pamtosrf - convert a sequence of Netpbm images to a SRF image file
pamtosrf [-verbose] [netpbmfile]
This program is part of Netpbm(1)
pamtosrf reads a Netpbm image stream as input and produces a an SRF image file as output.
I don't know exactly what SRF is, but on popular use of it is in Garmin vehicle informa-
tion files, which tell a GPS receiver 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 dimensions 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 image: 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 pnmcat -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. Output is always on
Issue informational messages about the input and the conversion process.
srftopam was new in Netpbm 10.55 (June 2011).
It was contributed by Mike Frysinger.
