Updates in 2022 Volume 3

Funktionen

• PDF Library
  • Create PDF digital signatures with LTV using a time-stamp URL - Long-term validation, or LTV, means that all the information needed to verify the digital signature is embedded within the PDF file. The Syncfusion .NET PDF Library now digitally signs a PDF document with LTV using a time-stamp URL only. All the necessary details such as certificate chain, OCSP, and CRL can be downloaded from the given URL and embedded into the PDF document.
  • PDF digital signature enhancements:
    • Added support for getting OCSP and CRL details from existing digitally signed PDF documents to verify the LTV.
    • Added an API to choose between OCSP and CRL to validate the LTV in a PDF document.
  • External OCR engine - The Syncfusion OCR processor library uses the Tesseract OCR engine by default to extract text from scanned PDFs and images. Users can now change the default OCR engine to external OCR services from Microsoft Azure, AWS, Google, and more.
  • HTML-to-PDF conversion enhancement:
    • The Syncfusion HTML-to-PDF converter now uses the Chromium Blink rendering engine by default to convert HTML pages to PDF documents. The Blink rendering engine supports all the modern features supported by Google’s Chrome browser.
    • You no longer need to set the path for Blink binaries. By default, it is copied to the bin folder while installing the HTML-to-PDF converter NuGet packages.
• Microsoft PowerPoint Library
  • PowerPoint-to-PDF conversion enhancements - Added the ability to preserve structure tags in converted PDF documents for accessibility (PDF/UA or 508 compliance) support.
• Microsoft Word Library
  • Word-to-PDF conversion enhancements - Wavy, wavy heavy, wavy double, and double underline styles now render as they are in the input Word document.
