NAME
winicontoppm - convert a Windows .ico image into 1 or more PPM images
SYNOPSIS
winicontoppm [-writeands] [-allicons|-bestqual] [-multippm] [-verbose]
[iconfile] [ppmdestfile]
DESCRIPTION
This program is part of Netpbm(1).
winicontoppm reads a Microsoft Windows .ico file and converts it to one
or more PPMs.
A Windows icon contains one or more images, at different resolutions
and color depths. Each image has an ’and’ mask, which contains
transparancy data.
By default, the output goes to Standard Output. If you specify
ppmdestfile, output goes into one or more files named as follows. If
it’s just one file (i.e. you specify the -multippm option or don’t
specify -allicons), the file name is ppmdestfile.ppm. If it’s multiple
files, their file names are ppmdestfile_1.ppm, ppmdestfile_2.ppm, etc.
When you specify the -writeands option, the file names above are modi-
fied to include the string xor as in ppmdestfile_xor.ppm or ppmdest-
file_xor_1.ppm.
winicontoppm can convert .ico images with 1, 4, 8, 24, or 32 bits per
pixel. Before Netpbm 10.15 (April 2003), it could not handle 24 and
32.
OPTIONS
-writeands
For each icon written, also write the ’and’ (transparancy) mask
as a separate PBM file. It’s name is of the form ppmdest-
file_and.pbm or ppmdestfile_and_1.pbm.
-allicons
Extract all images from the .ico file.
-bestqual
Extract only the best quality (largest, then highest bpp) image
from the .ico file.
-multippm
Write all PPMs to a single file.
