ImageMagick command arguments

Note to self for common commands use by ImageMagick:

  • The manual

  • The examples

  • Geometry specification

    • [width]x[height][+-x+-y]

    • Cropping

      • Always use "+repage" or else...

      • When cropping do specify +0+0 or you'll get lots of tiles

    • Checking the output on the command line -- use 
      xpm:-
      for output (
      -compress none pbm:-
      is also kind-of usable).

    • Thumbnail gallery: 
      montage input*.jpg -tile XxY -mode Concatenate output.jpg
