Sommaire

NAME

Graphics::Color - Device and library agnostic color spaces.

SYNOPSIS

Graphics color is a device and library agnostic system for creating and manipulating colors in various color spaces. 
   my $color = Graphics::Color::RGB->new(
       red => .5, green => .5, blue => .5, alpha => .5
   );
   say $color->as_string;

DISCLAIMER

I'm not an art student or a wizard of arcane color knowledge. I'm a normal programmer with a penchant for things graphical. Hence this module is likely incomplete in some places. Patches are encouraged. I've intentions of adding more color spaces as well as conversion routines (where applicable).

COLOR TYPES

The following color types are supported.

CMYK

HSL

RGB

YIQ

YUV

CONSTRUCTOR

Graphics::Color->new(%options);

Makes a new, useless Graphics::Color object. There's no reason to do this.

METHODS

derive

Clone this color but allow one of more of it's attributes to change by passing in a hashref of options: 
   my $new = $color->derive({ attr => $newvalue });

The returned color will be identical to the cloned one, save the attributes specified.

equal_to

Compares this color to the provided one. Returns 1 if true, else 0;

not_equal_to

The opposite of equal_to.
