ppmtomap(1) General Commands Manual ppmtomap(1)NAME
ppmtomap - extract all colors from a portable pixmap
DESCRIPTION
This program exists only for backward compatibility.
Use pnmcolormap, which replaced it in January 2002.
One trivial difference between ppmtomap and pnmcolormap all is that if the input is PBM or PGM, ppmtomap would produce PPM output, whereas
pnmcolormap all produces the same kind of output as the input. This should not be very noticeable, though, as PBM and PGM images are usu-
ally usable anywhere a PPM image is.

pnmquant(1) General Commands Manual pnmquant(1)NAME
pnmquant - quantize the colors in a Netpbm image to a smaller set
SYNOPSIS
pnmquant [-center|-meancolor|-meanpixel] [-floyd|-fs] [-nofloyd|-nofs] [-spreadbrightness|-spreadluminosity] ncolors [pnmfile]
All options can be abbreviated to their shortest unique prefix. You may use two hyphens instead of one to designate an option. You may
use either white space or equals signs between an option name and its value.
DESCRIPTION
Reads a PNM image as input. Chooses ncolors colors to best represent the image, maps the existing colors to the new ones, and writes a PNM
image as output.
This program is simply a combination of pnmcolormap and pnmremap, where the colors of the input are remapped using a color map which is
generated from the colors in that same input. The options have the same meaning as in those programs. See their documentation to under-
stand pnmquant.
It is much faster to call pnmcolormap and pnmremap directly than to run pnmquant. pnmquant is just a convenience.
ppmquant is an older program which does the same thing as pnmquant, but on only PPM images. It is, however, faster than either pnmquant or
ppmcolormap/pnmremap.

Hi All,
Having recently started a new job, a Data Center Migration in fact I have been tasked with looking at some of the older Solaris boxes when I came across this little gem.

For any SunOS 5.XX release, it appears prior to the "login:" prompt (as if a "uname" command is run).
Would anyone know where that initial display of SunOS release comes from upon a remote login and how I can stop if from displaying?
Thank you (4 Replies)
