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 image 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 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 pamcat  -lr  and  you  could  create  the  individual  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
       Standard Output.

OPTIONS

       In addition to the options common to all programs based on libnetpbm (most notably -quiet,
       see
        Common Options ⟨index.html#commonoptions⟩ ), pamtosrf recognizes  the  following  command
       line option:

       -verbose
              Issue informational messages about the input and the conversion process.
