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
       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 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.
