UTF-16LE, GBK, separate GB18030, UTF-32BE, UTF-32LE
add examples to tests for DATAMATRIX, HANXIN, QRCODE
HANXIN: Remove alternating filler in function information;
GB 18030 now ECI 32 (previously used ECI 29);
fix gate-posts on codeword limits
use new ZXing-C++ HanXin detector (diagnostics2 branch) for tests
check against ISO/IEC 20830:2021 (no substantive changes)
backend_tcl: update ECIs; NOTE: changed names "unicode" -> "utf-16be",
"euc-cn" -> "gb2312"
GRIDMATRIX/HANXIN/QRCODE/RMQR: warn if auto-conversion (i.e. no ECI given)
occurs to resp. specialized char sets (GB 2312/GB 18030/Shift JIS)
DMATAMATRIX: fix look ahead BASE256 use of dm_text_sp_cnt() on switching;
simplify dm_add_tail()
GUI: check suffixes on save so don't go into error state;
use native path for Save As clipboard message
CODE128: use gs1_check_digit() for NVE18 and EAN14
- 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
GRIDMATRIX, MAXICODE, MICROPDF417, PDF417, QRCODE, ULTRA
DOTCODE: use pre-calculated generator poly coeffs in Reed-Solomon for
performance improvement
PDF417/MICROPDF417: use common routine pdf417_initial()
GUI: code lines <= 118, shorthand widget_obj(),
shorten calling upcean_addon_gap(), upcean_guard_descent()
various backend: var name debug -> debug_print
bmp/emf/ps.c: allow for foreground colour in ULTRA
bmp/gif/pcx.c: allow for BARCODE_STDOUT (fflush/fclose)
emf.c: hexagon rotation field not used; dont't use float index in font loop; Windows stdout binary mode
png.c: remove unused 8-bit; simplify libpng error handling and fclose outfile on error
ps.c: fix buffer overflow on colour_to_pscolor() CMYK
tif.c: fix BLACKISZERO indexes
CODE39: simplify check digit setting
reedsol.c: rs_uint_init_gf() log/alog tables must be zeroed
ZBarcode_Encode: debug: fix access out-of-bounds on non-NUL-terminated source if length < 10
manual.txt/zint.h: document NUL-terminated strings
tests: cover further cases for output (bmp/emf/etc), eci/gb18030/gb2312/sjis, reedsol, AZTEC, CODE39
