Vertical lines with small length and big thickness are drawn as short horizontal lines with big StrokeThickess. This results in rendering them as big squares, which can hide parts of the content.

When an image is actually consisting of vertical sequence of smaller images, sometimes white horizontal lines appear between the smaller images.

When clicking on link annotations pointing to destinations in the document, and the "Fit one full page to window" mode is activated, the document is not scrolled exactly to the destination.

The issue can be reproduced only in Single Page Presenter mode and when the Top and Left values of the passed parameter are greater than 0.

The problem can also be observed by invoking directly GoToDestination method, as the problem is inside it.

With the current implementation, it takes seconds to decode and display JPEG with several megapixels (for example size 4000 x 2000 pixels). The memory consumption when decoding such images also needs improvements.

Workaround: Custom DctDecode filter may be implemented and registered in RadPdfViewer. The attached demo shows how this may be achieved by using BitmapImage class to decode the JPEG images instead of the default RadPdfViewer's JpegDecoder.

The issue is caused by memory optimization that requires loading page content only for the visible pages. 

In order to fix the issue and still benefit from the memory optimization, we are introducing setter in FixedDocumentPresenterBase VisiblePages property. Now this property needs to be set each time the visible pages are changing in custom presenter implementation. Setting VisiblePages ensures that all visible pages content will be loaded correctly.

Currently, when we parse inline image dictionaries we rely on the assumption that the colorspace will be PdfName. However, there are files with complex colorspaces that are PdfArray and InvalidCastException is thrown. All the content after this exception is lost and not visualized by RadPdfViewer.

Even small documents (~30 kb) containing images encoded with CCITTFaxDecode filter can take about 10 seconds to be opened. In 2014 Q1 SP1 such documents load faster.

As a result, the glyphs are not measured and positioned properly. The issue applies to the TrueType and Type1 fonts.

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);
    }
}

Instead, we should not visualize them and they should not be interactable with the mouse.
