Implement functionality allowing to specify that when a table is split on multiple pages, a specific row should be shown on each page.

Workaround: in the attached demo projects.

Currently, similar scenario may be achieved by converting Tiff images to BitmapSource and inserting them to RadFixedPage as images by using FixedContentEditor.
Note: A sample approach how to achieve such functionality is demonstrated in the Converting Multi-page TIFF Images to PDF KB article.

The CropBox is currently not supported by RadFixedPage class and is not preserved on an Import-Export scenario with PdfFormatProvider. CropBox is also not supported by PdfPageSource class and it is not preserved by using PdfStreamWriter as well. This property should be implemented in both scenarios.

By specification the last line of the file contains only the end-of-file marker, %%EOF. When importing document with missing EOF, InvalidOperationException: 'Stack empty', is thrown.

The case is invalid according to the specification but all readers manage to open the document and allow editing its fields. The document can be also opened in RadPdfViewer but without the fields and the widgets.

Exported protected document containing SignatureField can not be opened even if the correct password is used. The same behavior is reproduced with empty document (without pages).

When documents are exported to PDF, the creation date and modification date are not expected, or, when the time zone is with negative offset, the documents are invalid (detected by validation tools).

Support conversion of XPS documents to PDF using RadPdfProcessing.

Some customers need to export a single page of the PDF document to plain text. Expose such a possibility so the customers don't need to export the whole document.

Stencil color has to be preserved for images with ImageSource when ImageMask property set to true. Not preserving it results in wrong colors (for instance the image may be visualized as a black rectangle).

Available in R1 2019 Official Release Version.

The tj operator is responsible for drawing text content. When such operator is left empty, the import throws NullReferenceException because of the missing operands.

Available in LIB Version 2018.3.1022.

This operator modifies the current clipping path by intersecting it with the current path, using the even-odd rule to determine which regions lie inside the clipping path.

Available in R3 2018 SP1 release.

 This is content stream operator that is used to close, fill and then stroke a PDF path geometry.

Available in R3 2018 SP1 release.

This type of fields is currently not supported: https://feedback.telerik.com/Project/184/Feedback/Details/249205 . However, the fields can be skipped and the other content can be imported without throwing an exception.

Fix available in R3 2018 SP1 release.

When the string contained in a PdfHexString instance is empty, invoking ToString() leads to IndexOutOfRangeException.

Available in R3 2018 SP1 release version.

A font descriptor can be used by several fonts. However, when first a TrueType font is imported, later trying to import a Cid font leads to InvalidCastException with the message: "Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.Fonts.FontDescriptor' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.Fonts.CidFontDescriptor'."

Fix available in R3 2018 SP1 release.

The hierarchical document structure is a means to describe the PDF document structure, which is currently not supported. See 10.6.1 Structure Hierarchy on 856 page of the PDF specification for details.
This document structure is an alternative to the standard PDF structure and most non-Adobe software does not support it.

The document might have been created with Adobe software like Adobe LiveCycle Designer. Very often the document contains some fallback text in the standard PDF structure like:
"Please wait... If this message is not eventually replaced by the proper contents of the document, your PDF viewer may not be able to display this type of document."
"The document you are trying to load requires Adobe Reader 8 or higher. You may not have the Adobe Reader installed or your viewing environment may not be properly configured to use Adobe Reader. For information on how to install Adobe Reader and configure your viewing environment please see  http://www.adobe.com/go/pdf_forms_configure."
"For the best experience, open this PDF portfolio in Acrobat X, Reader X, or later."

CMYK color may be set using SCN, scn, K and k operators.

Available support for import of CMYK colors in R3 2018 Official Release.

In this case, we should use a default alpha source value which is the opacity source.

The signature field preserves information about the time of signing through the TimeOfSigning property of Signature.Properties. However, the DateTime object doesn't keep info about the time zone the document has been signed in. Some customers need to obtain this information.
