NAME
winicontoppm - convert a Windows .ico file into 1 or more portable
pixmap files
SYNOPSIS
winicontoppm [-writeands] [-allicons|-bestqual] [-multippm] [-verbose]
[iconfile] [ppmdestfile]
DESCRIPTION
Reads a Microsoft Windows .ico file, converts it to one or more ppms.
A Windows icon contains 1 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 pp-
mdestfile, 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 specification is ppmdestfile.ppm. If it's
multiple files, their file specifications are ppmdestfile_1.ppm, pp-
mdestfile_2.ppm, etc.
When you specify the -writeands option, the filenames above are modi-
fied to include the string xor as in ppmdestfile_xor.ppm or ppmdest-
file_xor_1.ppm.
winicontoppm can convert images with 1, 4, 8, 24 or 32 bits per pixel
(bpp).
OPTIONS
-writeands
For each icon written, also write the 'and' (transparancy) mask
as a seperate 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.
