SYNOPSIS

            

              
              
use Graphics::Raylib::Color;
my $color   = Graphics::Raylib::Color::BLACK;
# alternatively:
use Graphics::Raylib::Color qw(:all);
my $color2  = MAROON;
my $gray    = Graphics::Raylib::Color::rgb(127,127,127);
my $rainbow = Graphics::Raylib::Color::rainbow(colors => 100);
push @colors, $rainbow->cycle for (1..100);
            
          

DESCRIPTION

Colors you can pass to raylib.

IMPLEMENTATION

As a color is basically a 32-bit integer (RGBA) in raylib, the constructors rgba and rgb do little more packing it into an integer and blessing it. Interpolating a color into a string results in a tuple of the form "(r: %u, g: %u, b: %u, a: %u)".

METHODS AND ARGUMENTS

rgba($red, $green, $blue, $alpha)

Constructs a new Graphics::Raylib::Color out of 8-bit (0-255) components.

rgb($red, $green, $blue)

Constructs a new Graphics::Raylib::Color instance out of an opaque color. Calls rgba with $alpha = 255.

($r, $g, $b, $a) = colors

Returns a list with the red, green, blue and alpha components of the color.

rgb($red, $green, $blue)

Constructs a new Graphics::Raylib::Color instance out of an opaque color. Calls rgba with $alpha = 255.

color($color_32bit)

Constructs a Color out of a 32 bit integer.

new($string, [$alpha = 255])

Returns a new Color that represent the color specified by the string. This string should be prefixed by the name of the color space to which it applies. For example

            

              
              
rgb:RED,GREEN,BLUE
rgb8:RRGGBB
rgb16:RRRRGGGGBBBB
hsv:HUE,SAT,VAL
hsl:HUE,SAT,LUM
cmy:CYAN,MAGENTA,YELLOW
cmyk:CYAN,MAGENTA,YELLOW,KEY
vga:NAME
vga:INDEX
x11:NAME
            
          

This leverages Convert::Color under the hood. Refer to its documentation for more information.

hsv($hue, $sat, $val, [$alpha = 255])

Returns a new Color out of HSV components.

rainbow(colors => $color_count)

Returns a code reference that cycles through the rainbow colors on each evaluation. $color_count is the total number of colors before bouncing back. Default is 7.
