Text in specific pdf files is not visible in the viewer.

The text is not visualized due to the negative value for font size. 

The linear gradient brush in not displayed on some elements.

On images the gradient is visualized.

 

Zooming on physical devices does not work properly (gets stuck). Same behavior when scrolling and panning the document 

 

When trying to scroll, pan, and zoom, these gestures open the flyout menu, not to the document in the viewer.

Some Shading elements are not property imported which leads to unexpected drawings on the exported (previewed in the PdfViewer) document.

Provide support for lots of image formats when exporting PDF documents.

The glyphs are rendered with additional unexpected lines when a specific custom Type 1 font is used to show them.

For example page loaded event: the purpose of the event to get a callback whenever a page is loaded and the page information is available.

Support for horizontal scrolling the Pdf document in the viewer: 
Horizontal single page (go through the pages swiping/scrolling left and right)
Horizontal multi-page stacked (not possible, go through the pages swiping/scrolling left and right)

KeyNotFoundException exception is thrown when the platform type is MacintoshNonSymbolic and the encoding is WinAnsiEncoding.

A remote go-to action is similar to an ordinary go-to action but jumps to a destination in another PDF file instead of the current file.

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

Implement functionality for visualization of comment annotations.

Currently when the pdf document is loaded, no further changes can be made to it.  We should provide a way (automatically or explicitly through a method) to reload the page after the pdf content is modified.

Provide a way to create a custom layer in RadPdfViewer and allow to add custom objects on top of the pdf document (in a similar way as PdfViewer for WPF).

Error message is: "One or more errors occurred. 
(Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfName' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfInt'.)"

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

Provide a way through UI and programmatically to load password-protected pdf documents in PdfViewer.

Provide the option to integrate the hand signature using the digital signature of the PDF document

Images that have drop shadow effect are not properly rendered in PdfViewer - black background appears instead.

The square annotation type displays a square on the page.

As an effect of this, characters, which are not contained in the StandardEncoding names, e.g. umlauts, are measured with incorrect glyph widths. This leads to incorrect glyph positioning in RadPdfViewer.
