The are places that prefer PDF's for printing, and we've also been using PDF as a distributable format that "everyone can open". It's very easy on a mac to save as PDF (or go to "print" and save it as pdf from there) but there are no options presented about how things should be stored.
My question regarding images within pdf:
In what format are images stored within a PDF? Does PDF just wrap around the existing file (embedded) or does it convert it to some other format for storage? Is there any image compression (such as jpeg) or data compression (lzw, zip, etc) applied to the image?
