New In This Release

Version 10.10 is primarily a bugfix release.

New Options

  • Added an option to underline DGN text data fields when converting CAD to PDF. (CADConvertOptions.SetUnderlineTextDataFields())
  • Added an option to set a preferred OCR engine for PDF to HTML conversion in e_reflow_full mode.(HTMLOutputOptions.SetPreferredOCREngine())
  • Added an option to embed a timestamp token into a digital signature. (CMSSignatureOptions.AddTimestampToken())
  • Added an option to allow all tables on each page to be on its own single sheet when converting from PDF to Excel using the StructuredOutput Module. (ExcelOutputOptions.SetPageSingleSheet())


  • [pdf] Added support for converting .log files to pdf in Convert.ToPdf(), Convert.StreamingPDFConversion() and Convert.UniversalConversion().
  • [pdf] Annots.FreeText.GetLineColor() now returns the standard border color when the non-standard entry does not exist. Previously only the non-standard entry would be used.
  • [pdf] Improved the logic for recovering corrupted object streams during PDF parsing.
  • [pdf] Added support for repairing corrupt PDF files that include bad content in between otherwise valid PDF objects. Previously loading these files could throw a "doc root not found" exception.
  • [java] Updated Iterator classes and Annot.BorderStyle to implement Autocloseable, allowing them to be used in try-with-resources blocks.
  • [xfdf] Added font subsetting for inline annotation appearances when exported to XFDF. This improvement minimizes the output file size.
  • [pdf] Fixed occasional unwanted line breaks introduced by subscript or superscript content during text extraction.
  • [pdfa] Adjusted conversion to PDF/A-1 to utilize flattening to avoid cases where image soft mask conversion would produce notable visual artifacts.
  • [cad] Added support for using embedded DWF fonts on Windows.
  • [cad] Now allow CAD to PDF font substitution to optionally draw from a provided RSC file. (refer to for details on how fonts are substituted).
  • [node.js] Added support for Node 22.
  • [node.js] Added support for electron versions 27-30.
  • [python] Added CAD module as a package to pip.


  • [image] Suppressed some error messages related to TIFF tags which were previously written to standard output.
  • [xfdf] Fixed an issue in XFDF/FDF import using PDFDoc.FDFUpdate() or PDFDoc.MergeXFDF(), occuring when the ink list sizes of an annotation were different from the original in the PDF. Previously this could cause an "Index out of range" exception or a failure to update the Ink annotation.
  • [.net] Fixed an unhandled exception crash that would occur in PDFViewWPF when the Open URL Dialog was used or PDFViewWPF.OpenURLAsync() was called.
  • [pdf] Fixed an issue with SDFDoc.GetObj() on corrupt documents where the XRef table did not specify all objects. Previously using digital signature verification or calling methods like Obj.GetOffset() could result in a "can't be invoked on Obj of this type." exception.
  • [pdf] Added missing Objective-C APIs to support custom signing with the RSASSA-PSS algorithm.
  • [pdf] Fixed an undesirable vertical shift of text that could sometimes occur in FreeText annotation appearances on macOS ARM64. (Apple M1, M2, M3 CPUs)
  • [pdfa] When converting to PDF/A, now use the alternate color space if the icc color profile of an image is invalid or not supported. Previously the profile could trigger a "Not a valid ICC color profile" validation error for the output file.
  • [image] Fixed a potential crash due to stack overflow when attempting to convert a corrupt or improperly named image to PDF using Convert.StreamingPDFConversion() or Convert.UniversalConversion() with Filter input.
  • [image] Fixed an issue with TIFF to PDF conversion that could occur when the TIFF resolution units were not specified. Previously this could lead to huge PDF page dimensions that would be rejected by some PDF consumers.
  • [pdf] Fixed round artifacts that could occur in PDF rendering when the thin line scaling option was set to 6.0 or higher.
  • [pdf] Fixed an issue where inserting pages from one document to another could fail due to exceptions from processing corrupt logical structure.
  • [pdf] Fixed a rare issue with pdf processing where references to non-existent Type3 font characters and naming collisions could lead to a incorrect resources being used.
  • [pdf] Fixed an issue with FreeText appearance generation where an empty rich-text style attribute "fontfamily" would cause the generated appearance to be blank.
  • [pdf] Fixed PDF rendering issues in overprint mode caused by incorrect handling of some blend modes when painting on top of spot color ink.
  • [pdf] Fixed a small memory leak when using AlgorithmIdentifier in the C++, Python, Ruby, PHP, Go and Objective-C versions of the SDK.
  • [pdf] Fixed text rendering in PDFDraw in very rare cases where there is an embedded OpenType/CFF font that is incorrectly missing a cmap table.
  • [pdf] Fixed the handling of Unicode characters in the headers of the comment summary for Print.StartPrintJob(). Previously non-ascii characters would be escaped using the hexadecimal Unicode value.
  • [cad] Fixed an issue with incorrect text justification when converting certain DXF files to PDF.
