Ok so now im lost. I in now way consider myself above average in unix so here is how Im confused.

xwd | xwdtopnm | pnmtopng > screen.png

OK, I undertsand what xwd does, but what about xwdtopnm and pmtopng?

The version of solaris that my machine is running apparently doesnt support pnmtopng, soooo where do I go from here?
