Welcome to version 0.1.11. The changes in this version have mainly focused on stability. There is a breaking API change.

We have also started to run tests against a larger corpus of documents from Common Crawl allowing us to find bugs and malformed files proactively. This release is screened against 6000 additional files.

  • Improvements to content and font parsing detected by fuzzing inputs.
  • Improvements and resiliency for finding the startxref location when parsing a file..
  • Adds build and tests for Mac OS as well as retrieving system fonts on iPad (Mac Catalyst).
  • Support clipping when rendering XObjects.
  • Prevent malformed files leading to an out-of-memory when decompressing streams.
  • Make IGraphicsStateOperationFactory and ReflectionGraphicsStateOperationFactory public.
  • Softmask support for images.
  • Performance improvements using Span and ReadOnlyMemory where available.
  • Handle corrupt files where the stream contains comment tokens.
  • Improvements to copying from existing files when using PdfDocumentBuilder, fixes some bugs with copying fonts and dictionary tokens referenced indirectly.
  • Handle corrupt files with double endstream definitions.
  • More tolerant parsing for a number of invalid PDFs, including invalid USC2 input, CMAP formats, CFF fonts, missing font subtypes, invalid xref table positions, missing /FirstChar entry for font dictionaries and corrupt ASCII 85 encoded data.
  • Fix an issue where adding content to an existing PDF using PdfDocumentBuilder could result in upside-down or wrongly positioned text due to global transforms in the source PDF.
  • New option to completely skip annotations when building a document.
  • Prevent infinite loops in certain documents [#1096].
  • Improved performance when tokenizing numbers, this should provide a minor speed improvement.
  • When adding a page from an existing PDF to a PdfDocumentBuilder any external link annotations should be preserved.

Breaking changes

The method on PdfDocumentBuilder:

public PdfPageBuilder AddPage(PdfDocument document, int pageNumber, Func<PdfAction, PdfAction?>? copyLink)

Has been changed to wrap the copyLink parameter in an options object to support the KeepAnnotations option:

public PdfPageBuilder AddPage(PdfDocument document, int pageNumber, AddPageOptions options)

You can just set the CopyLinkFunc property in the options object if you need to access this functionality.
