pdf file size

[Miki Dovrat]

Hi,

Can I give lyx (or imagemagick convert through lyx) or some other latex 
package an option to resample all graphics in a certain resolution to 
reduce the pdf file size?  convert has a -resample option.

I would love to do it "on the fly" without actually producing lower 
resolution images on disk, and pointing to them. Can I run a python 
script in the lyx tmp directory by lyx, or any such solution?

I know adobe acrobat does this on the output pdf for $300. Doing convert 
on the pdf ruins the text as well.

Thanks

Miki
