encodation in certain cases (and no pessimizations found so far),
props lyngklip (BWIPP);
fix extended char latching when exactly 3 extended chars at end;
count code set C (not digits) in loop deciding when to
shift/latch to extended for better estimate
AZTEC: return warning if ECC < 5% (due to bit-stuffing when version
given); return error if > 22 layers (Zint 26) for Reader
Initialisation symbol requested for better error message
AZTEC/HANXIN/QRCODE: consolidate different ECC data size tables
into one indexed by ECC
DBAR_EXP: check for reduced length <= 77 up front for better error
message
HANXIN: use `malloc()` rather than `z_alloca()` for large binary
array
QRCODE: `ecc_level` now 0-based (not 1-based)
MICROQR: consolidate different version end routines into one
`microqr_end()` and use new `microqr_data` table to simplify code
MICROPDF417: use table for max codewords per column
library: centralize all error messages using new `errtxt()`,
`errtxtf()`, `errtxt_adj()` funcs that protect `symbol->errtxt`
from overflow, & try to make error messages more consistent
thru-out, adding more feedback info to many, & use positional
args "%n$" in prep for l10n (maybe);
`is_sane/is_sane_lookup()` -> `not_sane/not_sane_lookup()`,
returning 1-based position (zero on failure) instead of bool;
`long` ints -> plain `int` (except those dealing with `ftell()`,
`fread()` etc) as depend on int being 32-bits already
GUI: in "grpDATF.ui" use "PlainText" rather than "RichText" for
tracker ratio examples as height of text messing up sometimes
manual: clarify Codablock-F length maximum & add examples
docs: README: pandoc 3.5, Ubuntu 24.04
CMake: use "-Wpedantic" for Clang only as GNU complains about
`errtxtf()` positional args "%n$"
`iso3166list` linter and adjusting all others to allow for
multiple optional linters (by checking `data_len` vs `offset`)
library: change invalid `input_mode` reset to return warning;
split func table into 2 - func declarations without prototype
will be error in C23;
make invalid symbology check a separate function using a table
and call near beginning of `ZBarcode_Encode_Segs()`;
in `ZBarcode_BarcodeName()` save some bytes by simplifying
name table and removing "BARCODE_" prefix from entries
output: fix pack logic to use pragma by default (actually more
portable than `__attribute__`)
common.h: remove C99 detection which was artifice of specifying
"-std=", and rejig layout to be more logical
BWIPP: update to latest version
general: change `ZINT_VERSION_BUILD` tests to `#if`s
general: further fiddling with some tables to save a few bytes
CLI: change function arg `optarg` -> `arg` so doesn't shadow
global
general: library now compilable with Comp Cert C (though as it
doesn't support `alloca()` will have multiple memory leaks)
test `ferror()` also in `fm_err()` if `err` zero and file
NetBSD: add instructions and some workarounds (`getopt_long_only()`
in particular)
qzint: check `__GNUC__` version for "-Wstringop-truncation"
suppression
ticket #300, props Andre Maute;
fix 4-layer compact block max (76 -> 64);
fix encoding of byte-blocks > 11-bit limit
library: fix 21-bit Unicode conversion in `escape_char_process()`;
fix restricting escaped data length by using de-escaped length to
check (`escape_char_process()` adapted to do length only calc
also)
rename `ZINT_CAP_EXTENDABLE` -> `ZINT_CAP_EANUPC`
(`ZINT_CAP_EXTENDABLE` marked as legacy)
CODE128: increase no. symbol chars max 60 -> 99
EAN-2/EAN-5: fix `BARCODE_BIND_TOP/BIND/BOX` output
GS1_128: warn if data > 48 (GS1 General Specifications max)
common: `is_extendable()` -> `is_ucpean()`
raster: add `ZFONT_HALIGN_CENTRE/LEFT/RIGHT` flags and process
in `draw_string()` (for drawing EAN/UPC outside digits), and
for `ZFONT_HALIGN_CENTRE` round when calculating centre
(shifts some texts 1 pixel left)
raster/vector: use offsets into `symbol->text` for EAN/UPC
instead of `out_upcean_split_text()` (removed)
BMP/EMF/GIF/PCX/PNG/PS/SVG/TIF: use new `out_colour_get_rgb()`
routine (replaces `colour_to_XXX()`)
general: simplify/fix some `error_number` handling/returning
frontend: truncate overlong `--primary` instead of ignoring;
negative floating pt option (for `--textgap`)
man page: list size detail for matrix symbols (`--vers`)
manual: further fiddling with scaling text; some typos
(was only set on BMP output to length of BMP pixel array)
EXCODE39: change to display check digit in HRT by default
CODE39/EXCODE39/LOGMARS: new hidden check digit option
(`option_2 = 2`)
qr.c: suppress bogus gcc-13 warning (only appears on optimize)
GUI: move some symbology-specific options into Data Tab so
separate tab unnecessary (those with few options and no
Composite/ECI), namely: all C25XXX, CODE39/EXCODE39/LOGMARS,
MSI_PLESSEY, CODABAR, DAFT, DPD, MAILMARK_2D, ITF-14, PZN,
UPNQR, CHANNEL, CODE93 and VIN, adjusting grp uis.
change Data dialog button (ellipsis) QToolButton -> QPushButton
& vice versa zap/clear/eye/swap/scale buttons QPushButton ->
QToolButton for better mac compat (also makes sense);
remove some mac hacks that no longer seem necessary;
use folder icon for Export dialog directory button
manual: document new Symbology-specific groupbox & CODE39/etc
hidden check digit option; add annexes on Qt and Tcl backends;
narrow some tables for better txt output;
remove echoed image tags in txt (pandoc 3.1.5 regression?);
add one-page HTML output to Makefile; also tex output (debug);
add class attributes to images to aid HTML styling;
various other fiddlings
Allow `--embedfont` for non-EAN/UPC SVG also (& update GUI)
SVG: add "fonts/normal_woff2.h"; use array syntax for it &
"fonts/upcean_woff2.h" to avoid large strings
GUI: embed Arimo (via "fonts/normal_ttf.h"), same as OCRB
Change textgap max 5X -> 10X

improvements
EMF/PCX/PNG/TIF only, i.e. excluding EPS, GIF & SVG)

various default buttons; use new `takesGS1AIData()` to

Add FAST_MODE input_mode flag and --fast CLI/Tcl option that selects older
faster ISO algorithm (may be used by other symbologies in the future)
and "Fast Encoding" checkbox to Data Matrix GUI
GUI: adds Zint version numbers to DATAMATRIX sizes.
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
add specify rows option (option_3) (#204);
warn if cols increased from specified (back-incompatible);

(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)

- 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_";
