This is a bash script that performs, auto-magically, a seperation (many croppings, actually) of picture/icon collection images into individual, smaller images, specified by the user.
- This script is written in the Bash dialect, so a Bash shell is required, I guess.
- The script needs to have the imagemagick toolkit installed. It makes use of:
- convert (-crop) to crop out the individual files
- identify (-format) to find out the dimensions of the base image
Use the script as follows:
./cutout_icons.sh, followed by eight(8) parameters, in the following order:
- input filename
- output filename root
- output filename ending (must be a graphics format, e.g.
.jpg) - square side length of output icon files in pixels (currently, only square-sized output files are possible)
- x separation between icons, in pixels (0 if nonexistent)
- y separation between icons, in pixels (0 if nonexistent)
- x offset, starting on the left, in pixels (0 if nonexistent)
- y offset, starting on the top, in pixels (0 if nonexistent)
Alternatively, since this can get kinda messy, you can, of course, use standard linux stdin/out/err behaviour and put these parameters in a file, in the right order and separated by whitespace (e.g. Newlines).
Then, you can call the script with:
cutout_icons.sh $(< parameter_file.txt). An example parameter file is provided.

- general script cleanup
- making the script more efficient
- also, more user-friendly-ness
