well at best there is a confusion and different oppinions. to be on the safe side I decided to use multiple of 16, you just use once calculated resolutions for corresponding aspects, that's all. and also I heard oppinions that it doesnt pay to go higher than 640, so... just to be safe - especially that you dont gain much with 704...
ciao
May be I didn't explained me well ... I know my english is horrible.
Not that mine is perfect, but I must admit I don't know what you mean ;) - take resolutions that are dividable by 16 (just to be safe, it doesnt cost that much, see my email for precalculated resolutions) - dont go higher than 640xXXX DS
I don't want the final size 704x..., the final size after crop & scale is 640x... My doubt if in the crop step (previous to scale as was said in this list) I must honored the 16 (or 8) multiple rule or not ...
