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 ⟨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.
