Script Download: rounded_corner.sh (v2)
Ever wanted a script that would round the corners of images for you? Well, if you said yes, I wrote myself a bash script to do just that. As of this post it can do the following: round of corners of images and it can also add a glass-bubble effect as described in the ImageMagick tutorials. You can specify the border radius and a background color, which is handy if you are making JPEGs. The script’s help screen is shown below, as well as a couple of samples. Radius sizes are in pixels.
./rounded_corner.sh <inputfile> <outputfile> [options] -m Method [plain or glass-bubble] -r Corner Radius -b Background Color Method can be plain or glass-bubble at the moment. (default: plain) Radius specifies the radius of the rounded corners. (default: 15) Note: This should be able to function as filter command, so if you wanted rounded thumbnails of a particular size you can: convert <bigfile> -resize 200x200 png:- | ./rounded_corner.sh png:- smallrounded.png" 1>&2
