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

$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. SEE ALSO
