int dmxBECreateGlyphSet ( int  idx,
GlyphSetPtr  glyphSet 
)
int dmxBECreatePicture ( PicturePtr  pPicture  ) 

Create pPicture on the backend.

Referenced by dmxBERestoreRenderPict().

Bool dmxBEFreeGlyphSet ( ScreenPtr  pScreen,
GlyphSetPtr  glyphSet 
)
Bool dmxBEFreePicture ( PicturePtr  pPicture  ) 
void dmxChangePicture ( PicturePtr  pPicture,
Mask  mask 
)

Change the attributes of the pictures. If the picture has not yet been created due to lazy window creation, save the mask so that it can be used to appropriately initialize the picture's attributes when it is created later.

References DMX_GET_PICT_PRIV, DMX_UNWRAP, DMX_WRAP, dmxChangePicture(), dmxScreens, and _dmxPictPriv::savedMask.

Referenced by dmxChangePicture(), and dmxPictureInit().

int dmxChangePictureClip ( PicturePtr  pPicture,
int  clipType,
pointer  value,

)

Composite a picture on the appropriate screen by combining the specified rectangle of the transformed src and mask operands with the specified rectangle of the dst using op as the compositing operator. For a complete description see the protocol document of the RENDER library.

References _DMXScreenInfo::beDisplay, DMX_GET_PICT_PRIV, DMX_UNWRAP, DMX_WRAP, dmxComposite(), dmxScreens, dmxSync(), and _dmxPictPriv::pict.

Referenced by dmxCompositeRects(), and dmxPictureInit().

int dmxCreatePicture ( PicturePtr  pPicture  ) 

Create a picture. This function handles the CreatePicture unwrapping/wrapping and calls dmxDoCreatePicture to actually create the picture on the appropriate screen.

References DMX_GET_PICT_PRIV, DMX_UNWRAP, DMX_WRAP, dmxCreatePicture(), dmxDoCreatePicture(), dmxScreens, _dmxPictPriv::pict, and _dmxPictPriv::savedMask.

Referenced by dmxCreatePicture(), and dmxPictureInit().

void dmxCreatePictureList ( WindowPtr  pWindow  ) 

Create a list of pictures. This function is called by dmxCreateAndRealizeWindow() during the lazy window creation realization process. It creates the entire list of pictures that are associated with the given window.

References DMX_GET_PICT_PRIV, dmxDoCreatePicture(), and _dmxPictPriv::pict.

Referenced by dmxCreateAndRealizeWindow().

void dmxDestroyPicture ( PicturePtr  pPicture  ) 

Destroy a picture. This function calls the wrapped function that frees the resources in the DMX server associated with this picture.

References DMX_UNWRAP, DMX_WRAP, dmxBEFreePicture(), dmxDestroyPicture(), dmxScreens, and dmxSync().

Referenced by dmxDestroyPicture(), and dmxPictureInit().

void dmxDestroyPictureClip ( PicturePtr  pPicture  ) 
Bool dmxDestroyPictureList ( WindowPtr  pWindow  ) 

Destroy a list of pictures that are associated with the window that is being destroyed. This function is called by dmxDestroyWindow().

References dmxBEFreePicture().

void dmxGlyphs ( CARD8  op,
PicturePtr  pSrc,
PicturePtr  pDst,
PictFormatPtr  maskFormat,
INT16  xSrc,
INT16  ySrc,
int  nlists,
GlyphListPtr  lists,
GlyphPtr *  glyphs 
)

Null function to catch when/if RENDER calls lower level mi hooks. Compositing glyphs is handled by dmxProcRenderCompositeGlyphs(). This function should never be called.

Referenced by dmxPictureInit().

Bool dmxInitIndexed ( ScreenPtr  pScreen,
PictFormatPtr  pFormat 
)

Indexed color visuals are not yet supported.

void dmxInitRender ( void   ) 

Initialize the Proc Vector for the RENDER extension. The functions here cannot be handled by the mi layer RENDER hooks either because the required information is no longer available when it reaches the mi layer or no mi layer hooks exist. This function is called from InitOutput() since it should be initialized only once per server generation.

References dmxProcRenderAddGlyphs(), dmxProcRenderCompositeGlyphs(), dmxProcRenderCreateGlyphSet(), dmxProcRenderFreeGlyphs(), dmxProcRenderFreeGlyphSet(), dmxProcRenderSetPictureFilter(), dmxProcRenderSetPictureTransform(), dmxSaveRenderVector, and ProcRenderVector.

Referenced by InitOutput().

Bool dmxPictureInit ( ScreenPtr  pScreen,
PictFormatPtr  formats,
int  nformats 
)

Initialize the RENDER extension, allocate the picture privates and wrap mi function hooks. If the shadow frame buffer is used, then call the appropriate fb initialization function.

void dmxResetRender ( void   ) 

Reset the Proc Vector for the RENDER extension back to the original functions. This function is called from dmxCloseScreen() during the server reset (only for screen #0).
