for PNG (BMP/GIF/PCX/TIFF not done) - raster/vector/output.c: shorten "output_" prefix -> "out_"; sync vector to other raster changes to try to keep source files similar - 2of5.c: prefix "c25_" JAPANPOST: return error if input data truncated (backward incompatible) DAFT: max chars 50 -> 100 common.c: istwodigit() -> is_twodigit() common.c/emf.c/output.c: use some further stripf()s (MSVC6 float variations) library.c: new check_output_args() helper zint.h: add BARCODE_LAST marker and use in library.c QRCODE: remove a NOLINT (requires clang-tidy-13), one remaining CMake: separate no-optimize from ZINT_DEBUG into new ZINT_NOOPT option	2021-10-20 23:05:30 +01:00
gitlost	eb6e5daa2d	raster.c: need ceilf(large_bar_height * si) to avoid zero height rows; ... also improve non-half-int interpolation performance raster/vector.c: use new stripf() func in "common.c" to workaround gcc 32-bit float calculation variations gs1.c: allow dummy AI "[]" if GS1NOCHECK_MODE and has data (#204); also add note re TPX AI 235 and terminating FNC1 Remove trailing whitespace in various files	2021-09-26 23:55:16 +01:00
