Personally I use Apache FOP for some projects - but I am not quite an expert when it comes to Java…

As far as I understand you may want to adjust the image resolution/compression to shrink the size of the files used in you FO - but I am not sure if this can be done automatically using a different image handling subsystem (https://xmlgraphics.apache.org/fop/0.95/graphics.html <https://xmlgraphics.apache.org/fop/0.95/graphics.html>). Changing the color space may only affect the color profile/representation, but I don’t think this will preprocess the image size at all (sRGB is just a smaller gamut than Adobe RGB and RGB) - you may just get a different representation of colors outside the given gammut!

From my perspective, it’s the same thing as placing an image in a layout software: the image will be used „as is“. Only when it comes to write the PDF you may have the ability to „donwsample“ all images to a given resolution relative to the size in the layout…

- One solution might be to adjust the images to a proper size and compression accordingly to the layout
- Alternatively you may „optimize“ the PDF for internet use: resample, compress and remove duplicates (images used multiple times)

Just a few ideas which may help if there is no native solution in Apache FOP ;-)
If there is no working solution in FOP, I may send you a link to a freeware to optimize the final PDF

The FOP guys may forgive me if I am completely wrong ;-)

Best,
Frank
