So you do have a job as well...I was wondering...:-)
If you can create an "adaptive" routine that applies the correct "downsampling" for images and leaves text alone then all the better.
I was wondering about the bad text-sharpness ever since I read the Iliad in really bright (sun-)light for the first time wher eis was very visible. I thought it was due to some suboptimal anti-alias thing...
I really hope you and/or iRex will find a way to improve sharpness, page-turn speed and retain image quality (for those who need it) all in one package...and I wish you all the luck you're going to need.
At the moment I really envy you coders out there...but on the other hand...it#s nice to sit back and watch others work...
