CROP gets rid of whitespace around an image

| Watch this File

File Information

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+?)

MATLAB release MATLAB 7.0.1 (R14SP1)

Johan- it shouldn't change the colors. Can you give more details or an example file?

I tried savefig but it doesn't crop, this one works great! Keeps me from manually cropping every time with another software

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.

I improved the input checks and comments. Code now handles transparency in .png files. MARGIN is now an input.
