convert::color::rgb16
Convert::Color::RGB16(3pm) User Contributed Perl Documentation Convert::Color::RGB16(3pm)
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.
$mix = $color->alpha_blend( $other, [ $alpha ] )
Return a new color which is a blended combination of the two passed into it. The optional $alpha parameter defines the mix ratio between
the two colors, defaulting to 0.5 if not defined. Values closer to 0 will blend more of $color, closer to 1 will blend more of $other.
$mix = $color->alpha16_blend( $other, [ $alpha ] )
Similar to "alpha_blend" but works with integer arithmetic. $alpha should be an integer in the range 0 to 65535.
$measure = $color->dst_rgb16( $other )
Return a measure of the distance between the two colors. This is the unweighted Euclidean distance of the three color components. Two
identical colors will have a measure of 0, pure black and pure white have a distance of 1, and all others will lie somewhere inbetween.
$measure = $color->dst_rgb16_cheap( $other )
Return a measure of the distance between the two colors. This is the sum of the squares of the differences of each of the color components.
This is part of the value used to calculate "dst_rgb16", but since it involves no square root it will be cheaper to calculate, for use in
cases where only the relative values matter, such as when picking the "best match" out of a set of colors. It ranges between 0 for
identical colours and 3*(65535^2) for the distance between pure black and pure white.
