SYNOPSIS

sunicontopnm [iconfile]

DESCRIPTION

sunicontopnm reads a Sun icon-format image (the monochrome icon format used historically on SunOS workstations) and writes a corresponding PBM (or PNM) image to standard output. If no input file is given, the icon is read from standard input.The output is always monochrome since Sun icons store only black-and-white pixels. This program is part of the Netpbm toolkit, which provides building blocks for image-format conversion pipelines.

INSTALL

sudo apt install netpbm
sudo dnf install netpbm
sudo pacman -S netpbm
sudo apk add netpbm
sudo zypper install netpbm
brew install netpbm
nix profile install nixpkgs#netpbm

CAVEATS

Sun icon files are an obsolete format. The tool is mainly useful for archival conversions. The complementary tool, pbmtosunicon, performs the reverse conversion from PBM to Sun icon format.

HISTORY

Part of the Netpbm package. The Sun icon format dates from the SunView/NeWS era of SunOS in the 1980s; the converter has been part of pbmplus / Netpbm since the early 1990s.
