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.

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" />

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

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.

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.

Default DctDecode implementation uses System.Windows.Media.Imaging.BitmapImage in order to get the image pixels. However, when the image uses some complex colorspace (for instance Separation based on CMYK) the BitmapImage is initialized with a different format and we use System.Windows.Media.Imaging.FormatConvertedBitmap in order to get the pixels in CMYK colorspace. There seems to be some issue with these calculations as the resulting image has incorrect pixels.

WORKAROUND: You may inherit DctDecode class in order to implement custom decoder and call DecodeWithJpegDecoder method from the base class as mentioned in the note of this documentation article:

http://docs.telerik.com/devtools/wpf/controls/radpdfviewer/customization-and-extensibility/customize-pdf-rendering

A sample implementation of these custom decoder may be seen below:

public class CustomDctDecode : DctDecode
{
    public override byte[] Decode(PdfObject decodedObject, byte[] inputData, DecodeParameters parms)
    {
        return DecodeWithJpegDecoder(inputData);
    }
}

When annotations have annotation flag Print they should be visualized when printing the document. Usually, Widget annotations have such flag and currently RadPdfViewer does not print them at all.

NullReferenceException is thrown when importing a document with AcroForm referencing a missing object for fields collection. This is a regression as the same document will be imported without a problem in previous versions of RadPdfViewer as the AcroForm object would be entirely skipped.

The current implementation relies on the graphic state color to be always SolidColorBrush. However, it may be other color type and InvalidCastException is thrown. This results in missing content.

Decode array for image masks with DeviceGray color space is not respected, and always the default array of [0 1] is used for visualization. When the mask is encoded with [1 0], the mask is applied inversed, making the wrong pixels transparent. This may lead to images becoming invisible.

Due to excessive memory consumption when decoding images, OutOfMemoryException can be thrown when viewing documents with large images inside them. 

Workarounds: 
- Set ExtensibilityManager.MaxImageSize = null. This will skip one resizing step, and could be beneficial in documents containing few large images.
- Use 64-bit process for the client application. This allows the process to consume much more memory. Note that starting 64-bit process while debugging can be tricky, as described in this blog post: https://weblog.west-wind.com/posts/2016/Dec/19/Visual-Studio-Debugging-and-64-Bit-NET-Applications.
