When saving a PDF document containing dotted or dashed lines as a XPS file or as a DrawingImage, the dotted/dashed lines are converted and displayed as solid lines instead of the dotted ones.
The same goes for printing.
When saving the PDf document as PDF file and opening it with Acrobat, the lines are displayed correctly.
Strange enough, this does only occur when using the WPF libraries (i.e. Spire.PDF.dll version 4.5.3.2041 or Spire.PDF.WPF.dll version 4.5.3.2240).
The WinForms libs (.Net4.0) do not seem to have this error. Why is that?
