you set the DPI in the print driver - in Windows XP,
for Adobe, go to the Control Panel, open the Printers, right-click on "Adobe
PDFWriter", then select properties. Click on "Preferences", "Page Setup",
then select the resolution in the "Graphic" section.
but if you do your design just for online purposes usually 72dpi is ok for .pdf images

Hopefully that makes sense to somebody: if not, feel free to say! I'm looking to do it with PHP in a Linux environment. I have tried with pCOS but apparently it's not possible, though I'm happy to be corrected. ????: NamePros.com http://www.namepros.com/programming/485167-dpis-of-images-in-pdfs.html
If I need to pay for a library, I'm happy to do so, so long as the price, support and reliability are right.
Thanks...
