displaying rgb on an IRIS

[Vince Pugliese]

i was hoping some kind sgi user out there could
help me with the following:
 
i have a file containing rgb values for pixels
on a screen and i wish to display them on an IRIS.
essentially what i have done is translated an
image into a more "portable" format that consists
of
  # of pixels red_value green_value blue_value
  # of pixels red_value green_value blue_value
 and so on. since i don't regularly use IRIS' i'm not
familiar with how to do this sort of thing so I was
hoping that someone had a "short(?)" program that
would take this data and display it.
                             thanks in advance
