Hi All

Is there a way to remove the white/anycolor border that contains a logo with -trim?
or alternatively,
can I detect the dimensions of a Photo and create a mask to cover the border/logo?

I am new to image magick so please be gentle if this has already been covered, I did search.

Thank you all so much.

I am using the latest OSX 10.10.5 with the latest IM from Homebrew but the code it will run on Linux.

It is easy to remove that top using -fuzz XX% -trim +repage. But the bottom is harder because of the text. Since the text is light gray, this seems to work with a large fuzz %. The fuzz percent allow the trim to consider colors that vary from constant by that percent.
Otherwise, one would need to crop the left column of the image and use txt: output format to the terminal to see where the first and last transition from white to other than white occurred, then you could compute the crop coordinates and use -crop or -shave to remove the top and bottom.
