I would like to add some text at the bottom left and some other at the bottom right of image files using GraphicsMagick.
The text should be in black, with a 50% transparent white box.
I've seen some examples but can't get them to work. One of the errors is about fonts gm convert: Unable to read font (/usr/share/fonts/type1/gsfonts/n019003l.pfb) [No such file or directory]. although I'm using very common fonts like DejaVu Sans or Verdana.
The command I'm trying is: gm convert -font verdana -pointsize 30 -fill "white" -draw "text 10,50 'my text'" $image_in $image_out
Also tried -annotate, but it seems it's not accepted.
I've added the imagemagick tag, because it's the closest to graphicsmagick, and I could also use an imagemagick's command, although I'd prefer a graphicsmagick one.
