NAME

       egd - egd - erlang graphical drawer.

DESCRIPTION

       egd - erlang graphical drawer

DATA TYPES

	 color() :

	 egd_image() :

	 font() :

	 point() = {integer(), integer()} :

	 render_option() = {render_engine, opaque} | {render_engine, alpha} :

EXPORTS

       color(Color::Value | Name) -> color()

	      Types  Value = {byte(), byte(), byte()} | {byte(), byte(), byte(), byte()}
		     Name  = black | silver | gray | white | maroon | red | purple | fuchia | green | lime | olive | yellow | navy | blue | teal |
		     aqua

	      Creates a color reference.

       create(Width::integer(), Height::integer()) -> egd_image()

	      Creates an image area and returns its reference.

       destroy(Image::egd_image()) -> ok

	      Destroys the image.

       filledEllipse(Image::egd_image(), P1::point(), P2::point(), Color::color()) -> ok

	      Creates a filled ellipse object.

       filledRectangle(Image::egd_image(), P1::point(), P2::point(), Color::color()) -> ok

	      Creates a filled rectangle object.

       line(Image::egd_image(), P1::point(), P2::point(), Color::color()) -> ok

	      Creates a line object from P1 to P2 in the image.

       rectangle(Image::egd_image(), P1::point(), P2::point(), Color::color()) -> ok

	      Creates a rectangle object.

       render(Image::egd_image()) -> binary()

	      Equivalent to render(Image, png, [{render_engine, opaque}]) .

       render(Image::egd_image(), Type::png | raw_bitmap) -> binary()

	      Equivalent to render(Image, Type, [{render_engine, opaque}]) .

       render(Image::egd_image(), Type::png | raw_bitmap, Options::[render_option()]) -> binary()

	      Renders a binary from the primitives specified by egd_image(). The binary can either be a raw bitmap with rgb tripplets or a  binary
	      in png format.

       save(Binary::binary(), Filename::string()) -> ok

	      Saves the binary to file.

       text(Image::egd_image(), P::point(), Font::font(), Text::string(), Color::color()) -> ok

	      Creates a text object.

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.
