This exception seems to be caused because the stream is not decrypted correctly and the stream data is corrupted. For instance when the stream is with FlateDecode filter the exception is InvalidDataException with message "Unknown compression method".

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.

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" />
