Instantiate

new

Instantiate an Colouring::In::XS Object using a supported colour formated string or RGBA array reference.

my $colour = Colouring::In::XS->new('hsla(0, 0%, 100%, 0.3)');
my $colour = Colouring::In::XS->new([255, 255, 255, 0.3]);

rgb

Instantiate an Colouring::In::XS Object opaque colour from decimal red, green and blue (RGB) values.

my $colour = Colouring::In::XS->rgb(0, 0, 0);

rgba

Instantiate an Colouring::In::XS Object transparent colour from decimal red, green, blue and alpha (RGBA) values.

my $colour = Colouring::In::XS->rgb(0, 0, 0, 0.5);

hsl

Instantiate an Colouring::In::XS Object opaque colour from hue, saturation and lightness (HSL) values.

my $colour = Colouring::In::XS->hsl(0, 0%, 100%);

hsla

Instantiate an Colouring::In::XS Object tranparent colour from hue, saturation, lightness and alpha (HSLA) values.

my $colour = Colouring::In::XS->hsla(0, 0%, 100%, 1);

Methods

my $string = $colour->toCSS;

This method is called on stringification of a Colouring::In::XS Object.

toRGB

Returns an opaque colour string from decimal red, green and blue (RGB) values.

my $string = $colour->toCSS;
