winicontoppm – convert a Windows .ico file into 1 or more portable
pixmap files


winicontoppm [-writeands] [-allicons|-bestqual] [-multippm] [-verbose] [iconfile] [ppmdestfile]


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 modi‐
fied to include the string xor as in ppmdestfile_xor.ppm or ppmdest‐

winicontoppm can convert images with 1, 4, 8, 24 or 32 bits per pixel


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.

Extract all images from the .ico file.

Extract only the best quality (largest, then highest bpp) image
from the .ico file.

Write all ppms to a single file.
