Implement functionality to support scenario when a document which already has a signature to be signed again or add two or more signatures.

Handle the import of documents with Associated Files (/AF) elements whose content is set to null.

Handle the import of documents with null elements in the Associated Files (/AF) collection.

Introduce support for UnShrinking - Method 1.

This type of action is currently not supported and a NotSupportedActionException is thrown when accessing such an object.

These exceptions can be handled using the Handling Exceptions mechanism.

Export AdditionalActions of the page when merging pages with PdfStreamWriter.

When importing an existing document which contains a GoToR action, we should preserve the action even after exporting it.

Currently, the SkiaImageFormatProvider considers the RadFixedPage.Size when creating the image. If the RadFixedPage.CropBox is specified, the developer can control what rectangle of the page to be displayed/printed. However, it is not considered when exporting to an image. Improving the SkiaImageFormatProvider to respect the CropBox as well will give the opportunity to crop just a certain region of the PDF page and save it as an image.

This property should work similar to PreferredWidth cell property but in vertical direction.

Implement support for adding barcodes to a PDF document.

Optical character recognition or optical character reader (OCR) is the electronic or mechanical conversion of images of typed, handwritten, or printed text into a machine-encoded text from a scanned document.

Add support for Named Actions.

RadPdfProcessing currently supports interactive forms whose data is defined directly in the document. To preserve them when importing and exporting documents, add support for import-export interactive forms based on the Adobe XML Forms Architecture (XFA).

From PDF 2.0 the XFA forms are depreciated.

An ArgumentNullException is thrown when importing a document with a missing required MediaBox operator in the Page object ("ArgumentNullException: 'Value cannot be null.")

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.

This will enable printing with the following printing options: 

- Fit Sheet on One Page

- Fit All Columns on One Page

- Fit All Rows on One Page

- Custom automatic scaling


A possible implementation of a similar behavior is to use the PageSize property of WorksheetPageSetup and subtract the corresponding margin values (from the Margins property) from the width to calculate how many columns are fitting in some particular page size with 100% scale factor. 

Available in R2 2018 Official Release version.

Expose a DocumentUnhandledException PdfExportSetting when converting a RadFlowFlow to a RadFixedDocument document.

Matte color is used for preblending images with some background color, using the SMask. Matte color is specified using the optional 'Matte' entry for the SMask object.

See PDF 1.7 specification, page 554-555:

Matte
array
(Optional; PDF 1.4) An array of component values specifying the matte color with which the image data in the parent image has been preblended. The array consists of nnumbers, where n is the number of components in the color space specified by the ColorSpace entry in the parent image’s image dictionary; the numbers must be valid color components in that color space. If this entry is absent, the image data is not preblended.

 PdfProcesing: Add support for Transparency Group XObjects

Sometimes customers need to create documents using the CMYK colors to meet specific requirements for printing. Expose such functionality in PdfProcessing.
