Function Documentation

void dmxBECreateGC (  ScreenPtr  pScreen, GCPtr  pGC )

Create the GC on the back-end server.

Bool dmxBEFreeGC (  GCPtr  pGC  )

Free the pGC on the back-end server.

void dmxChangeClip (  GCPtr  pGC, int  type, pointer  pvalue, int  nrects )

Change the clip rects for a GC.

void dmxChangeGC (  GCPtr  pGC, unsigned long  mask )

Set the values in the graphics context on the back-end server associated with pGC's screen.

void dmxCopyClip (  GCPtr  pGCDst, GCPtr  pGCSrc )

Copy a GC's clip rects.

void dmxCopyGC (  GCPtr  pGCSrc, unsigned long  changes, GCPtr  pGCDst )

Copy pGCSrc to pGCDst on the back-end server associated with pGCSrc's screen.

Bool dmxCreateGC (  GCPtr  pGC  )

Create a graphics context on the back-end server associated /a pGC's screen.

void dmxDestroyClip (  GCPtr  pGC  )

Destroy a GC's clip rects.

void dmxDestroyGC (  GCPtr  pGC  )

Destroy the graphics context, pGC and free the corresponding GC on the back-end server.

Bool dmxInitGC (  ScreenPtr  pScreen  )

Initialize the GC on pScreen, which currently involves allocating the GC private associated with this screen.

void dmxValidateGC (  GCPtr  pGC, unsigned long  changes, DrawablePtr  pDrawable )

Validate a graphics context, pGC, locally in the DMX server and recompute the composite clip, if necessary.
