  const RectF & rect
);

Return value

If the method succeeds, it returns Ok, which is an element of the Status enumeration.

If the method fails, it returns one of the other elements of the Status enumeration.

Remarks

Examples

The following example sets a clipping region and updates the clipping region. It then draws rectangles to demonstrate the effective clipping region.

VOID Example_IntersectClip2(HDC hdc)
{
   Graphics graphics(hdc);

   // Set the clipping region.
   RectF clipRect(0.5f, 0.5f, 200.5f, 200.5f);
   graphics.SetClip(clipRect);

   // Update the clipping region to the portion of the rectangle that
   // intersects with the current clipping region.
   RectF intersectRect(100.5f, 100.5f, 200.5f, 200.5f);
   graphics.IntersectClip(intersectRect);

   // Fill a rectangle to demonstrate the effective clipping region.
   graphics.FillRectangle(&SolidBrush(Color(255, 0, 0, 255)), 0, 0, 500, 500);

   // Reset the clipping region to infinite.
   graphics.ResetClip();

   // Draw clipRect and intersectRect.
   graphics.DrawRectangle(&Pen(Color(255, 0, 0, 0)), clipRect);
   graphics.DrawRectangle(&Pen(Color(255, 255, 0, 0)), intersectRect);
}
