NAME

Convert::Color::CMYK - a color value represented as cyan/magenta/yellow/key

SYNOPSIS

Directly:


            

              
              
use Convert::Color::CMYK;
my $red = Convert::Color::CMYK->new( 0, 1, 1, 0 );
# Can also parse strings
my $pink = Convert::Color::CMYK->new( '0,0.3,0.3,0' );

Via Convert::Color:


            

              
              
use Convert::Color;
my $cyan = Convert::Color->new( 'cmyk:1,0,0,0' );

DESCRIPTION

Objects in this class represent a color in CMYK space, as a set of four floating-point values in the range 0 to 1.

CONSTRUCTOR

new


            

              
              
$color = Convert::Color::CMYK->new( $cyan, $magenta, $yellow, $key );

Returns a new object to represent the set of values given. These values should be floating-point numbers between 0 and 1. Values outside of this range will be clamped.


            

              
              
$color = Convert::Color::CMYK->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


            

              
              
cyan,magenta,yellow,key

containing the three floating-point values in decimal notation.

METHODS

cyan


            

              
              
$c = $color->cyan;

magenta


            

              
              
$m = $color->magenta;

yellow


            

              
              
$y = $color->yellow;

key


            

              
              
$k = $color->key;

Accessors for the four components of the color.

black


            

              
              
$k = $color->black;

An alias to key

cmyk


            

              
              
( $cyan, $magenta, $yellow, $key ) = $color->cmyk;

Returns the individual cyan, magenta, yellow and key components of the color value.
