Re: image rotation

One file has an embedded profile, and the other doesn't. So how are you comparing them? i am not sure i am understanding what you mean... anyway i used the syntax compare file1.jpg file2.jpg diff.jpg... It may look black, but it isn't, even using just 8-bit Gimp, whether or not we convert them to t...

Re: image rotation

hi. i think i solved the problem using GIMP. I used layer mode difference applied to the two images and the result is total black. so i think there is no rotation. i have just one more question. GIMP says that the two images are identical, that is the pixel values are identical. But imagemagick COMP...

image rotation

hi,
i use imagemagick 7.0.7.21 for windows
i should verify if an image was rotated of an angle from the original one. the two pics may have different quality because of manipulation. my question is: is it possible to veryfy if the manipulated one was rotated?

thanks
