FillDrawPixelInfo() [2/2]

bool FillDrawPixelInfo	(	DrawPixelInfo *	n,
		int	left,
		int	top,
		int	width,
		int	height
	)

Set up a clipping area for only drawing into a certain area.

To do this, Fill a DrawPixelInfo object with the supplied relative rectangle, backup the original (calling) _cur_dpi and assign the just returned DrawPixelInfo _cur_dpi. When you are done, give restore _cur_dpi's original value

Parameters

*n	the DrawPixelInfo that will be the clipping rectangle box allowed for drawing
left,top,width,height	the relative coordinates of the clipping rectangle relative to the current _cur_dpi. This will most likely be the offset from the calling window coordinates

Returns
