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.This color space may be considered as a cylinder, of height and radius 1. Hue represents the position of the color as the angle around the axis, the saturation the distance from the axis, and the value the height above the base. In this shape, the entire base of the cylinder is pure black, the axis through the centre represents the range of greys, and the circumference of the top of the cylinder contains the pure-saturated color wheel, with a pure white point at its centre.
Because the entire bottom surface of this cylinder contains black, a closely-related color space can be created by reshaping the cylinder into a cone by contracting the base of the cylinder into a point. The radius from the axis is called the chroma (though this is a different definition of ``chroma'' than that used by CIE).
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.
