Zint Barcode Studio Changelog

What's new in Zint Barcode Studio 2.13.0

Dec 19, 2023
  • Buffer lengths of members `fgcolour` and `bgcolour` in `zint_symbol` extended 10 -> 16 to allow for "C,M,Y,K" comma-separated decimal percentage strings
  • CMYK values for EPS (slightly) and TIF (significantly) have changed - now use the same RGB -> CMYK formula
  • Text (HRT) placement for vector (EMF/EPS/SVG) output changed - for EAN/UPC slightly further away from barcode, for all others slightly nearer. Some horizontal alignments of EAN/UPC vector text also tweaked
  • Text (HRT) for standalone EAN-2 and EAN-5 now at top of symbol (was at bottom)
  • Text height (font size) for SMALL_TEXT vector output reduced
  • For Windows, filenames are now assumed to be UTF-8 encoded. Affects `outfile` in `zint_symbol` and all API filename arguments
  • Never-used `fontsize` member removed from `zint_symbol`
  • Buffer length of member `text` (HRT) in `zint_symbol` extended 128 -> 200 (client buffers may need checking/extending)
  • Font of text of SVG vector output now "OCRB, monospace" (EAN/UPC) or "Arimo, Arial, sans-serif" (all others) (was "Helvetica, sans-serif" for both)
  • Unintended excess horizontal whitespace of Composite symbols removed, and quiet zone settings respected exactly, and centring of HRT (if any) now relative to linear part of symbol only rather than whole symbol
  • Unlikely-to-be-used `bitmap_byte_length` member removed from `zint_symbol` (was only set on BMP output to length of BMP pixel array)
  • EXCODE39 now defaults to displaying check digit in Human Readable Text (HRT)
  • GS1_128 now warns if data > 48 (GS1 General Specifications max)
