Re: [libreoffice-users] exported PDF file size

Hi :)
If the quick test with gifs seems to be fairly good you might be able to 
clean-up some of the images a  bit to remove the wobbly waves that jpg format 
introduces.  Getting back to sharp edges and distinct corners, removing 
speckling can get file-sizes down a little bit more but the main change happens 
with the change of format ime.
Regards from
Tom :)
