[SIP-users] SIP mogrify, crop command

[Tim S. <st...@ur...>]

I recently installed SIP 0.4.0 for Windows on a WinXP machine. 
I am using it with Scilab 4.0.  When I try to use the mogrify
command to crop an image I just get the complete original image
back, e.g.

crop_image = mogrify(in_image,['-crop','20x20']);

where in_image is an 80x80 normalized grayscale image,
crop_image is the same 80x80 image.  I have tried with and
without ! and everything else I could think of.  I also don't
know how to properly specidfy the x,y offset for cropped image. 
The other mogrify commands that I have tried seem to work.  For
example resize works (although I haven't figured out how to
specify an offset there either).  Is there a problem with my
command syntax?
