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.
