## 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)](https://www.chedong.com/phpMan.php/man/Netpbm/1/markdown).

       **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 be‐
       comes 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 concatena‐
       tion 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 Stan‐
       dard Output.



## OPTIONS
       In addition to the options common to all programs based on libnetpbm  (most  notably  **-quiet**,
       see ]8;;index.html#commonoptions\ Common Options]8;;\ ), **pamtosrf **recognizes the following command line option:



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