v0.3.2

Stirling Office Convert 0.3.2

PDF to Office

• MathJax and KaTeX formulas (Obsidian, browser exports) are rebuilt from their layout: real sub- and superscripts in XLSX, ODS, ODT, HTML, Markdown and PPTX, and native Word equations in DOCX with fractions, roots, limits, nested scripts and cases
• Formula tables keep overbars, hats and tildes on their letters (x̄, π̂, x̃), radicals read as √, and a repeated table header is not glued into the previous page's last row
• Content in hidden layers is left out; damaged PDFs open in every feature; garbled pages no longer show junk text
• Fonts drawn smaller than their own cap height are sized by what is drawn; .notdef codes and placeholder spaces no longer show as stray characters or hide word gaps
• Highlights shade the words under them, barcodes keep their modules, CalRGB and clamped colours match viewers, small pages keep their size, column breaks land in the right column
• One failed paint no longer drops the rest of a page
• Output is deterministic: the same input gives byte-identical files

PDF/A

• Passes the remaining veraPDF rules on almost all of the pdf.js corpus at every level, and all of pdfium's tests
• u and a levels keep text as extractable as b
• Unembedded CJK and CID fonts get stand-ins that cover their text, so pages no longer render blank
• Transfer functions, soft masks, JPEG 2000 colour and CalGray are rendered correctly when flattening

Line art

• As fast as 0.3.1 with identical output, and light yellow and orange fills stay solid

App

• Every CLI output format is available in the web app, with the same option parsing, plus a sheet mode for XLSX and ODS
• The app's page script loads again (it stopped on a syntax error, leaving the format picker empty)

Speed and safety

• Script detection, glyph lookup, Arabic font matching, sheet lookups and PDF/A token counting are faster (HTML/EPUB to PDF about 15% less CPU, PDF to DOCX about 8%)
• Formula, overline and radical work is capped for hostile input, and equation text drops characters that are not valid XML

API

• Removed undocumented public members that nothing used: PdfTableExtractor, Units.* except emu(), ExtractedTable.toGrid, ExtractedCell.isMerged, CellStyle.withAlignment, PdfOutput.hasDestination, HtmlDocument.targetBookmark
