For example, when some PDF file has uncompressed contents we may import it and apply better compression to the stream objects. Ensure that all the content inside the document is compressed.

Currently, we have the following options for PDF export optimizations:

• ImageQuality
  

  pdfFormatProvider.ExportSettings.ImageQuality = ImageQuality.Low;

• ImageCompression
  

  pdfFormatProvider.ExportSettings.ImageCompression = new ImageFilterTypes[] { ImageFilterTypes.FlateDecode };

• StreamCompression
  

  pdfFormatProvider.ExportSettings.StreamCompression = new StreamFilterTypes[] { StreamFilterTypes.FlateDecode };

• FontEmbeddingType (Q2 2024)
  

  pdfFormatProvider.ExportSettings.FontEmbeddingType = FontEmbeddingType.Subset;

  We introduced an option of exporting subsets of True Type Fonts (*.ttf) for the .NET Standard version of the library.

The Indent property of Table is not respected by PdfFormatProvider.

Add support for array formulas (CellFormulaType "array"). These formulas can accept as parameters and return results containing whole arrays (one- or two- dimensional) of data. In MS Excel, such formulas are inserted with CTRL + SHIFT + Enter, and visualized enclosed with curly brackets ('{' and '}'). 

Text frames are paragraphs of text in a document which are positioned in a separate region or frame in the document and can be positioned with a specific size and position relative to non-frame paragraphs in the current document. More information about it is available in section 22.9.2.18 ST_XAlign (Horizontal Alignment Location) of Open Office XML.

When importing a document containing an invalid PDF object dictionary key an exception is thrown.

When importing a document with button field with missing type, an error occurs.

Workaround: Handle the exception: https://docs.telerik.com/devtools/document-processing/libraries/radpdfprocessing/features/handling-document-exceptions 

Add support for creating Tables and applying tables styles (predefined ones or custom).

This would allow creating documents with preferences such us HideToolbar, HideMenubar, FitWindow, PrintScaling and all other viewer preferences specified in PDF format specification.

The method should create deep copy of  the current page.

PdfProcessing: Handle merge of documents containing fields with the same invalid name.
