Introduce new section properties which are responsible for defining columns in the section.

PdfStreamWriter stream-copy page splitting performance is much slower than expected in some cases. When working with larger PDF files, the processing time can increase a lot and cause noticeable delays.

Incorrect Chinese characters due to font data loss during import-export.

NullReferenceException is thrown then exporting a document with a Type 3 font with missing/invalid Unicode mapping.

When a style doesn't have explicitly defined font, the font from the default character properties (\defchp) is used when present. Instead, the font used for the style should be the default font for the document, defined with \deffN tag.
The same issue occur when the doesn't contain \defchp at all. In this case, the font for the style is not imported, but instead the defined with  \deffN tag should be used.

The construction is not common, and MS Word for example doesn't produce such documents.

Introduce calculation chain functionality. This will provide a better mechanism for handling dependent expressions.

When the document contains hidden PDF layers they are imported as visible which leads to additional content in the exported document.

NetStandard: Missing content due to empty glyph outlines in embedded TrueType font subsets.

Workaround 1

Fully embed the fonts in the result PDF document:

Workaround 2

Switch to a .NET Framework project environment and use the .NET Framework PdfProcessing packages.

Respect thread culture when formatting dates with the "\@" switch during mail merge.

This is the stack trace: 

When inserting a specific Jpeg image with an ICC profile there is a problem when opening the file in Adobe: 



On the other hand, the PDF is successfully opened by browsers and most PDF viewers.

Provide a way to export filters.

Currently, the export of lists to text is not supported.

When importing HTML content to a RadFlowDocument and exporting it to PDF format, the following error message occurs:

Duplicated page content due to an incorrect caching mechanism.

When a document containing a SignatureField is exported with the IsEncrypted property set to true, a not set UserPassword is required to open it, which makes it impossible to be opened. An InvalidOperationException is thrown with the message "Password is not correct." when importing with PdfProcessing; Adobe Acrobat also doesn't recognize the password.

Workaround: Exporting with AES256 encryption does not have this problem:

 

NullReferenceException is thrown when exporting pages containing images with missing optional ColorSpace.

XMP metadata is unescaped during import/export.

When signing more than one signature field, the previous signatures are invalidated.

Images don't move with cells when a row/column is inserted.
