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

This program is part of Netpbm(1).

This program is essentially obsolete; The newer winicontopam is better.

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 modified to include the string xor as in ppmdestfile_xor.ppm or ppmdestfile_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.

In addition to the options common to all programs based on libnetpbm (most notably -quiet, see Common Options ), winicontoppm recognizes the following command line options:

-writeands

For each icon written, also write the 'and' (transparancy) mask as a separate 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.

If you specify neither this nor -bestqual, winicontoppm extracts the first image.

-bestqual

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

If you specify neither this nor -allicons, winicontoppm extracts the first image.

-multippm

Write all PPMs to a single file.
