need help with simple cropping and saving out images

[supercali]

can someone show me what to do for this task?

I am looking over this program first time and I cant tell what I should do
repaige shave crop? Almost two many options so I cant tell what i need.

I just have an image called image.bmp that is 512x 512 and I want it chopped/divided and saved in 4 pieces 256x256 that are named 1.bmp, 2.bmp, 3.bmp, and 4.bmp as though reading from left to right.
How might I do this in one command line.
thanks for any help.

Try:

Code: Select all

convert image.bmp -crop 256x256 %d.bmp
