I recently needed to make a set of several favicons, so I went to the web to see if anyone had a script I could
Sure enough, I found one written by Joshua McGee: “Create a favicon with ImageMagick” (not reproduced here for copyright reasons).
It was a simple enough script, just a series of escaped commands. I noticed, however, that it assumed a few things:
- An image file was specified on the command line,
- The image existed, and
- Imagemagik was installed.
In other words, the script was not developed defensively. This makes sense: it was just a bang-out.
The script had no inline documentation†, and if a favicon file that already existed in the current directory would be silently overwritten—not good.
I’m clumsy: I delete and overwrite files all the time, so I could use a little help. Maybe I can tidy up the script? (more…)
