I have got more than 1000 rectangular images (640x400) with a transparent background that I want to resize (to 600x375) and then copy/paste (centered) in a 600x600 transparent image.
In other words, I want to create 1000 600x600 square images from 1000 640x400 rectangular images without deforming what is drawn in the rectangular image.
Any idea about how to do that ?
Thanks !!!!
