BufferedPaintClear function
Applies to: desktop apps only
Clears a specified rectangle in the buffer to ARGB = {0,0,0,0}.
Syntax
HRESULT BufferedPaintClear( HPAINTBUFFER hBufferedPaint, __in const RECT *prc );
Parameters
- hBufferedPaint
-
Type: HPAINTBUFFER
The handle of the buffered paint context, obtained through BeginBufferedPaint.
- prc [in]
-
Type: const RECT*
A pointer to a RECT structure that specifies the rectangle to clear. Set this parameter to NULL to specify the entire buffer.
Return value
Type: HRESULT
If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
This function accesses the buffer bits directly and is therefore faster than calling a GDI function to erase the buffer.
