pbmtomda - convert a portable bitmap to a Microdesign .mda

pbmtomda [-d][-i][--] [ pbmfile ]

Reads a portable bitmap file as input. Reads from stdin if input file is omitted. Produces a MicroDesign 2 area file (.MDA) as output.

Halve the height of the output file, to compensate for the aspect ratio used in MicroDesign files.
Invert the colours used.
--
End of options (use this if the filename starts with "-")

There's no way to produce files in MicroDesign 3 format. MD3 itself and mdatopbm(1) can read files in either format.

mdatopbm(1), pbm(5)
