RE: TIFF image rendering in pdf is lossy
Angus, let me know if you need any more help with this - I was the "culprit" who submitted the support for the CCFFilter to FOP. We needed it as we render lots of incoming faxes into PDF. But they are Group 4 encoded.

Re: TIFF image rendering in pdf is lossy
It would seem that the real issue is that some code I was using was doing an implicit convert of the tif image to jpeg before the transformation took place. Sorry to bother.

RE: TIFF image rendering in pdf is lossy
Angus, have you got JAI (Java Advanced Imaging) in your FOP environment (see http://xml.apache.org/fop/graphics.html)? If not that may be the problem as the TIFF support relies on the presence of JAI. If JAI is not available it defaults to using JIMI and that again will DCT encode your images as JIMI has only very limited support for the TIFF format.

TIFF image rendering in pdf is lossy
FOP 0.20.5rc2 ISSUE: TIFF image rendering in pdf is lossy. QUESTION 1: Is this a configuration item? QUESTION 2: How can I, as a user, resolve this issue. Comparison of tiff image to rendered image in pdf. PDF shows marked degredation. PDF contains tag: /DCTDecode - indicates lossy compression Using a faxed tiff image.

Image Rendering Problem.
Hi All, I am using Apache FOP to generate pdf file. The pdf file is around 50-55 pages long. Each page has an Image( which is very big 100-150k).This is scaled down by fop. It really takes lot of generate pdf. Somebody on the fop-user list suggested me to scale down the image before feeding to image. Could this help me. or any other solution. Also can you please suggest me some java library( or any other efficient software) to scale down image. Any other suggestion?
