Extract the specified rectangle from the SPOT image. Most SPOT images are 3000 lines long and 3000 or more columns wide. Unfortunately, the SPOT format only gives the width and not the length. The width is printed on standard error. The default rectangle is the width of the input image by 3000 lines. -

I've had only a limited number of SPOT images to play with, and therefore wouldn't guarantee that this will work on any other images. -  -
