When I try to export... PNG works, XML works, but Visio and PDF fail. In all cases I am using a Windows SaveFileDialog, and the same diagram, but it isn't a single diagram that fails, it seems like all of them.

The PDF Export gives this:

System.TypeInitializationException: The type initializer for 'MindFusion.Pdf.Globals' threw an exception. ---> System.ArgumentException: The path is not of a legal form.

   at MindFusion.Diagramming.Wpf.Export.PdfExporter.Export(Diagram diagram, String filePath) 

I'm using a windows SaveFileDialog to get the path... so I know the path is valid. Even if I try to save directly to "C:\new.pdf", it fails claiming the path is not of a legal form.

The Visio Export gives this error:

System.IndexOutOfRangeException: Index was outside the bounds of the array.
   at MindFusion.Diagramming.Wpf.Export.VisioExporter.Export(Diagram diagram, String vdxPathName) 

I have no idea what index it claims is outside the bounds.

Empty String.

Our components are all loaded on the fly via byte array... we aren't going to have an Assembly location.

We also won't ever have an Application, since we don't use the Application framework.

The PDF Viewer just builds a font cache relative to my assembly location. That doesn't really seem necessary. Can't this be changed to let me pass in a shared font cache folder or use Isolated Storage or something instead?

That said... I hacked our code to load your components from file instead of byte array and it fixed the PDF Viewer. I might be able to get a workaround, but it'd be highly undesirable.

The Visio Export apparently requires a template... I'll have to figure out how to distribute that I guess... But at least I can point at a location for it.

Thank you. I'll look forward to that.

Two side notes about the exports... Is there a way to export only the parts of the diagram that are... populated? It appears a large chunk of our diagrams are unused, using like the 10% in the top left corner. This makes the export mostly blank, so we in the case of PNG, and PDF we get a hugely blank image/document with a teeny tiny diagram in the top left.

The Visio export also holds the font settings from the diagram. Since ours is millimeter sized, the font size is like 2.4, which in Visio is illegibly small.

The Visio export looks fine (minus the above issues) in full Visio. But the free Visio Viewer from Microsoft loads the diagram and it the nodes overlap, the links don't connect correctly... Is that a known issue?

ResizeToFit works brilliantly. Thanks.

Okay, at least I have a response for Visio Viewer questions, should they arise, thank you.
