The CairoContent class

INTRODUCTION

       CairoContent  is  used  to describe the content that a surface will contain, whether color information, alpha information (translucence vs.
       opacity), or both.

	Note: The large values here are designed to keep CairoContent values distinct from CairoContent values	so  that  the  implementation  can
       detect the error if users confuse the two types.

CLASS SYNOPSIS

       CairoContent

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
