or more PPMs.
A Windows icon contains one or more images, at different resolutions

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-
winicontoppm can convert .ico images with 1, 4, 8, 24, or 32 bits per

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.
Extract all images from the .ico file.

from the .ico file.
Write all PPMs to a single file.
