Introduce an API for Cloning RadFixedPages.

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.

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.

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.

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

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.

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

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

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

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

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

NotImplementedException is thrown for GetCapHeight method of CFFFontSource.

When the text is long and AllowScroll is false, the text will be visible, but will be misplaced. The issue is caused by the length of the text because the same field with a shorter text that can fit in the widget's rectangle will be displayed correctly.

InvalidOperationException: 'isContentReleased' is thrown when appending pages with shared image content to a new document using the PdfStreamWriter.

Currently, font registration APIs accept only byte[], requiring callers to load the entire font file into memory before passing it to the library. This can be problematic for large font files, especially CJK fonts, which can significantly increase application memory usage.

InvalidCastException is thrown when importing a PDF with a CR-terminated comment in its /Info dictionary.

Importing the attached PDF throws InvalidCastException while parsing its structure tree. A /Layout attribute sets /BorderThickness to integer scalar 1. ISO 32000-1:2008 allows this value as a number or a four-entry array; a scalar applies to all four edges. The importer handles real values and arrays, but not PdfInt.

Setting PdfImportSettings.IgnoreMarkedContent to true currently skips marked-content containers but still imports the structure tree, so it does not avoid the exception.

Expected: Import integer and real scalar values as thickness for all four edges; preserve four-entry array values. When IgnoreMarkedContent is true, skip structure-tree import while still importing pages.

Using the PdfStreamSigner to set signature Properties like Name, Location, Reason, and ContactInfo is not respected after export.

Incorrect character spacing when importing CID fonts with the same BaseFont and different width tables.
