Henk I wrote an exporter for JasperReports that can save to WordML
format. This is in Java, no no help with RunRev. But I can tell you
that the information is not in pure imageData format. The
information in WordML is a base-64 encoded PNG or JPEG, or whatever.
Well, even though you decode the information from the WordML file,
now you have a binary representation of a PNG or JPEG, etc., and that
is not in a format proper for imageData, which is an array of 4-byte
integers, each integer representing one pixel. You will have to
base-64 decode the information in the WordML file and then read it in
as if you were reading an image file off a disk, etc. This will
decompress the information that is encoded in the file and then you
can use the result as imageData.
