Focus of this Release: Text Field Precision with the "Comb Flag"

We have significantly upgraded FormVu's ability to accurately reproduce the appearance of forms that rely on the comb flag property in PDF text fields. This feature is critical for forms where characters must be visually spaced out and aligned within individual, equally sized boxes.

Latest Refinements:

We continue to refine FormVu's core engine to deliver uncompromising quality and reliability.

  • Better Handling of Ultra-Thin Graphics: We have improved the handling of 1-pixel-sized images or lines that are subject to scaling. Previously, if these elements were scaled below 1-pixel, they might not have been rendered in the output. They are now correctly output, preserving all minor graphical details of the original document.
  • Adjusted Form Element Attributes: Output for form element attributes has been adjusted for improved consistency.

Critical Fixes for Reliable Conversions

This release includes important fixes to eliminate conversion errors and improve overall stability, particularly in handling complex PDF structure and recursion.

  • Fixed Recursive Action Loop: Resolved a StackOverflowError caused by a recursive loop in an Action's /Next key, which previously halted the file conversion process.
  • Corrected File Attachment Decoding: Fixed a bug where the /P value in a FileAttachment annotation would decode incorrectly.
  • Prevented NullPointerExceptions: Fixed an issue where a null /Dest value would cause a NullPointerException, ensuring the conversion successfully finishes.

With these updates, FormVu reinforces its position as the reliable solution for migrating complex forms, delivering high-fidelity conversions with enhanced precision. Explore the full release notes and updated documentation for more details.
