winicontoppm - convert a Windows .ico image into 1 or more PPM images
winicontoppm [-writeands] [-allicons|-bestqual] [-multippm] [-verbose] [iconfile]
This program is part of Netpbm(1)
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.
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.
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.
