NAME

       "Convert::Color::HSV" - a color value represented as hue/saturation/value

SYNOPSIS

       Directly:

	use Convert::Color::HSV;

	my $red = Convert::Color::HSV->new( 0, 1, 1 );

	# Can also parse strings
	my $pink = Convert::Color::HSV->new( '0,0.7,1' );

       Via Convert::Color:

	use Convert::Color;

	my $cyan = Convert::Color->new( 'hsv:300,1,1' );

DESCRIPTION

       Objects in this class represent a color in HSV space, as a set of three floating-point values. Hue is stored as a value in degrees, in the
       range 0 to 360 (exclusive). Saturation and value are in the range 0 to 1.

CONSTRUCTOR

   $color = Convert::Color::HSV->new( $hue, $saturation, $value )
       Returns a new object to represent the set of values given. The hue should be in the range 0 to 360 (exclusive), and saturation and value
       should be between 0 and 1. Values outside of these ranges will be clamped.

   $color = Convert::Color::HSV->new( $string )
       Parses $string for values, and construct a new object similar to the above three-argument form. The string should be in the form

	hue,saturation,value

       containing the three floating-point values in decimal notation.

METHODS

   $h = $color->hue
   $s = $color->saturation
   $v = $color->value
       Accessors for the three components of the color.

   ( $hue, $saturation, $value ) = $color->hsv
       Returns the individual hue, saturation and value components of the color value.
