Word Library

Word-to-PDF conversion enhancements

Wavy, wavy heavy, wavy double, and double underline styles render as they are in the input Word document.

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.

Now, the Syncfusion WinUI PDF Library 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

  • Provided support to get OCSP and CRL details from existing digitally signed PDF documents to verify the LTV.
  • Provided an API to choose between OCSP and CRL to validate the LTV in a PDF document.

PDF Redaction

Redaction is the process of permanently removing sensitive or confidential data from a PDF document. Now, the Syncfusion WinUI PDF Library supports true PDF redaction. It can redact text, annotations, and form fields from a PDF document.

Redact PDF

External OCR engine

The Syncfusion OCR processor library uses the Tesseract OCR engine by default to extract text from scanned PDFs and images.

Now users can 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.
