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.
OPTIONS
There are no command line options defined specifically for sunicon-
topnm, but it recognizes the options common to all programs based on
libnetpbm (See
Common Options ⟨index.html#commonoptions⟩ .)
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.
