converts MicroDesign Area format to PBM
TLDR
Convert a MicroDesign area to PBM on stdout
$ mdatopbm [input.mda] > [output.pbm]
Read from stdin and write PBM on stdout$ cat [input.mda] | mdatopbm > [output.pbm]
Double-height output (for non-square PCW pixels)$ mdatopbm -d [input.mda] > [output.pbm]
Invert black/white in the output$ mdatopbm -i [input.mda] > [output.pbm]
SYNOPSIS
mdatopbm [-d] [-i] [mdafile]
DESCRIPTION
mdatopbm converts MicroDesign Area files to PBM. MicroDesign was a desktop publishing program for the Amstrad PCW range of computers, and its .mda files store bitmap clip art at the PCW's non-square pixel ratio. The -d option doubles the vertical resolution so the image appears at correct proportions on a square-pixel display.Output is written to standard output. The tool is part of the Netpbm toolkit.
PARAMETERS
-d, -double
Double the height of the image to compensate for the rectangular pixel aspect ratio of the Amstrad PCW screen.-i, -invert
Swap foreground and background, producing white-on-black output.mdafile
Input MicroDesign Area (.mda) file. Reads from standard input if omitted.
INSTALL
sudo apt install netpbm
sudo dnf install netpbm

sudo apk add netpbm
sudo zypper install netpbm
brew install netpbm
nix profile install nixpkgs#netpbm
CAVEATS
Only the MicroDesign Area (.mda) variant is supported; documents from MicroDesign Plus may need to be exported to .mda first. The format is monochrome (1 bpp).
