PABX background
From Just Solve the File Format Problem
PABX background is a raster image format.
We have not located any information about its origin, but because XnView supports writing it, we can deduce some things about it.
Format details
It is apparently a text-based format, and always uses a color palette. It is somewhat like binary PNM, modified to use only ASCII characters.
Here is an example file:
