NAME

Convert::Color::RGB16 - a color value represented as red/green/blue in 16-bit integers

SYNOPSIS

Directly:

use Convert::Color::RGB16;

my $red = Convert::Color::RGB16->new( 65535, 0, 0 );

# Can also parse strings
my $pink = Convert::Color::RGB16->new( '65535,49152,49152' );

# or
$pink = Convert::Color::RGB16->new( 'ffffc000c000' );

Via Convert::Color:

use Convert::Color;

my $cyan = Convert::Color->new( 'rgb16:0,65535,65535' );

DESCRIPTION

Objects in this class represent a color in RGB space, as a set of three integer values in the range 0 to 65535; i.e. as 16 bits.

For representations using floating point values, see Convert::Color::RGB. For representations using 8-bit integers, see Convert::Color::RGB8.

CONSTRUCTOR

$color = Convert::Color::RGB16->new( $red, $green, $blue )

Returns a new object to represent the set of values given. These values should be integers between 0 and 65535. Values outside of this range will be clamped.

$color = Convert::Color::RGB16->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

red,green,blue

containing the three integer values in decimal notation. It can also be given in the form of a hex encoded string, such as would be returned by the rgb16_hex method:

rrrrggggbbbb

METHODS

$r = $color->red

$g = $color->green

$b = $color->blue

Accessors for the three components of the color.

( $red, $green, $blue ) = $color->rgb16

Returns the individual red, green and blue color components of the color value in RGB16 space.

$str = $color->hex

Returns a string representation of the color components in the RGB16 space, in a convenient RRRRGGGGBBBB hex string.
