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.
