Remove two surfaces of image

[Thom]

Hello,

I have 300+ images of the same format below, and I want to remove the grey surfaces of the picture, so the final image need to be the blue surface with the measurements of 720x550 px.

Can someone help me with a commandline script to do that.
All the images are in the same folder.

Thanks in advange!

Are the gray and blue areas always the same size and color? Are they always labeled with the sizes? What version of IM are you using (convert -version) and what platform?

convert UX8qK.png -crop 720x550+0+50 +repage x.png

Yeah the areas are always the same, but not the same color, but I make it in the drawing so to simplify my question. I am using version "6.9.1--6 Q16" And I am running Windows 8.

Does my command do the job?

convert UX8qK.png -crop 720x550+0+50 +repage x.png

This Works! Great!

Do you know how to convert a whole folder? Thanks!

Yeah the areas are always the same, but not the same color,

snibgo's command should do what you ask

see mogrify at http://www.imagemagick.org/Usage/basics/#mogrify

create a new empty directory, so that you do not write over your existing files, for example test2. Assuming your images are in test1, then

Code: Select all

cd test1
mogrify -path pathto/test2 -format png -crop 720x550+0+50 +repage *.png
