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 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 specification is ppmdestfile.ppm.
If it's multiple files, their file specifications are ppmdestfile_1.ppm,
ppmdestfile_2.ppm, etc.
When you specify the -writeands option, the filenames above are modified to include the
string xor as in ppmdestfile_xor.ppm or ppmdestfile_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 ppmdestfile_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.
