NAME

       SDL::Color - Format independent color description

   CATEGORY
       Core, Video, Structure

SYNOPSIS

	my $black = SDL::Color->new(0, 0, 0);
	my $color = SDL::Color->new(255, 0, 0);
	my $r = $color->r; # 255
	my $g = $color->g; # 0
	my $b = $color->b; # 0
	$color->g(255);
	$color->b(255);
	# $color is now white

DESCRIPTION

       "SDL_Color" describes a color in a format independent way.

METHODS

   new
	my $color = SDL::Color->new(255, 0, 0);

       The constructor creates a new color with the specified red, green and blue values.

   r
	my $r = $color->r;
	$color->r(128);

       If passed a value, this method sets the red component of the color; if not, it returns the red component of the color.

   g
	my $g = $color->g;
	$color->g(128);

       If passed a value, this method sets the green component of the color; if not, it returns the green component of the color.

   b
	my $b = $color->b;
	$color->b(128);

       If passed a value, this method sets the blue component of the color; if not, it returns the blue component of the color.

NAME

       SDL::Color - a SDL perl extension

SYNOPSIS

	 $color = new SDL::Color ( -r => 0xde, -g => 0xad, -b =>c0 );
	 $color = new SDL::Color -surface => $app, -pixel => $app->pixel($x,$y);
	 $color = new SDL::Color -color => SDL::NewColor(0xff,0xaa,0xdd);

DESCRIPTION

       "SDL::Color" is a wrapper for display format independent color representations, with the same interface as SDL::Color.

   new ( -color => )
       "SDL::Color::new" with a "-color" option will construct a new object referencing the passed SDL_Color*.

   new (-r => , -g => , -b => )
       "SDL::Color::new" with "-r,-g,-b" options will construct both a SDL_Color structure, and the associated object with the specified vales.

   new (-pixel =>, -surface =>)
       "SDL::Color::new" with "-pixel,-surface" options will generate a SDL_Color* with the r,g,b values associated with the integer value passed
       by "-pixel" for the given "-surface"'s format.

   r ( [ red ] ), g( [ green ] ), b( [ blue ] )
       "SDL::Color::r, SDL::Color::g, SDL::Color::b" are accessor methods for the red, green, and blue components respectively.  The color value
       can be set by passing a byte value (0-255) to each function.

   pixel ( surface )
       "SDL::Color::pixel" takes a "SDL::Surface" object and r,g,b values, and returns the integer representation of the closest color for the
       given surface.
