ColdFusion: How could can crop white space margins from images?

I'm generating screenshots using a html-to-image tool, however the generated images have excess white space around them. Is there a straightforward way in Coldfusion to crop the image to remove white space? .. essentially move the margin of the image to remove redundant white space so that the image doesn't appear padded with white space?

Please don't recommend a different html to image tool since i would like to know how to do the above for other cases.

Any ideas? Many thanks in advance.
