I have a Google Docs drawing that is a small scheme. However, this small scheme is surrounded by a lot of background that occupies a lot of useless space.
I do not want to remove the background manually because I may need the extra space in the future.
I know Latex has a lot of image packages, so I was wondering if there is some package that I can use to automatically detect that useless background and crop my image so I do not have all that white space around it.
I know some of you will suggest the external tool pdfcrop. I have experimented with it, but it does not crop the image at all.
