I think what they do is just scale according to the original aspect ratio, while I want them to just scale until the content fills 600 x 800 no matter what.
I agree with you, NitroPDF is one of the better PDF handlers. I attempted
to re-scale a scanned image of fine print so as to be readable in one standard
zoom selection on the 7. In the end, I was unable to do this without having
serious render delays on the reader itself. Nitro does a great job at scaling
vector images and texts but I think what you want is a 'global' scaling
at the full aspect ratio level so no white space is left. Short of
re-constructing your entire PDF, you might want to contact the nice folks
at Nitro, I'm sure he can point you in the right direction, if not solve your
issue all together...
Let us know how you do.
