Corrupted character spacing when exporting PDF/A compliance document with embedded subset fonts.

Glyphs Overlap Due to Incorrect Casting of Glyph Widths from Double to Int.

InvalidOperationException is thrown when exporting a PDF document with a set compliance that processes Type3 font glyphs.

Workaround: Before export, set compliance to None.

 

Update the "fx:Version" metadata mapping for the XRechnung conformance level.

MethodAccessException is thrown when exporting documents using .NET Standard references in a .NET Framework environment.

PdfProcessing: Signature validation reports file as "modified" while Adobe Acrobat reports "not modified".

NullReferenceException is thrown when importing a document with missing Owner (O) in tagged structure attributes.

The stack shows 1070 repeated frames of:

• StructElementObject.ProcessChildPrimitive(...)
• StructElementObject.CopyPropertiesTo(...)

The StructureTree import is traversing a cyclic StructElement graph (or equivalent re-entrant child chain) without a recursion guard.

During this recursion, indirect object resolution repeatedly re-enters the same compressed object:

• reference.ObjectNumber = 554
• context.CurrentIndirectReference.ObjectNumber = 554
• TryGetIndirectObject(554, ...) == false at re-entry

PdfStreamWriter: Duplicated pages when merging documents with identical page content streams but different per-page Resources.

Workaround: Use the RadFixedDocument.Merge() method instead of the PdfStreamWriter.

Error 141 TYPECHECK on Lexmark printer when printing DPL-generated PDF file.

Add support for XRechnung compliance.

Image duplication after import-export when working with images that have different streams but same metadata.

Add support for Encryption Algorithm 7.

JavaScripts collection of RadFixedDocument is not cleared by StripJavaScriptActions export setting.

Unable to obtain the value of incrementally updated fields. The original value of the fields is resolved instead.

Grid PDF Export fails on Blazor WASM with CryptographicException: MD5.

Root Cause: 
PdfExportContext.CreateDocumentId() calls System.Security.Cryptography.MD5.Create(). MD5 is not available in the .NET WASM runtime by default and throws CryptographicException.

When processing PDF documents on the NetStandard target, glyph positions become incorrect after performing an import-export operation on documents that use non-embedded fonts.

Here is a sample structure of the signature:
