       sunicontopnm - convert a Sun icon into a Netpbm image

       sunicontopnm [iconfile]

       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 convert the PGM output to the proper color Netpbm image.

       It seems that this icon format was used in Sunview and was usable in its  successor  Open-
       look/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

       pbmtosunicon(1) , winicontoppm(1) , xpmtoppm(1) , xbmtoppm(1) , infotopam(1) , pbm(1)


       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

       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.
