17 SDL::PixelFormat - Stores surface format information
21 my $surface = SDL::Surface->new( ...
22 $surface->format; #this returns the PixelFormat object attached to this surface
24 PixelFormat is only created in a C<SDL::Surface>. This module only provides getters to the surface's pixelformat. Later on we will provide setting capability.
29 An C<SDL::PixelFormat > stores surface format information
35 $surface->format->palette;
37 Returns the C<SDL_Palette> and L<SDL::Palette> of the format of the surface.
41 $surface->format->BitsPerPixel;
43 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
47 $surface->format->BytesPerPixel;
49 The number of bytes used to represent each pixel in a surface. Usually one to four.
53 $surface->format->Rloss; #red loss
54 $surface->format->Bloss; #blue loss
55 $surface->format->Gloss; #green loss
56 $surface->format->Aloss; #alpha loss
58 Precision loss of each color component (2[RGBA]loss)
62 $surface->format->Rshift; #red shift
63 $surface->format->Bshift; #blue shift
64 $surface->format->Gshift; #green shift
65 $surface->format->Ashift; #alpha shift
67 Binary left shift of each color component in the pixel value
72 $surface->format->Rmask; #red mask
73 $surface->format->Bmask; #blue mask
74 $surface->format->Gmask; #green mask
75 $surface->format->Amask; #alpha mask
77 Binary left shift of each color component in the pixel value
81 $surface->format->colorkey;
83 Pixel value of transparent pixels.
87 $surface->format->alpha;
89 Overall surface alpha value
