The 2022 Volume 3 release comes with digital signatures and programmatic support to add or remove annotations in the PDF Viewer, as well as headers for Diagram container objects.
This feature allows users to add a header block to the container objects.
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 .NET 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.
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.
This feature renders digital signatures in the PDF Viewer control, but the user cannot interact with them.
This feature allows users to focus on and navigate form fields in PDF documents with a tab order index. This helps them edit the form fields in the PDF effortlessly.
This feature allows users to add, remove, or modify the annotations programmatically using the existing PdfLoadedDocument’s API.
Preserve structure tags in converted PDF documents for accessibility (PDF/UA or 508 compliance) support.
Wavy, wavy heavy, wavy double, and double underline styles render as they are in the input Word document.
