Can I remove border that contains an image

[snaplash]

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.

Code: Select all

convert image_full.jpg -fuzz 70% -trim +repage result.jpg

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.
