• Now identifies unsupported signature algorithms when profiling, even if you can't verify signatures that use them.
• Improved recovery of truncated files that make use of compressed XRef streams.
• Ensured dates extracted from XMP as...

Updates in v2.29.2

Features

• Added support for OpenType variable fonts - see the OpenType.Axes class.
• For customers that were relying on the pre-2.29 XMP validation model, added the OutputProfiler.setUseLegacyXMPModel() method.

Fixes

Updates in v2.29.1

Features

• PDF Association declarations now only refer to WCAG 2.2, so the OutputProfile feature has been updated to match this.
• Viewer: Added the ability to set minimum length for search term in SearchField.

Fixes

• Fixed minor issues to ensure the PDF API runs correctly under Java 24.
• Fixed XMP issues relating to typed values and qualifiers, added JSON-LD serialization.
• Locally buffer content being hashed for signature creation, to fix disastrous performance for Amazon CloudHSM v5 signatures...

Updates in v2.29

Features

• XMP extension types are now scoped to their schema, so XMP.getType() method returns only global types. Added a new XMP.Schema.getType() method.
• Added support for EA-PDF 1.0 specification to XMP.
• Added support for creating a PDFImage from 16-bit TIFF images.
• Added the Measurement class, for real-world dimensions on images and pages, and support creation of Geospatial PDF from GeoTIFF images (requires GeoTools).
• Added PDFStyle.superscriptClone(size, position) to force a particular size...

Updates in v2.28.8

Fixes

• Fixed ICC profiles that have no perceptual space (fall back to relative).
• Fixed edge-case when resampling imagemasks to match images.
• Fixed a couple of very obscure issues from the PDF Association "pdf-differences" collection, designed to test rendering fidelity.
• Fixed SignatureProvider.SignatureState bug in the Viewer, introduced in previous release.

Released: Nov 14, 2024

Updates in v2.28.7

Features

• Made a minor adjustment to PKCS7SignatureHandler.SigningEngine.getTimeStampResp interface, to make it easier to implement a custom SigningEngine.
• The legacy "Border" attribute on annotations is now supported.
• Improved the Font Substitution algorithm, used when rasterizing a PDF with unembedded fonts.
• Various changes have been made to make merging of tagged documents (such as PDF/UA documents created by BFO Publisher and Report Generator) easier.
• Viewer: Made adjustments to allow a...

Released: Aug 22, 2024

Updates in v2.28.6

Fixes

• Fixed rendering of bitmap images with more than 2^31 samples, and of very large JPX images that are downsampled before cropping.
• Fixed rendering of files containing unclosed paths before other operations.
• Previous release built Graal support classes with Java 11, which would break classloaders that foolishly verify classes themselves rather then letting the application test them in a try/catch (Websphere, specifically). Rebuilt with Java 8.
• Concatenating PDFs that made use of bfo:sort and...

Released: Jun 14, 2024

Updates in v2.28.5

Features

• The process for repairing errors in the Structure Tree hierarchy has been improved to the point where almost any hierarchy can be made technically, if not semantically, valid.

• Improved to HtmlDerivation algorithm.
• Added a new WidgetAnnotation...
