The DLLs-only package of Aspose.PDF for .NET 24.6 enables creating and manipulating PDF documents for .NET developers with an enhanced set of features.

Key Highlights

New Features:

• Inject alternative text for image stamps to enhance accessibility with this C# API version.
• Generate accessible PDFs with low-level functions for better control.
• Digitally sign PDF documents using X509Certificate2 in base64 format for increased security using the latest .NET PDF API release.

Enhancements:

• Relaxed evaluation mode restrictions for a simplified developer experience.
• The paragraph replacement functionality within existing PDFs has been improved for easier editing.
• We have introduced the ability to define areas where text retrieval should be prevented in Aspose.PDF for .NET 24.6.

Bug Fixes:

Several issues related to HTML to PDF conversion, text extraction, PDF/A conversion, and more have been fixed in this release.
