New Improvements in Forms Flattener 4.2 Release

Datalogics has announced the release of Forms Flattener 4.2, introducing significant improvements to its PDF forms processing capabilities.

Key benefits of PDF Forms Flattener for developers

  • Enhanced Compatibility: Flattened PDFs are universally viewable, eliminating issues with unsupported form features on different platforms.
  • Improved Security: By embedding form data directly into the document, the tool prevents unauthorized alterations and safeguards sensitive information.
  • Optimized Performance: Removing interactive elements reduces file complexity, leading to faster load times and more efficient processing.

Bug Fixes and Stability Improvements in Forms Flattener 4.2

  • Corrected an issue where flattening some XFA documents caused errors when a TextEdit field was shared across multiple pages.
  • Resolved an erroneous error that could occur when exporting form data from an AcroForms document in specific cases.
  • Fixed a rare crash caused by corrupted memory when flattening an XFA document.
  • Introduced support for flattening AcroForms as if printed, ensuring a more accurate representation of forms in their final state.

Additional Enhancements Made to Adobe PDF Library

Datalogics has also released a new version of our PDF SDK, Adobe PDF Library. The newest version is APDFL v18.0.5PlusP1g.

Key highlights of APDFL v18.0.5PlusP1g release include:

  • Advanced Form Flattening in C++/C: A new method, PDDocFlattenAcroFormFieldsAsIfPrinted(), has been added to the C++/C interface for FormsExtension, allowing developers to flatten AcroForm fields as they would appear when printed.
  • Improved Page Content Recognition: The .NET and Java interfaces now include the RecognizePageContents() method in the Page class, enabling more efficient extraction and identification of page elements.

Enhanced OCR Capabilities: The OCR engine has been upgraded with new overloads of the PlaceTextUnder() method:

  • A resolution parameter has been introduced, providing greater control over OCR output in .NET and Java.
  • A MissingFontStrategy parameter has been added, offering better handling of missing fonts during text placement.

Additionally, this release updates the package versions across key platforms:

  • NuGet package version has been increased to 18.45.0.
  • Maven package version has been increased to 18.45.0.

With these enhancements, Adobe PDF Library continues to empower developers with robust tools for optimizing PDF workflows, improving form handling, and ensuring precise OCR text placement. Visit the Adobe PDF Library product page to download a free trial of the latest version.
