FYI, for anyone using PDFBox vs 0.8.0 via .Net... After some trial and error I discovered that IKVM vs 0.38.0.2 does not support PDFBox image placement. It returns an error "Not Implemented".
However, IKVM vs 0.40.0.1 does support the Java java.awt.image library a little better. It takes a little bit of a re-write of the build.xml file because the new version has completely different .dll file names. Rob Bradley
