Batch cropping images using Mogrify

The command 'mogrify' can crop multiple images simultaneously. Sample case is below.
mogrify -crop WidthxHeight+x+y        images*.png
mogrify -crop 2796x983+429+327        images*.png
The values of width, height, x and y can be obtained by opening an image in Gimp and selecting the rectangle of interest.
