NAME

       Imager::Color::Float - Rough floating point sample color handling

SYNOPSIS

	 $color = Imager::Color->new($red, $green, $blue);
	 $color = Imager::Color->new($red, $green, $blue, $alpha);
	 $color = Imager::Color->new("#C0C0FF"); # html color specification

	 $color->set($red, $green, $blue);
	 $color->set($red, $green, $blue, $alpha);
	 $color->set("#C0C0FF"); # html color specification

	 ($red, $green, $blue, $alpha) = $color->rgba();
	 @hsv = $color->hsv(); # not implemented but proposed

	 $color->info();

DESCRIPTION

       This module handles creating color objects used by Imager.  The idea is that in the future this module will be able to handle color space
       calculations as well.

       A floating point Imager color consists of up to four components, each in the range 0.0 to 1.0. Unfortunately the meaning of the components
       can change depending on the type of image you're dealing with:

       o   for 3 or 4 channel images the color components are red, green, blue, alpha.

       o   for 1 or 2 channel images the color components are gray, alpha, with the other two components ignored.

       An alpha value of zero is fully transparent, an alpha value of 1.0 is fully opaque.

METHODS

       new This creates a color object to pass to functions that need a color argument.

       set This changes an already defined color.  Note that this does not affect any places where the color has been used previously.

       rgba()
	   This returns the red, green, blue and alpha channels of the color the object contains.

       info
	   Calling info merely dumps the relevant color to the log.
