- API: add new zint_symbol dpmm field for output resolution (BMP/
EMF/PCX/PNG/TIF only, i.e. excluding EPS, GIF & SVG) - Add support for specifying scale by X-dimension and resolution with new option `--scalexdimdp` for CLI/Tcl & new API function `ZBarcode_Scale_From_XdimDp()` (+ `ZBarcode_XdimDp_From_Scale()` & `ZBarcode_Default_Xdim()`) and new GUI popup; manual: document - BMP/EMF/PCX/PNG/TIF: use new `dpmm` resolution field (for EMF following Inkscape) - backend_qt: add `dpmm()`, `vectorWidth()`, `vectorHeight()`, `noPng()`, `getVersion()`, `takesGS1AIData()`, & `XdimDp` stuff incl. new `QZintXdimDp` struct for passing around scale vars & use in `getAsCLI()`; add comments - Raise `scale` limit to 200 (from 100) to allow for large dpmm - output: create directories & subdirectories as necessary for output path using new function `out_fopen()` and use in BMP/EMF/ EPS/GIF/PCX/PNG/SVG/TIF - DPLEIT/DPIDENT: format HRT according to (incomplete) documentation, and set default height to 72X (from 50X) - CODE128B renamed to CODE128AB as can use subsets A and/or B - CODABAR: fix minimum height calc - EMF: fix indexing of handles (zero-based not 1-based) - GUI: fix symbology zap (previous technique of clearing and re-loading settings without doing a sync no longer works); fix UPCEAN guard descent enable - MAILMARK: better error message if input < 14 characters - GUI: add "Default" button for DAFT tracker ratio & enable/disable various default buttons; use new `takesGS1AIData()` to enable/disable GS1-specific checkboxes - CLI: use new `validate_float()` to parse float options (7 significant digits allowed only, no scientific notation) - DATAMATRIX/GRIDMATRIX/PDF417/QR/ULTRA: micro-optimize structapp ID parse - library/CLI: fiddle with static asserts (make CHAR_BIT sensitive, supposedly) - win32/README: update building libpng (assembly removed) - README.linux: document incompatibility of Qt6 >= 6.3 - manual: expand Barcode Studio waffle - test suite: change range separator to hyphen and allow multiple excludes
