Hi,
I'm using PDFBox from a C# app via IKVM. Stripping the text out of a
PDF works great, but I've been unable to render a page as an image.
I'm using PDFBox 0.7.3 with IKVM 0.40.0.1; I built my own FontBox and
PDFBox DLLs as outlined below [1]. My test script fails with a
NotImplementedException [2].
Does anyone know if I should expect PDFBox + IKVM to be able to
generate images of pages? If so, does anything jump out as
particularly wrong about my configuration, or do you have any pointers
to a happy configuration?
Thanks,
-Patrick

FTR, when I tried the same test with the DLLs that ship with PDFBox
0.7.3 (linked against GNU Classpath), I get an
