I am using code to paint the NC area.  A consultant first changed the color.  We need round corners.  He got a message saying add transparency.  I did so and  it is not working correctly. 

1. It appears that you take the bitmap and stretch it to fill the area.  This distorts the rounding

2. Some areas are not rendered as transparent, apparently after the stretch, but are black.  Some areas are transparent and they are the same in the orginal bitmap

I need smooth rounded transparent corners.  How do I do this

I would like to attach files but cant see how to do this.

The width of rounded corners in pixels should be less than or equal to the width of left/right border.
