7067312b |
210 | <p>Note 1: Use SDL_SWSURFACE if you plan on doing per-pixel manipulations, or blit surfaces with alpha channels, and require a high framerate. |
211 | When you use hardware surfaces (by passing the flag SDL_HWSURFACE as parameter), SDL copies the surfaces from video memory to system memory |
212 | when you lock them, and back when you unlock them. This can cause a major performance hit. Be aware that you may request a hardware surface, |
213 | but receive a software surface because the video driver doesn't support hardware surface. Many platforms can only provide a hardware surface |
214 | when using SDL_FULLSCREEN. The SDL_HWSURFACE flag is best used when the surfaces you'll be blitting can also be stored in video memory.</p> |
215 | <p>Note 2: If you want to control the position on the screen when creating a windowed surface, you may do so by setting the environment |
216 | variables SDL_VIDEO_CENTERED=center or SDL_VIDEO_WINDOW_POS=x,y. You can also set them via <code>SDL::putenv</code>.</p> |
162a0989 |
217 | <p>Note 3: This function should be called in the main thread of your application.</p> |
7067312b |
218 | <p>User note 1: Some have found that enabling OpenGL attributes like SDL_GL_STENCIL_SIZE (the stencil buffer size) before the video mode has |
219 | been set causes the application to simply ignore those attributes, while enabling attributes after the video mode has been set works fine.</p> |
220 | <p>User note 2: Also note that, in Windows, setting the video mode resets the current OpenGL context. You must execute again the OpenGL |
221 | initialization code (set the clear color or the shade model, or reload textures, for example) after calling SDL::set_video_mode. In Linux, |
222 | however, it works fine, and the initialization code only needs to be executed after the first call to SDL::set_video_mode (although there |
223 | is no harm in executing the initialization code after each call to SDL::set_video_mode, for example for a multiplatform application). </p> |

7067312b |
258 | <p>A software screen surface is also updated automatically when parts of a SDL window are redrawn, caused by overlapping windows or by |

289 | Non screen surfaces have a logical palette only. SDL::blit_surface always uses the logical palette when blitting surfaces (if it has to |

617 | <p>Returns the address of the GL function proc, or NULL if the function is not found. If the GL library is loaded at runtime, with |
618 | SDL::GL_load_library, then all GL functions must be retrieved this way. Usually this is used to retrieve function pointers to OpenGL |
619 | extensions. Note that this function needs an OpenGL context to function properly, so it should be called after SDL::set_video_mode |
620 | has been called (with the SDL_OPENGL flag).</p> |
621 | <p>OpenGL function pointers must be declared APIENTRY . This will ensure the proper calling convention is followed on platforms where this |
622 | matters (Win32) thereby avoiding stack corruption. In a Win32 build environment, APIENTRY should be defined as __stdcall. </p> |
