Convert::Color::HSL(3pm) User Contributed Perl Documentation Convert::Color::HSL(3pm) NAME
"Convert::Color::HSL" - a color value represented as hue/saturation/lightness SYNOPSIS
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 form hue,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
