Trim with limitations

[novito]

Hi guys,

I am using the trim function in order to get rid of a background surrounding a product image. However, the trimming sometimes cut too much, and I would like to know if there is a way of giving trim the option to say, give 2px of margin from wherever you were gonna cut to.

I haven't been able to found that on the docs, so I thought you guys could have any ideas.

Thanks

You can get the trim bounds by

identify -format "%@" yourimage

put that into a variable or separate into the needed variables. Then add whatever extra you want. Then use -crop WxH+X+Y +repage to crop it with your modified trim variables for W,H,X,Y.
