Thanks for this great program.
Is possible to resize a picture giving only one dimension? I'll explain: If I need a picture of fixed width, but with height undefined, how can I resize the picture with proportions constrained so the picture is fixed width?
For example: I have a site that accept pictures as wide as 800 pixel. I have pictures of all sizes and I have to resize on that fixed width. I don't care about the height of a picture, because my website can scroll down but not left/right.
It can be possible to achieve? Because as far I've tried, you must specify width AND height.
Thanks to everybody.
