What you will get from the iPaq here is a binary image, turned by 90
degrees in a 16bpp format RGB:565 (i.e. 5 bits red, 6 bits green, 5 bits
blue), in raw format. You should be able to convert this using
image-magick or similar by specifying this along with 320x240 as
resolution (not 240x320 because it is turned by 90 degrees).
