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$" in prep for l10n (maybe);
`is_sane/is_sane_lookup()` -> `not_sane/not_sane_lookup()`,
returning 1-based position (zero on failure) instead of bool;
`long` ints -> plain `int` (except those dealing with `ftell()`,
`fread()` etc) as depend on int being 32-bits already
GUI: in "grpDATF.ui" use "PlainText" rather than "RichText" for
tracker ratio examples as height of text messing up sometimes
manual: clarify Codablock-F length maximum & add examples
docs: README: pandoc 3.5, Ubuntu 24.04
CMake: use "-Wpedantic" for Clang only as GNU complains about
`errtxtf()` positional args "%n$"
outputting to in-memory buffer `symbol->memfile` instead of to
file `symbol->outfile`, ticket #301
Add "README.clang-tidy" and ".clang-tidy" options file
Suppress some warnings
`gs1_verify()` by checking length before `to_int()`, ticket
#300 (#11), props Andre Maute
CODEONE: fix out-of-bounds crash for Version T by upping buffer
size to same as for A to H, ticket #300 (#12), props Andre Maute
GS1_128_CC: fix divide-by-zero crash in `calc_padding_ccc()` by
allowing for min linear width 68 in `cc_width` calc, ticket #300
(#13), props Andre Maute
BWIPP: update `bwipp_dump.ps` to latest version, update
`gen_gs1_lint.php` to accommodate `req` "+"
PDF417: change `liste[]` int -> short to lessen stack usage
Some variable name and code fiddlings
in `cc_binary_string()`, ticket #300 (#5 & #6), props Andre Maute;
add other checks for length on processing encoding mode
PDF417: fix out-of-bounds crash on overrunning string and codeword
buffers by tripling size (convert to `short` instead of `int` to
guard against too much stack), ticket #300 (#7 & #10), props Andre
Maute; (TODO: add some checks instead to bail out earlier?)
CODEONE: fix looping on latch crash in `c1_encode()`, ticket #300 (#8),
props Andre Maute
CODABLOCKF: fix crash on negative overflow of `columns` (`option_2`),
ticket #300 (#9), props Andre Maute
library: add `debug_print_escape()` helper for ZINT_DEBUG_PRINT
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)
`pdf_num_stay()` to not call it if previous/next block is BYT;
also extend `pdf_asciix[]` to full 256 byte range (defensive & also can
use directly rather than checking range, ticket #300, props Andre Maute
`EANUPC_GUARD_WHITESPACE`, CLI `--guardwhitespace`) (ticket #287)
EAN-2/EAN-5: HRT now at top instead of at bottom for standalones,
following BWIPP
CLI: batch mode: don't close input if stdin
EAN/UPC: fix excess 1X to right of add-ons
Composites: fix excess whitespace; fix quiet zone calcs to allow
for linear shifting
CLI: use own (Wine) version of `CommandLineToArgvW()` to avoid
loading "shell32.dll"
Move "font.h" -> "raster_font.h"
EPS/SVG: use new `out_putsf()` func to output floats, avoiding
trailing zeroes & locale dependency
EPS: simplify "TR" formula
SVG: change font from "Helvetica, sans serif" to "OCR-B, monospace";
use single "<path>" instead of multiple "<rect>"s to draw boxes
(reduces file size)
Add `EMBED_VECTOR_FONT` to `output_options` (CLI `--embedfont`) to
enable embedding of font in vector output - currently only for
SVG output of EAN/UPC
GUI: use "OCR-B" font for EAN/UPC and "Arimo" for all others (was
"Helvetica" for both); paint background of screen preview light
grey so as contrasts with whitespace and quiet zones
EMF: prefix funcs with `emf_`; simplify string `halign` handling
large: rename `large_int` -> `large_uint`
CODE128/common: move `c128_hrt_cpy_iso8859_1()` to
`hrt_cpy_iso8859_1()` and add `ZINT_WARN_HRT_TRUNCATED` warning
(for future use)
Various symbologies: replace `printf()` with `fputs()`
(symbol->debug)
QRCODE: better assert(), removing a NOLINT (2 left)
CLI: add some more barcode synonyms for DBAR
common: various fiddlings
CMake: don't include png.c unless ZINT_USE_PNG (avoids clang
warning)
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
spanning Text segments to avoid affecting 1st char of 2nd segment
- PDF417/MICROPDF417: add optimized encoding, FAST_MODE for
previous scheme; formatting changes
- common.c/h: add `cnt_digits()`, comments in include and make more
consistent, minor code fiddling
- DOTCODE: replace `dc_n_digits()` with new `cnt_digits()`
- test_qr: fix `test_qr_perf()`
- composite: minor code fiddling
- library: debug dump HIBC-processed input
- BWIPP: update to latest

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
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

GRIDMATRIX, MAXICODE, MICROPDF417, PDF417, QRCODE, ULTRA
DOTCODE: use pre-calculated generator poly coeffs in Reed-Solomon for
performance improvement
