Diagram: Support exporting of large Diagrams
Currently large diagrams are hard to export with good quality because of the memory limitation in WritableBitmap when the DPI is increased.

 -- One option is to use BitMapCacheBrush (discussed here http://www.telerik.com/forums/low-resolution-using-exporttoimage-on-big-diagram)

 -- Another option is to export multiple images of the diagram which cover it all. Then possibly combine these pictures into one.

 -- Also , you can try increasing the operating memory of your Visual Studio

Please check out the following SDK sample which addresses this scenario:

Currently large diagrams are hard to export with good quality also because of the memory limitation in WritableBitmap when the size of image is increased leaving DPI at 96d. (default)

In attachment the same shape, with default dpi, exported on small diagram (300 x 150px) and on a big diagram (6100 x 6100 px) and repro sample started from github xaml-sdk repository.
