other than for digits (worse for TEX 7-11 embedded in extended) and for
returning X12/EDI at EOD - will cause changes in encodation;
allow for GS1 GS in B256 (should never happen);
some re-jigging of dm200encode and fiddling with dm_isXXX;
remove some DM_DEBUG from dm_placementbit
The `__has_feature` macro is a clang extension that works like a macro. If
zint is being compiled using a compiler other then clang, `__has_feature`
is not defined. As it is not defined, it cannot be used as a function call
expression. Any environment that doesn't have `__has_feature` should prevent
the preprocessor from "seeing" the invokation of the macro, as invoking
undefined macros is not supported by the C language.
The usual procedure to assure this would be a construction like
\#if defined(__has_feature)
\# if __has_feature(...)
\# endif
\#endif
which, combined with the GCC check we have here, would result in a
3 level nesting of if and elseif expressions .. and that's without
covering microsoft's compiler.
For this purpose, Qt >= 5.13 has been defining the `__has_feature`
macro on non-clang environments, while defining all (clang) features
to not be available. This allows to write feature checks with "less"
nesting, as we have here.
Mimic Qt-5.13's behavior and provide the `__has_feature` macro if
it's not provided otherwise (either by clang or by Qt), allowing the
function-call-like expression to be parsed on those systems.
PDF417 & CODABLOCKF due to height/scale rounding by changing
out_large_bar_height() to return scaled int values for raster,
props codemonkey82 (#204)
raster/vector.c: const some vars
vector.c: rect_count, last_start_row UPC/EAN only
library.c: check for stacking symbols >= 200
add specify rows option (option_3) (#204);
warn if cols increased from specified (back-incompatible);
move table definitions from "pdf417.h" to new "pdf417_tabs.h" and
make INTERNAL_DATA and share with composite.c (saves ~10K);
prefix routines and tables with "pdf_";
some small performance improvements through if/elses, pdf_textprocess()
& pdf_numbprocess() loop simplifications
MICROQR: fix debug access crash on printing non-NUL-terminating binary
DATAMATRIX: fix missing ++ from "[tp]" at C40/TEXT EOD processing of GS1
(though probably never reached); use "[tp++]" throughout
Add const to static tables missing it and also to some variables
Change "debug" -> "debug_print" throughout
- 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
Rename barcode funcs to same as BARCODE_XXX name
library: barcode funcs array for dispatch, used for ZBarcode_ValidID() also
general: change is_sane() comparison to nonzero from ZINT_ERROR_INVALID_OPTION
MAILMARK: fuller error messages
CODABAR: add option to show check character in HRT
zint.h: use 0xNNNN for OR-able defines
GUI: add guard descent height reset button, add Zint version to window title,
static get_zint_version() method, use QStringLiteral (QSL shorthand),
use SIGNAL(toggled()), add errtxt "popup" and status bar, add icons,
add saveAs shortcut, add main menu, context menus and actions, add help,
reset_view() -> reset_colours(), add copy to clipboard as EMF/GIF/PNG/TIF,
lessen triggering of update_preview(), shorten names of getters/setters,
simplify/shorten some update_preview() logic in switch,
CODEONE disable structapp for Version S
qzint.cpp: add on_errored signal, add missing getters, add test
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
also avoid distributive multiplication with floats to lessen chances of
platform variation (#204 ARM-Cortex crash)
- raster.c: Don't allow for text if scale < 1.0
- raster.c: Cast some indexes to (size_t) to allow for large scale
- vector.c: Check malloc()s and return ZINT_ERROR_MEMORY on fail
- raster/vector.c: various var name changes & other code fiddling
- library.c: Check that scale/height/whitespace/border are reasonable values:
scale (0.01-100), height (0-500), whitespace_width/height (0-100),
border_width (0-100)
- CLI: allow both e.g. '-height' and '--height' (getopt_long_only())
- gif.c: fix GIF_ZLW_PAGE_SIZE -> GIF_LZW_PAGE_SIZE
- GUI: allow whitespace/scale to 100
