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.
