    • Waterfall.
    • Treemap.
    • Box and Whisker.
    • Sunburst.
    • Pie of Pie.
  • Enhanced Fallback Font Support - This feature now includes 38 additional scripts, covering complex scripts, Latin scripts, and symbols. It ensures accurate rendering of characters and symbols during DOCX-to-PDF and image conversions when the specified font does not contain the required glyphs.
• .NET PowerPoint Library
  • Advanced Chart Preservation - PPTX-to-PDF and image conversions now support additional advanced chart types, ensuring precise formatting and visual fidelity to the original Word document. Newly supported chart types include:
    • Waterfall.
    • Treemap.
    • Box and Whisker.
    • Sunburst.
    • Pie of Pie.
  • Enhanced Fallback Font Support - This feature now includes 38 additional scripts, covering complex scripts, Latin scripts, and symbols. It ensures accurate rendering of characters and symbols during PPTX-to-PDF and image conversions when the specified font does not contain the required glyphs.
• .NET PDF Library
  • PDF/X-1a:2001-compliant document creation - Support for creating PDF/X-1a:2001-compliant documents has been added for cross-platform applications. This enhancement ensures reliable output for print workflows and meets industry-standard publishing requirements for high-quality, consistent results.
  • OCR enhancements - The following enhancements have been added to the OCR engine to improve the accuracy and performance of text recognition.
    • Upgrade to Tesseract 5 - The OCR processor supports the latest Tesseract 5 engine, offering superior recognition accuracy and faster processing. This upgrade ensures improved handling of complex layouts, multilingual content, and documents with challenging text structures.
    • Integrated image preprocessing - An advanced image preprocessor is built into the OCR workflow to prepare images for optimal recognition. This reduces errors and improves clarity before text extraction. The preprocessor includes:
      • Grayscale conversion: Removes color data to simplify text detection.
      • Deskew: Corrects tilted or rotated text for proper alignment.
      • Denoise: Eliminates speckles and artifacts that interfere with recognition.
      • Contrast adjustment: Enhances text visibility against backgrounds.
      • Binarization: Converts images to sharp black-and-white using advanced thresholding for clearer text edges.
• Java Word Library
  • Enhanced Word comparison accuracy - Document comparison accuracy has now been improved by integrating the Longest Common Subsequence (LCS) algorithm. This enhancement aligns comparison results more closely with those of Microsoft Word, delivering a more accurate and reliable document diffing experience.
• Visual Studio Extension
  • Syncfusion Document SDK Extension - Syncfusion has introduced the Document SDK Extension, enabling developers to build Blazor applications using powerful document processing components for PDF, Excel, Word, and PowerPoint without relying on Microsoft Office or Adobe tools.
