[CALUG] adding simple text to images

[Ken Jackson]

If you have the ImageMagick package installed, you can use the 'convert' 
command:

    convert -gravity SouthWest -annotate +10+10 "Some Text" input.jpeg 
output.jpeg

There's also the GraphicsMagick package, which spun off of the other:

   gm convert -gravity SouthWest -draw 'text +10+10 "Some Text"' \
         -font <full path of .ttf file> input.jpeg output.jpeg

I had to specify the full path for gm to work.
Each tool has a million switches to alter the result.

The nice thing about the command-line approach is it's inherently 
scriptable.
Once you get a working script, you can convert a million files in one go.
