1 .TH "SDL_SetVideoMode" "3" "Sun 10 Jun 2001, 19:42" "SDL" "SDL API Reference" |
| 0 | 2 .SH "NAME" |
| 3 SDL_SetVideoMode\- Set up a video mode with the specified width, height and bits-per-pixel\&. | |
| 4 .SH "SYNOPSIS" | |
| 5 .PP | |
| 6 \fB#include "SDL\&.h" | |
| 7 .sp | |
| 8 \fBSDL_Surface *\fBSDL_SetVideoMode\fP\fR(\fBint width, int height, int bpp, Uint32 flags\fR); | |
| 9 .SH "DESCRIPTION" | |
| 10 .PP | |
| 11 Set up a video mode with the specified width, height and bits-per-pixel\&. | |
| 12 .PP | |
| 13 If \fBbpp\fR is 0, it is treated as the current display bits per pixel\&. | |
| 14 .PP | |
| 15 The \fBflags\fR parameter is the same as the \fBflags\fR field of the \fI\fBSDL_Surface\fR\fR structure\&. OR\&'d combinations of the following values are valid\&. | |
| 16 .TP 20 | |
| 17 \fBSDL_SWSURFACE\fP | |
| 18 Create the video surface in system memory | |
| 19 .TP 20 | |
| 20 \fBSDL_HWSURFACE\fP | |
| 21 Create the video surface in video memory | |
| 22 .TP 20 | |
| 23 \fBSDL_ASYNCBLIT\fP | |
| 24 Enables the use of asynchronous to the display surface\&. This will usually slow down blitting on single CPU machines, but may provide a speed increase on SMP systems\&. | |
| 25 .TP 20 | |
| 26 \fBSDL_ANYFORMAT\fP | |
| 27 Normally, if a video surface of the requested depth (\fBbpp\fR) is not available, SDL will emulate one with a shadow surface\&. Passing \fBSDL_ANYFORMAT\fP prevents this and causes SDL to use the video surface, regardless of its depth\&. | |
| 28 .TP 20 | |
| 29 \fBSDL_HWPALETTE\fP | |
| 30 Give SDL exclusive palette access\&. Without this flag you may not always get the the colors you request with \fI\fBSDL_SetColors\fP\fR\&. | |
| 31 .TP 20 | |
| 32 \fBSDL_DOUBLEBUF\fP | |
|

33 Enable double buffering; only valid with SDL_HWSURFACE\&. Calling \fI\fBSDL_Flip\fP\fR will flip the buffers and update the screen\&. If double buffering could not be enabled then \fBSDL_Flip\fP will just perform a \fI\fBSDL_UpdateRect\fP\fR on the entire screen\&. |
| 0 | 34 .TP 20 |
| 35 \fBSDL_FULLSCREEN\fP | |
| 36 SDL will attempt to use a fullscreen mode | |
| 37 .TP 20 | |
| 38 \fBSDL_OPENGL\fP | |
| 39 Create an OpenGL rendering context\&. You should have previously set OpenGL video attributes with \fI\fBSDL_GL_SetAttribute\fP\fR\&. | |
| 40 .TP 20 | |
| 41 \fBSDL_OPENGLBLIT\fP | |
| 42 Create an OpenGL rendering context, like above, but allow normal blitting operations\&. | |
| 43 .TP 20 | |
| 44 \fBSDL_RESIZABLE\fP | |
| 45 Create a resizable window\&. When the window is resized by the user a \fI\fBSDL_VIDEORESIZE\fP\fR event is generated and \fBSDL_SetVideoMode\fP can be called again with the new size\&. | |
| 46 .TP 20 | |
| 47 \fBSDL_NOFRAME\fP | |
| 48 If possible, \fBSDL_NOFRAME\fP causes SDL to create a window with no title bar or frame decoration\&. Fullscreen modes automatically have this flag set\&. | |
| 49 .PP | |
| 50 .RS | |
| 51 \fBNote: | |
| 52 .PP | |
| 53 Whatever \fBflags\fR \fBSDL_SetVideoMode\fP could satisfy are set in the \fBflags\fR member of the returned surface\&. | |
| 54 .RE | |
| 55 .SH "RETURN VALUE" | |
| 56 .PP | |
| 57 The framebuffer surface, or \fBNULL\fR if it fails\&. | |
| 58 .SH "SEE ALSO" | |
| 59 .PP | |
| 60 \fI\fBSDL_LockSurface\fP\fR, \fI\fBSDL_SetColors\fP\fR, \fI\fBSDL_Flip\fP\fR, \fI\fBSDL_Surface\fR\fR | |
