NAME
       img-sun - Img, Sun Raster Format (sun)

SYNOPSIS
       package require TTkk

       package require iimmgg::::ssuunn  ??11..33??

       iimmaaggee ccrreeaattee pphhoottoo ?name? ?options?


DESCRIPTION
       The  package  iimmgg::::ssuunn  is  a sub-package of IImmgg. It can be loaded as a
       part of the complete Img support, via ppaacckkaaggee rreeqquuiirree IImmgg,  or  on  its
       own, via ppaacckkaaggee rreeqquuiirree iimmgg::::ssuunn.

       Like  all packages of IImmgg it does not provide new commands, but extends
       the existing TTkk command iimmaaggee so  that  it  supports  files  containing
       raster  images  in  the  Sun  Raster  Format  (sun).  More specifically
       iimmgg::::ssuunn extends TTkk's pphhoottoo image type.

       The name of the new format handler is ssuunn.  This handler  provides  new
       additional  configuration  options.  See  section  SSUUNN OOPPTTIIOONNSS for more
       detailed explanations.

       All of the above means that in a call like

       iimmaaggee ccrreeaattee pphhoottoo ?name? ?options?

       [1]    Image data in sun format (options -ddaattaa and -ffiillee)  is  detected
              automatically.

       [2]    The  format  name  ssuunn  is recognized by the option -ffoorrmmaatt.  In
              addition the value for the option is treated  as  list  and  may
              contain  any  of  the  special  options  listed  in  section SSUUNN
              OOPPTTIIOONNSS.
