public class TransparencyAttributes extends NodeComponent
alphasrc*src +
(1-alphasrc)*dst
alphasrc is
1-transparency.
When this mode is used with a Raster object or with a Geometry
that contains per-vertex colors with alpha, the alpha values in
the Raster's image or in the Geometry's per-vertex colors are
combined with the transparency value in this TransparencyAttributes
object to perform blending. In this case, the alpha value used for
blending at each pixel is:
alphasrc =
alphapix *
(1-transparency).
