crop empty space around images

Post by tester » 2010-02-27T13:00:32-07:00

Hi,

Is there a way to -crop "automatically" the white border or empty space around the images like e.g. with gimp?
Please let me know how to solve this because I miss the option at the crop manual page :-/

Thanks a lot

also see -fuzz to allow your trim to be less sensitive to slight color variations in the area you want to trim.

see http://www.imagemagick.org/script/comma ... s.php#fuzz

for example,

convert image -fuzz 1% -trim +repage result

The +repage removes the virtual canvas which is the size of the input and makes the output just the trimmed size.

see http://www.imagemagick.org/Usage/crop/#trim

I had an issue with a png having a slight bit of transparency, which resulted in removing the transparency part, and leaving the white areas. To fix it, first I had to flatten, then trim.

Code: Select all

convert partial-trans.png -flatten -fuzz 1% -trim +repage trimmed.jpg
