Ive just been trying to crop a series of pngs(animation), there are about 400 frames so I created a photoshop batch process to take the canvas size from 569x320 to 512x320 but when I compare the output images to the input images there is very noticable blur! this is really wierd as I thought the image would not be…
nope I was using canvas size to crop at the beginning but it seems canvas size does not actually physically crop but slightly resamples but it only does this when used on a batch process, it doesnt blur/resample at all when used in photoshop on a single image.
thanks vig might give this a go tomorrow, yeah crop(canvas size) really shouldnt resample or blur an image at all but when I ran a canvas size action on a folder it blurred all of the images. Your method of doing it with a selection sounds like it might work but really this must be a flaw/bug in photoshop.
