    AddGlow Method
    In This Topic
    Creates a new bitmap by adding a glow to text and graphics on the current image.

    The glow effect inflates all non-transparent areas of an image by a specified amount, then applies a Gaussian blur to make the border smooth. The glow shows only where the pixels of the current image are transparent or semi-transparent.
