Resolved. I walked through the Main class code and replicated the steps.
Part of my problem was I was trying to use the java code posted earlier instead of the userconfig.xml FOUserAgent ua = fopFactory.newFOUserAgent(); TIFFRenderer renderer = new TIFFRenderer(); renderer.setUserAgent(ua); renderer.getWriterParams().setCompressionMethod(TIFFConstants.COMPRESSIO N_CCITT_T6); ua.setRendererOverride(renderer); The above will throw the exception I had been seeing. Thanks for all the help! I'll see what I can do to contribute to the group. -Josh -----Original Message----- From: Jeremias Maerki [mailto:[email protected]] Sent: Wednesday, July 14, 2010 2:49 AM To: [email protected] Subject: Re: XML to TIFF CITT conversion - aid requested Hi Joshua Make the config file: <fop version="1.0"> <renderers> <renderer mime="image/tiff"> <compression>CCITT T.6</compression> </renderer> </renderers> </fop> ...and you're there. As for your other question, you can do something like: FOUserAgent ua = fopFactory.newFOUserAgent(); TIFFRenderer renderer = new TIFFRenderer(); renderer.setUserAgent(ua); renderer.getWriterParams().setCompressionMethod(TIFFConstants.COMPRESSIO N_CCITT_T6); ua.setRendererOverride(renderer); ...but the above only applies to FOP 0.95 or later, I think.
