NAME

       SDL::PixelFormat - Stores surface format information

   CATEGORY
       Core, Video, Structure

SYNOPSIS

	       my $surface = SDL::Surface->new( ...
	       $surface->format; #this returns the PixelFormat object attached to this surface

       PixelFormat is only created in a "SDL::Surface". This module only provides getters to the surface's pixelformat. Later on we will provide
       setting capability.

DESCRIPTION

       An "SDL::PixelFormat " stores surface format information

METHODS

   palette
	       $surface->format->palette;

       Returns the "SDL_Palette" and SDL::Palette of the format of the surface.

   BitsPerPixel
	       $surface->format->BitsPerPixel;

       The number of bits used to represent each pixel in a surface. Usually 8, 16, 24 or 32. (1 to 7 are not allowed when creating a surface or
       open a video mode

   BytesPerPixel
	       $surface->format->BytesPerPixel;

       The number of bytes used to represent each pixel in a surface. Usually one to four.

   [RGBA]loss
	       $surface->format->Rloss; #red   loss
	       $surface->format->Bloss; #blue  loss
	       $surface->format->Gloss; #green loss
	       $surface->format->Aloss; #alpha loss

       Precision loss of each color component (2[RGBA]loss)

   [RGBA]shift
	       $surface->format->Rshift; #red	shift
	       $surface->format->Bshift; #blue	shift
	       $surface->format->Gshift; #green shift
	       $surface->format->Ashift; #alpha shift

       Binary left shift of each color component in the pixel value

   [RGBA]mask
	       $surface->format->Rmask; #red   mask
	       $surface->format->Bmask; #blue  mask
	       $surface->format->Gmask; #green mask
	       $surface->format->Amask; #alpha mask

       Binary left shift of each color component in the pixel value

   colorkey
	       $surface->format->colorkey;

       Pixel value of transparent pixels.

   alpha
	       $surface->format->alpha;

       Overall surface alpha value
