SYNOPSIS

       surfaces  [-display host:display.screen] [-visual visual] [-window] [-root] [-speed number] [-rand] [-spin] [-wander] [-fps] [-surface sur-
       face-name] [-random-surface] [-dini] [-enneper] [-kuen] [-moebius] [-seashell] [-swallowtail]  [-bohemian]  [-whitney]  [-pluecker]  [-hen-

DESCRIPTION

       This draws one of several three dimensional parametric surfaces.

	       Display the Kuen surface.

       -surface moebius (Shortcut: -moebius)
	       Display the Moebius strip.

       -surface seashell (Shortcut: -seashell)
	       Display the seashell surface.

       -surface swallowtail (Shortcut: -swallowtail)
	       Display the swallowtail catastrophe.

       -surface bohemian (Shortcut: -bohemian)
	       Display the Bohemian dome.

       -surface whitney (Shortcut: -whitney)
	       Display the Whitney umbrella.

       -surface pluecker (Shortcut: -pluecker)
	       Display Pluecker's conoid.

       -surface henneberg (Shortcut: -henneberg)
	       Display Henneberg's minimal surface.

       -surface catalan (Shortcut: -catalan)
	       Display Catalan's minimal surface.

       -surface corkscrew (Shortcut: -corkscrew)
	       Display the corkscrew surface.

       -mode random (Shortcut: -random-mode)
	       Use random OpenGL primitives to display the surface.  This is the default.

       -mode points (Shortcut: -points)
	       Use OpenGL points to display the surface.

       -mode lines (Shortcut: -lines)
	       Use OpenGL lines to display the surface.

       -mode line-loops (Shortcut: -line-loops)
	       Use OpenGL line loops to display the surface.

       -wander | -no-wander
	       Whether to wander around the screen.

       -spin | -no-spin
	       Whether to rotate around the center of the figure.

       -fps    Display the current frame rate, CPU load, and polygon count.

ENVIRONMENT

       DISPLAY to get the default host and display number.

       XENVIRONMENT
	       to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.

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
