winicontopam: convert a Microsoft Windows icon file into a Netpbm PAM file

NAME

winicontopam - convert a Microsoft Windows icon file into a Netpbm PAM file

SYNOPSIS

winicontopam [-image=index | -allimages] [-andmasks] [-verbose] [icon_file]

All options can be abbreviated to their shortest unique prefix. You may use two hyphens instead of one to designate an option. You may use either white space or equals signs between an option name and its value.

DESCRIPTION

This program is part of Netpbm(1)

winicontopam reads a Microsoft Windows icon file and converts it to one or more RGB_ALPHA Netpbm PAM files.

The alpha channel is copied from the 8-bit transparency data from the icon, if present. If no 8-bit transparency data is available, the alpha channel is constructed from the so-called ‘AND mask’.

The output goes to Standard Output.

The output is a multi-image PAM file. If you want a separate file for each image, use pamsplit(1)

OPTIONS

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

-allimages

Convert all images in the input.

You may not specify this together with -image.

By default, winicontopam converts only the one ‘best quality’ image (largest, then most bits per pixel).

-image=index

Convert image number index (starting with zero).

You may not specify this together with -allimages.

By default, winicontopam converts the ‘best quality’ image (largest, then most bits per pixel).

-andmasks

If the image to be extracted contains both 8-bit transparency data and AND mask, write a five-channel Netpbm PAM file with the AND mask stored to the fifth plane.

-verbose

HISTORY

winicontopam was new in Netpbm 10.63 (June 2013). It obsoleted winicontoppm by providing more function and conforming better to Netpbm conventions.
