This program is part of Netpbm.
pdbimgtopam reads a Palm Pilot Image Viewer image (and Image record in a PDB file) as input, from Standard Input or palmfile, and produces a PAM image as output.
If the Pilot image is monochrome, the PAM output has maxval 1. Otherwise, it has maxval 255. Note that Pilot images are always monochrome. The PAM image has tuple type GRAYSCALE.
If you don't specify this, pdbimgtopam ignores any image note.
pdbimgtopam was new in Netpbm 10.52 (September 2010). It was modelled after Eric A. Howe's imgvtopbm package, which dates back to September 1997.
