Datalogics Releases Adobe PDF Library 18 Updates

Datalogics Inc., the premier source for Adobe PDF and enterprise document management technologies, releases a minor update to its flagship PDF SDK, the Adobe PDF Library (APDFL).

In addition to this release, Datalogics also released a new tutorial video for using APDFL on NuGet, along with several other new APDFL-related videos on their YouTube channel.

New Features

• Adds support for ignoring an Object Label exception when processing a problematic document if the RelaxedSyntax flag is set.
• Adds support for rendering a Page with a problematic Inline Image when the RelaxedSyntax flag is enabled.
• With this release, the Java and .NET Interfaces version has been increased to 18.0.4.15.
• With this release, the NuGet package version has been increased to 18.15.0.

Bug fixes

• Improves the output size for TrueType font programs when possible for Re-subsetting using the PDFOptimizer.
• Corrects an issue in which an erroneous exception could be raised attempting to Optimize a document.
• Corrects an issue in which rendering a Page with an Invalid Dash Phase specified could hang.
• Corrects an issue in which memory corruption could occur when Color Converting an Image with a Separation colorspace.
• Corrects an issue in which saving a document using the RemoveASCIIFilters flag resulted in a corrupted image.
• Corrects an issue in the C++ Print common code in which the Flattener Transparency Quality was not being properly set.

NOTE: The TransQuality member of the PDFLPrintUserParamsRec struct is now available on Non-Windows platforms.

• Corrects an issue in which PDF/X-4 conversions could result in very large increases in image size; Corrects an issue in which PDF/X-4 conversions could misplace an Image relative to its SMask image.
• Corrects an issue which could occur when optimizing an Image with a Soft Mask containing a /Matte entry.
• Corrects an issue in which rotated images were erroneously downsampled during optimization.
• Corrects an issue in which an error could occur while calling dlpdftextadvance() when using the in-memory filesystem.
• Corrects an issue in which color could be rendered incorrectly when specifying a RenderIntent of AbsoluteColorimetric while rendering a document.
• Corrects an issue in which rendering a portion of a Rotated Page could sometimes result in truncated content when using the .NET or Java interfaces.
• Corrects an intermittent crash that could occur while flattening a page with an atypical JPG compressed image.
• Corrects an issue in which a Linearized Save would hang when processing a Document that has Circular References.

NOTE: This changes APDFL's Save with Linearized behavior when processing documents that suffer from Circular Recursion, now an explicit error is raised indicating the problem. This can be caught and handled, if the user still wishes to save they can re-attempt to do so without the Linearized flag.

• Corrects an issue in which rendering a document with very large values could result in some content not being drawn.
• Correct an issue in which an Image with a SMask could be downsampled incorrectly.
