crop whitespace from an image
CROP(FILENAME,APPEND,MARGIN) is the full calling form. APPEND and MARGIN are optional inputs.
CROP('filename.ext') crops the image in the file and saves it using the original filename, overwriting the old image. The extension (ext) can be anything IMREAD supports.
CROP(directory) crops all images in a directory.
If APPEND is 1, CROP saves the cropped image as 'filename_crop.ext' in the same directory as the original.
MARGIN sets the margin width in pixels (default is 10).
Example: crop('C:\MATLAB7\toolbox\matlab\demos\html\cruller_01.png',1)
Requirements: your FIND must allow the 'last' option (version 7+?)

Johan- it shouldn't change the colors. Can you give more details or an example file?
Very helpful but does anybody know why it changes the colours of the picture ?
Very useful. Works like a charm.
Nice job, thanks very much.
I tried savefig but it doesn't crop, this one works great! Keeps me from manually cropping every time with another software
Works very nice, thanks.
Thank you, thank you, thank you!
very helpful, thank you
I wish I had found this earlier. This could have saved me manually cropping about 300 images already, but atleast still saves the next 700.
Wow! This just saved me a wealth of time, Thank you so much!!! No more opening each image one by one in Picture Manager and manually cropping
very usefull, Thanks
Great little *.m file!
Modified it a bit, but more-or-less ready to go.
Thanks a bunch!
Saved me pulling my hair out trying to work this out!
