Top-left corner pixel obviously has a coordinate `+0+0`. To get the X coordinate of right-most pixel I have to use this expression: `+%[fx:w-1]`, Y coordinate stays at `0` of course. Since I already supplied `-fuzz` and `-fill none`, both operations will replace the white background with `none`, starting from two top corners of the image using the supplied fuzziness value. -### Cropping the image +## Cropping the image After we removed background, most of the time we can trim a lot of extra space so that our image size corresponds to its content.
