ImageMagick Magic!

Thursday, 12 June 2008

I enjoy using ImageMagick… most of it has been via PHP CLI, however here we have a short example in Bash:

#!/usr/bin/env bash
for file in `ls -d *.png`; do
  convert -crop 1280X985+0+24 $file 
  $(basename $file .png).jpg;
done

Basically this does the following:

• Makes a listing of all .png files in the current directory
• Runs the “convert” command (part of ImageMagick) on each .png file in that listing
• Crops the image specified by the geometry arguments
• Saves the result as a .jpg
