This may result in inversed transparency issue when rendering images with ImageMask.

Fix available in LIB Version 2017.3.1120.

Currently, the implementation relies on the fact that the previous cross-reference value of a stream object is always a stream object. Instead during the cross-reference recursion, we should check on each step whether the previous cross-reference item is table or stream.

Fix available in LIB Version 2017.3.1120.

Before starting to decode big image, try to estimate the needed memory and check if such memory is available using the MemoryFailPoint class. The behavior in case of failure in printing scenarios should be considered carefully.
The user should be able to turn the behavior on and off.

Currently, the Find() method searches from the beginning of the document to its end. Enable the customer to specify a particular range of pages the method should search through.

When a page is rotated its annotations are not positioned correctly. 

FixedDocumentSinglePagePresenter uses simple rendering mechanism using UIElements, which currently has some limitations:
- Layers are not supported, thus annotations and forms are not rendered (even read-only)
- UIElements could be affected (clipped) when UseLayoutRounding property set at parent level, when DPI is different that 96 DPI. 

Workaround: If content is clipped, ensure that UseLayoutRounding is set to false as presenter level:
<telerikUI:FixedDocumentSinglePagePresenter UseLayoutRounding="False" />

In Adobe and Foxit readers, the user can draw different shapes, which are later saved as images in the document.

The images are loaded asynchronously and when scrolling too fast, the loader might fail to load an image if it is bigger.

When users do "copy" operation, add the content to the clipboard in RTF format. This would allow to paste the text along with its formatting in text editors like MS Word.

The appearance of such invisible annotation is not imported property and the viewer is trying to recalculate it in an infinite recursion which causes the StackOverflowException.

Fix available in LIB Version 2017.3.1009.

They are used by the page and the XObjects drawn on it and deal with the overlaying of the colors. These groups are described on page 556 of PdfReference 1.7. 

The UserDict collection is not parsed and the procedures for the operators are unavailable. The exception is thrown while trying to read the font file of the Univers and Univers Bold fonts.

Internally, an ArgumenNullException is thrown, which results in missing content when the document is shown in RadPdfViewer.

This may result in seeing the pattern as a solid color or even not seeing it at all if this color is white and coincides with the background of the page.

RadPdfViewer does not read image resources defined in Form XObject elements.
