Re: Changes in pdf tiff compression configuration has no effect on size of pdf generated
If the image is CMYK and you get gray scale output it means the image had no color profile embedded. If you embed one FOP should convert it to RGB unless you have an ImageIO library that can handle CMYK.

Re: Changes in pdf tiff compression configuration has no effect on size of pdf generated
My original image is in fact grayscale, but the grayscale original and the rendered grayscale look different, that's the issue. In that case, is it related to CMYK or something else? 2014-01-29 Luis Bernardo lmpmberna...@gmail.com If the image is CMYK and you get gray scale output it means the image had no color profile embedded.

RE: Changes in pdf tiff compression configuration has no effect on size of pdf generated
Yes Registar man is correct ! if your output is pdf, you can't use the renderer/tif I mentioned earlier. However, you can remove the pdf image compression by using something similar to ( according to what your ultimate goal is ) : renderer mime=application/pdf filterList type=image valuenull/value /filterList/renderer /renderers By using it on a example pdf with a simple tif (with LZW comp), the pdf's size went up from 40 kb to more than 600kb.Thanasis Date: Tue, 28 Jan 2014 12:52:12 +0100 From: szea...@gmail.com To: fop-users@xmlgraphics.apache.org Subject: Re: Changes in pdf tiff compression configuration has no effect on size of pdf generated Hi!

Re: Changes in pdf tiff compression configuration has no effect on size of pdf generated
Hi! So, I think the FOP working mechanism is: By rendering the output it uncompress and rendering the images into the document. Because of you need to define the PDF settings i sent before for recompresing used images in the pdf. I don't use these settings ever, i just think it working as i wrote above.

Hello, Which Fop-version are you using (!.0 1,1 trunk etc)? Can you provide the configuration and xsl-fo file you have been using so far to generate the pdf?
