Previously in the WinUI AutoComplete control, the matched text appeared with its selected text. In addition to this, now it supports auto-appending the matched text with a slightly faded-out color. This is inspired by the Windows 11 app search UI in the OS.

Refer to the following image.

Word Library

Word-to-PDF conversion enhancements

The WinUI Word Library now supports rendering wavy, wavy heavy, wavy double and double underline styles as they appear in the input Word document.

PDF Library

The new updates in the WinUI PDF Library are as follows.

Create PDF digital signatures with LTV using a time-stamp URL

Long-term validation (LTV) means that all the information that needs to be verified in the digital signature will be embedded within the PDF file.

Now, the Syncfusion WinUI PDF Library digitally signs a PDF document with LTV using just a time-stamp URL. We can download all the necessary details, such as certificate chain, OCSP (Online Certificate Protocol), and CRL (Certificate Revocation List) from the given URL and embed them into the PDF document.

PDF digital signature enhancements

  • Get OCSP and CRL details from existing, digitally signed PDF documents to verify the LTV.
  • Use 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.

Refer to the following image.

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 enhancements

  • 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 package.

WPF

The new updates for the Syncfusion WPF platform are as follows.

Diagram

Container enhancement

The WPF Diagram control now allows you to add a dedicated header block to the container. Though it was previously possible at the app level, it resulted in the overlapping of the elements in certain cases. With this new support, this issue will not occur since the container smartly resizes itself considering the header block.

Render digital signatures

Render digital signatures in the PDF Viewer, even though the user cannot interact with them.
