What's New in v0.34.0

Highlights

  • PPTX to PDF conversion -- added a full PPTX conversion path with slide shape, image, table, SmartArt fallback, SVG blip, crop, and text rendering support.
  • Improved PowerPoint fidelity -- fixed theme color luminosity transforms with HSL luminance handling, improving Office-compatible color output.
  • Inherited placeholder text layout -- preserves layout/master placeholder alignment, spacing, line spacing, empty paragraphs, and hanging bullet indentation.
  • PPTX benchmark coverage -- added Asian Pacific PPTX issue files, reference PDFs, rendered comparison images, benchmark scripts, and conversion automation.
  • CLI, GUI, and web polish -- updated converter entry points, README content, localized docs, API/Web behavior, and GUI flow around the expanded conversion support.

Validation

  • Focused PPTX tests: dotnet test tests/MiniPdf.Tests --filter "PptxToPdfConverterTests" --no-restore -- 18/18 passed.
  • Full test suite: dotnet test tests/MiniPdf.Tests --no-restore -- 134/134 passed.
  • Library build: dotnet build src/MiniPdf/MiniPdf.csproj --no-restore -- 0 errors.
  • Asian Pacific PPTX benchmark: overall 0.9226, visual average 0.8567, text similarity 0.9499.
