NAME

       winicontoppm - convert a Windows .ico image into 1 or more PPM images

SYNOPSIS

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

DESCRIPTION

       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 transparency 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.

OPTIONS

       In addition to the options common to all programs based on libnetpbm (most notably -quiet,
       see
        Common  Options  ⟨index.html#commonoptions⟩  ),  winicontoppm  recognizes  the  following
       command line options:

       -writeands
              For each icon written, also write the 'and' (transparency) 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.
