NAME
       sunicontopnm - convert a Sun icon into a Netpbm image

SYNOPSIS
       sunicontopnm [iconfile]

DESCRIPTION
       This program is part of Netpbm(1)

       sunicontopnm  reads a Sun icon as input and produces a PBM or PGM image
       as output.

       If the input is of the Depth=8 variety, the output is PGM.   Otherwise,
       it  is PBM.  Before Netpbm 10.53 (December 2010), the program would not
       work on a Depth=8 icon.

       If the input is color, the output is still PGM (the  program  can't  do
       any  better  because  developers haven't figured out how).  If you know
       the palette used by the Sun icon image, you can use pamlookup  to  con‐
       vert the PGM output to the proper color Netpbm image.

ABOUT SUN ICONS
       It  seems  that	this icon format was used in Sunview and was usable in
       its successor Openlook/Openwindows in Sun 4.1.1, which offered backward
       compatibility  for Sunview, including the icons.	 Sunview's desktop was
       monochrome.  OpenWindows had color icons.  Sun 4 came with OpenWindows.
       OpenWindows appears to have been an X-based gui so presumably the icons
       were mostly XPM files.

       So in addition to sunicontopnm, you should try xpmtoppm and xbmtopbm on
       icons from a Sun Workstation.

HISTORY
       Jef Poskanzer wrote the program under the name icontopbm in 1988.

       In October 2010, Prophet Of The Way (afu@wta.att.ne.jp) converted it to
       use the more recent 'packed PBM' library functions, thus speeding it up

       Netpbm 10.53 (December 2010) renamed the program to sunicontopnm.  This
       name reflects the fact that there are lots of kinds  of	icons  in  the
       world  besides  the  Sun	 variety, Windows ones being most popular.  It
       also takes into account the new Depth=8 capability (see below).

       Netpbm 10.53 (December 2010) added the ability  to  work	 with  Depth=8
       icon input and input with 32 bit 'items.'  Whereas the previous program
       always produced PBM output, the new program produced PGM in the Depth=8
       case.
