The application was to insert text into an already existing JPG image.
The image did come from an USB webcam Logitech E3500.
To do that under Ubuntu 0810 was no problem, everything was already installed.
Under SlugOS it was some more work.
(:table border=0 width=100% bgcolor=#ffffff:) Install ImageMagick (:cell:)
$ ipkg-opt update $ ipkg-opt install imagemagick $ ipkg-opt install ghostscript $ ipkg-opt install ttf-bitstream-vera $ ipkg install libcairo2

I found no way to tell linux where the fonts are located.
Hence you have to tell the font path to the program convert.
For convenience I copied the font Vera.ttf from
/opt/share/fonts/bitstream-vera/Vera.ttf to the application folder.
(:table border=0 width=100% bgcolor=#ffffff:) Example (:cell:)
convert -font Vera.ttf -pointsize 20 -fill red -draw "text 20, 230 '`date`'" source.jpg target.jpg
(:tableend:)
The file source.jpg was 320x240 pixel. The size of the font was given with 20pt.
The goal was to give the image a time stamp.

Please see the attached image how it looks like.
