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
vertical whitespace, as they're decorative rather than functional (#247)
Allow for dot overspill in height of vertical box sides (dotty mode)
Move is_dotty(), is_fixed_ratio() from library.c to common.c
and restrict sequence to max 10,000, add button icons;
make Export dialog sizable and show every 100 results, add button icon;
fix saving CHANNEL option, fix Export painting main window (Windows), fix
guard descent not-resetting
qzint: add getAsCLI(), warnLevel(), extra isStackable()/isComposite() etc
Add ZBarcode_BarcodeName()
manual: doc above, some fixes, tweaks
- 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
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
PLESSEY: add options NCR weighted mod-10, hide check digit(s) in HRT
test suite: now runnable under MSVC 2019, 2017, 2015, MinGW/MSYS
win32/README: update with MSVC 2019 and CMake instructions
The testcommon library, which is outside of this link unit, is
referencing the INTERNAL functions, so despite the name they
need to be exported. The export code is copy&pasted from the
ZINT_EXTERN definition which can't be reused over preprocessor
limitations.
We might just use ZINT_EXTERN instead though
Patch from Michael <virtual_worlds@gmx.de>
Full text: As usual I have modified only minor things to remove warnigs when compiled as C++ code, have added some const-specifiers where possible to help the compiler create more efficient code and added some static-specifiers to make functions invisible to other modules.
Original email reads...
It does not contain any fundamental changes or new functions but a lot of improvements which I have done over time (added several const/static specifiers, replaced repeated if-conditions by if-else, removed some warnings).
