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  de‐
       velopers  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.



OPTIONS
       There are no command line options defined specifically for sunicontopnm,  but  it  recognizes
       the options common to all programs based on libnetpbm (See  Common Options .)


ABOUT SUN ICONS
       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
       Workstation.

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

       In October 2010, Prophet Of The Way (afu AT wta.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.
