The following code sample shows a function that sets the pixel format using Win32 functions:
BOOL bSetupPixelFormat(HDC hdc)
{
PIXELFORMATDESCRIPTOR pfd, *ppfd;
int pixelformat;
ppfd = &pfd;
ppfd->nSize = sizeof(PIXELFORMATDESCRIPTOR);
ppfd->nVersion = 1;
ppfd->dwFlags = PFD_DRAW_TO_WINDOW | PFD_SUPPORT_OPENGL |
PFD_DOUBLEBUFFER;
ppfd->dwLayerMask = PFD_MAIN_PLANE;
ppfd->iPixelType = PFD_TYPE_COLORINDEX;
ppfd->cColorBits = 8;
ppfd->cDepthBits = 16;
ppfd->cAccumBits = 0;
ppfd->cStencilBits = 0;
pixelformat = ChoosePixelFormat(hdc, ppfd);
if ( (pixelformat = ChoosePixelFormat(hdc, ppfd)) == 0 )
{
MessageBox(NULL, "ChoosePixelFormat failed", "Error", MB_OK);
return FALSE;
}
if (SetPixelFormat(hdc, pixelformat, ppfd) == FALSE)
{
MessageBox(NULL, "SetPixelFormat failed", "Error", MB_OK);
return FALSE;
}
return TRUE;
}
