NAME
       img-ppm - Img, Portable Pixmap format (ppm)

SYNOPSIS
       package require TTkk

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

       iimmaaggee ccrreeaattee pphhoottoo ?name? ?options?


DESCRIPTION
       The  package  iimmgg::::ppppmm  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::::ppppmm.

       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 Portable Pixmap format (ppm). More specifically
       iimmgg::::ppppmm extends TTkk's pphhoottoo image type.

       The name of the new format handler is ppppmm.  This handler does not  pro-
       vide additional configuration options.

       All of the above means that in a call like

       iimmaaggee ccrreeaattee pphhoottoo ?name? ?options?

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

       [2]    The format name ppppmm is recognized by the option -ffoorrmmaatt.
