convert -extract example [SOLVED]

[ZiTAL]

Hi, I'm trying to extract a part of image, i'm trying with this command:

Code: Select all

convert -extract 112x122+77+77 input.jpg output.jpg

to extract 112x122 rectangle in x 77 and y 77 position, but the image generated is the same as original.

I'm looking examples in internet but i don't find anything.

Thanks for all.
