When a pdf/a compliant document is opened in Adobe, there is a bar saying that the document is compliant with the standard. Expose such functionality in PdfViewer as well.

The current implementation relies on valid cross-reference table offsets in the PDF documents so that PDF objects are easily found and parsed. However, a mechanism for importing documents with invalid cross-reference table offsets may be implemented.

The attached project shows how to repair such documents.

An implementation of JPXDecoder should be created to allow the decompression of data encoded using the wavelet-based JPEG2000 standard.

Guidelines of how to provide a custom implementation of the JPXDecode filter can be found in the Customize Rendering section of the documentation and a sample implementation can be found in the SDK examples.

Add support for interactive forms based on the Adobe XML Forms Architecture (XFA). XFA specifies an XFA resource, which is an XML stream that contains the information of the form. The format of an XFA resource is described in the XML Data Package (XDP) Specification. The XFA resource provides most of the information about the form; in particular, all form-related events such as calculations and validations.

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."

The rendering of images with size ~5000/6000 and BitsPerComponent=1 is time-consuming. The scenario is optimized in terms of memory but would be nice to increase the performance as well.

A similar scenario is not defined in the PDF specification but the widgets can be rendered as read-only fields despite the fields associated with them are missing.

RadPdfViewer can not find startxref keyword at the end of a document if the document contains many zero bytes at its end. NotSupportedException is thrown with "Startxref keyword cannot be found" message. 

Workaround: Trim the ending zero bytes before loading the document to the PdfViewer. This is currently noted in the WinForms KB article:

Currently, we use System.Windows.Controls.TextBox for editing both TextBox and CombTextBox field types. We should implement CombTextBox editor which would allow having spaces between characters during the editing process.

At this point, the Print() method allowing the customers to silently print a document uses the PrintableAreaWidth and PrintableAreaHeight properties of the print dialog, which are read-only and cannot be changed through the API. Consider changing them with PrintTicket.PageMediaSize.

We should also consider the scenario when the client needs to print a smaller PDF page on a bigger page size. For instance, A5 page to be printed on an A4 sheet without scaling the content.
