Palm bitmap

Palm bitmap (variously called Palm Pilot Tbmp, Palm Pilot Bitmap, Palm pixmap, etc.) is a raster image file format. It supports a variety of image types and compression schemes.

Format
A Palm bitmap file may contain multiple versions (called renditions) of the same image, with different color types.

The file (and each rendition) begins with a header. The first 10 bytes of the header are common to all versions. After that, old versions of the format have 6 more header bytes, for a total of 16. Version 3 has 14 more bytes, for a total of 24.

Software

 * Netpbm: pnmtopalm, palmtopnm
 * ImageMagick (format named "PALM")
