image-crop img x y width heightprocedure
image-crop! img x y width heightprocedure

Crop img. The x and y parameters indicate the upper left pixel of the new image. The width and height parameters indicate the size of the new image. Returns #f on failure.

Note: This procedure will return an image of the requested size, but with undefined contents if you pass it arguments that lie outside the image! I am still unsure if this is a bug or feature.
