Aspose.PDF FOSS for .NET v26.7.0

A large update, with major gains across text extraction and replacement, HTML to PDF, rendering and imaging, fonts, forms/XFA, signatures, PDF/A, plus several new subsystems.

New subsystems and formats

  • PDF <-> SVG: a real conversion engine (replaces the previous stub).
  • Markdown: Document.Save(SaveFormat.Markdown) and Markdown to PDF import.
  • PDF Comparison (Aspose.Pdf.Comparison): document diff model and optimizers.
  • PDF 3D annotations: read /Subtype /3D artwork, views, and cross-sections.
  • Dynamic XFA flatten renderer: paints XFA forms onto real pages (engine, script runtime, pagination and master pages), producing findable flat AcroForm fields.

Text extraction and replacement

  • CR/LF line structure and blank/trailing-line fidelity in TextFragmentAbsorber.Text.
  • RTL/bidi (Arabic, Hebrew) logical-order reordering and shaped-form logicalization.
  • CJK / Type0-CID extraction with per-page font dedup; ligature (fi/fl/ffi) handling.
  • Post-replace reflow with font-fit, cross-operator replace, subset-missing-glyph fallback, rotated-text model, Pure-mode character grid, hOCR reconstruction.

Rendering, raster and images

  • Image alt-text get/set; inline-image (BI/ID/EI) enumeration in ImagePlacementAbsorber.
  • 1-bpc /Decode [1 0] inversion fix; TIFF Brightness for 1bpp/CCITT; JPEG encoder (4:2:0 and optimized Huffman, SOF1); .ttc per-subfamily font resolution; Page.AddImage page-rotation compensation; XImage.Save emits a DPI-preserving JPEG; PdfConverter TIFF page range.

Fonts

Embedding and subsetting semantics, real-family FindFont, CJK fallback, RemoveUnusedFonts GC, vertical writing mode (DW2/W2).

Forms, AcroForm and XFA

Extensive AcroForm appearance and flatten fixes, checkbox/radio/comb layouts, XFA/AcroForm two-way sync, FDF/XFDF/XML export and import, multiline auto-size.

Signatures

SHA-1, DSA and ECDSA signing, multi-revision, LTV /DSS, DocMDP certify, encrypted-input sign and verify.

Annotations

FreeText appearance and alignment, redaction, line-flatten arrows, stamps (facade and page stamps), XFDF stamp imagedata.

PDF/A, PDF/UA and Tagged

Conversion gating, font-subset optimize, auto-tagging (figures and tables), logical-structure tag trees.

Save and optimize

Linearization on save, incremental-save stamp persistence, lossless palette re-encode, orphan pruning.
