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).
