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


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


       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 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
       pixel.   Before  Netpbm  10.15 (April 2003), it could not handle 24 and


              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.

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

              Write all PPMs to a single file.
