NAME
"Convert::Color::HSL" - a color value represented as hue/saturation/lightnessSYNOPSIS
Directly:use Convert::Color::HSL; my $red = Convert::Color::HSL->new( 0, 1, 0.5 ); # Can also parse strings my $pink = Convert::Color::HSL->new( '0,1,0.8' );
Via Convert::Color:
use Convert::Color; my $cyan = Convert::Color->new( 'hsl:300,1,0.5' );
DESCRIPTION
Objects in this class represent a color in HSL 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 lightness are in the range 0 to 1.CONSTRUCTOR
$color = Convert::Color::HSL->new( $hue, $saturation, $lightness )
Returns a new object to represent the set of values given. The hue should be in the range 0 to 360 (exclusive), and saturation and lightness should be between 0 and 1. Values outside of these ranges will be clamped.$color = Convert::Color::HSL->new( $string )
Parses $string for values, and construct a new object similar to the above three-argument form. The string should be in the formhue,saturation,lightnes
containing the three floating-point values in decimal notation.
METHODS
$h = $color->hue
$s = $color->saturation
$v = $color->lightness
Accessors for the three components of the color.( $hue, $saturation, $lightness ) = $color->hsl
Returns the individual hue, saturation and lightness components of the color value.SEE ALSO
