NAME

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

CONTENTS

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

CW$color = Convert::Color::CMYK->new( CW$cyan, CW$magenta, CW$yellow, CW$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.

CW$color = Convert::Color::CMYK->new( CW$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

CW$c = CW$color->cyan

CW$m = CW$color->magenta

CW$y = CW$color->yellow

CW$k = CW$color->key

Accessors for the four components of the color.

CW$k = CW$color->black

An alias to key

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

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