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

Introduce an API for Cloning RadFixedPages.

This is preserved in the xml once saved from MS Excel:

At this point, XlsFormatProvider doesn't support images and they are not imported into Workbook while reading an .xls file.

Add support for PDF Portfolios.

At this point XLS import of SpreadProcessing does not have support for notes/comments.

Add support for ShadingType 1.

Add support for superscript and subscript font effects for cell formatting. Currently, this is not supported by the model and is omitted on import.

Expose internal GrayColor object.

XlsFormatProvider: Add support for hidden rows.

Add support for strikethrough font effect for cell formatting. Currently this is not supported by the model and is omitted on import.

PdfFormatProvider: Export accessible PDFs.

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.

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

With the current implementation, the compression setting is omitted:

• streamWriter.Settings.StreamCompression

Add support for TRANSPOSE function.

Add support for AutoTextList field.

Add support for VML shapes.

Related: Add support for Shape Group.

Shape Group is used to collect shapes and groups so they can be positioned and transformed as a single unit. A group contains group, shapetype, shape, pre-defined shape - arc, curve, image, line, oval, polyline, rect, roundrect - and lock elements.

When the object is serialized out as XML, its qualified name is v:group.
