Duplicated page content due to an incorrect caching mechanism.

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.

Add support for ShadingType 1.

 

 

This will allow the import of Tensor-product patch mesh gradients. Currently, importing documents that contain ShadingType 7 results in NotSupportedShadingTypeException.

This type of shading is not supported in the current version and a NotSupportedException is thrown when importing documents containing it.

The exception can be suppressed using the Exception Handling mechanism of PdfProcessing.

A shading dictionary specifies details of a particular gradient fill, including the
type of shading to be used, the geometry of the area to be shaded, and the geometry of the gradient fill. Various shading types are available, depending on the value of the dictionary’s ShadingType entry:

• Coons patch meshes (type 6) construct a shading from one or more color
  patches, each bounded by four cubic Bézier curves.

When using Telerik Document Processing (PdfProcessing) for embedding Factur-X invoices, the produced PDF document is Non‑compliant with PDF-AF / Factur‑X according to the following validator:

When importing a document with an EmbeddedFile without a Subtype value.

Introduce an API for Cloning RadFixedPages.

Implement the Exponential Interpolation Function in PdfProcessing. Currently, NotSupportedFunctionTypeException is thrown with a message "Function type 2 is not supported."

PdfFormatProvider: Justified text alignment is not respected for specific text content.

After merging several PDF documents, some pages are blank indicating the following error:

With the current implementation when exporting a Stitching function all the containing functions are exported as Sampled functions even if they originally have been imported as Exponential interpolation functions, which leads to an increase in the size of the document.

More information can be found in the PDF Specification.

System.InvalidCastException: 'Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfStream' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.MarkedContents.ReferencedObject'.'

Add support for PDF Portfolios.

PDF/A‑4f is a version of PDF/A designed for archival storage that:

• Ensures long‑term visual and structural preservation
• Is based on modern PDF 2.0
• Allows embedded files (attachments) that are also archival‑compliant 

 

Add Write/Export support for XMP core properties. This includes the following steps:

Make Schema Properties Mutable
Implement Schema Serialization Methods
Extend XMP Writer for Serialization
Integrate XMP Writer with Document Export

Expose internal GrayColor object.

When importing a document with many Path elements, the memory consumption could be very high.
