Hi Spoorthi
Another angle:
I've found SVGs to be MUCH MORE efficient in terms of space usage. Try to see
if you have those logos in SVG format instead and see if it helps.
The added bonus of doing this is that image still looks nice even when the
end-user is using the zoom function when looking at the PDF document.
SVGs cannot do everything that say JPEG can. For example Apache FOP doesn't
have support for SVGs that use gradients. However, I've found that most
corporate logos aren't that advanced and they typically work well with SVG
format.
Give it a try.
For example something like this:
<fo:external-graphic .... src="../my-company-logo.svg"/>

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). 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!

- 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 ;-)

Hi Team,
We have a requirement to reduce the size of the PDF size from
200Kb(approximately) to as less as possible. There are 5 images in the PDF that
I am using.
PDF size without images is coming up to 40Kb. Each Image size(jpegs): CCX logo-
60Kb, 3 small images: 18kb each, SMS logo - 50Kb approximately.
The PDF size is increased as mush as the image size is. Is there a way for us
to optimize the image size or the PDF size in FO?I have already set this
property: </disable-srgb-colorspace>true</disable-srgb-colorspace>
Please let me know if there are any techniques to achieve this. Has there been
any enhancements done in the FOP 2.0?
Thank you,Spoorthi
