Release Highlights

Aspose.PDF for C++ 25.2 on Windows introduces support for PDF/X-4, an advanced low-level dictionary API for PDF structure manipulation, and enhanced font handling during HTML export. This version enhances stamping, signing, and memory-safe PDF rendering on Windows.

New Feature

• CosPdfDictionary API: Read, modify, and iterate over PDF dictionaries with CosPdfDictionary and its key/value primitives.
• New PDF Conformance: Added support for PdfFormat::PDF_X_4.
• Signature Metadata:
  • Introduced SignatureName for accessing name/identity of a signature.
  • SignatureLengthMismatchException added for signature size validation.
• Stamps & Form Fields:
  • Access X/Y indent of ImageStamp.
  • New constructor for TextBoxField with rectangle array.
• HTML Font Handling: HtmlSaveOptions::SaveFullFont updated with new getter/setter methods for cleaner property control.

Enhancement

• Property simplifications: Rectangle::Empty now accessed via get_Empty() static method.
• Refined control of font saving behavior for full font or subset.

Fix

• No API removals in this version. All updates are additive and backward-compatible.
