What's the recommended approach to generating a Preview Thumbnail Image of the fist page of a FlowDocument

Question

I would like to generate a small Preview Image of the fist page of a FlowDocument (imagine a Thumbnail View of a collection of FlowDocuments). Can anyone recommend a good approach for doing this?

Answer 1

You should be able to do this by making your FlowDocument display the first page as you want it to appear in the thumbnail, then pointing a RenderTargetBitmap to the FlowDocument and saving the bitmap to disk. There is some code to do this in this article:
