NAME
pamtosrf - convert a sequence of Netpbm images to a SRF image file
SYNOPSIS
pamtosrf [-verbose] [netpbmfile]
DESCRIPTION
This program is part of Netpbm(1).
pamtosrf reads a Netpbm image stream as input and produces a an SRF im-
age file as output. I don't know exactly what SRF is, but on popular
use of it is in Garmin vehicle information files, which tell a GPS re-
ceiver how to depict a vehicle on its display.
An SRF file can contain multiple images; each image in a multi-image
Netpbm input stream becomes one image in the SRF.
pamtosrf does not care how many images there are or what their dimen-
sions or content are. However, a Garmin vehicle information file has
specific requirements, so if you don't make your Netpbm input conform,
neither will your SRF output. For such a file, you should have two im-
age: the first for 3D oblique views of the vehicle and the second for
overhead views. Each image is a horizontal concatenation of 36 square
images, each rotated 10 degrees from the previous, thereby covering the
full 360 degree circle. You could create this concatenation with pnm-
cat -lr and you could create the invidual views with pnmrotate.
One way to use pamtosrf is to get an SRF file, convert it to PAM with
srftopam, manipulate it, then convert it back with pamtosrf.
netpbmfile is the input stream, which defaults to Standard Input. Out-
put is always on Standard Output.
OPTIONS
In addition to the options common to all programs based on libnetpbm
(most notably -quiet, see

following command line option:
