NAME

       Graphics::Color::CMYK - CMYK color model

VERSION

       version 0.29

SYNOPSIS

	   use Graphics::Color::CMYK;

	   my $color = Graphics::Color::CMYK->new({
	       cyan    => 120,
	       magenta => .5,
	       yellow  => .25,
	       key     => .5
	   });

DESCRIPTION

       Graphics::Color::CMYK represents a Color in CMYK color model.  Cyan stands for Cyan Magenta Yellow Key (or black).

ATTRIBUTES

   cyan
   c
       Set/Get the cyan component of this Color.

   magenta
   m
       Set/Get the magenta component of this Color.

   yellow
   y
       Set/Get the yellow component of this Color.

   key
   k
       Set/Get the key (black) component of this Color.

   name
       Get the name of this color.  Only valid if the color was created by name.

METHODS

   as_string
       Get a string version of this Color in the form of:

       CYAN,MAGENTA,YELLOW,KEY

   as_percent_string
       Return a percent formatted value for this color.

   as_array
       Get the CMYK values as an array

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

   not_equal_to
       The opposite of "equal_to".

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

   $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

   $c = $color->cyan
   $m = $color->magenta
   $y = $color->yellow
   $k = $color->key
       Accessors for the four components of the color.

   $k = $color->black
       An alias to "key"

   ( $cyan, $magenta, $yellow, $key ) = $color->cmyk
       Returns the individual cyan, magenta, yellow and key components of the color value.
