Oh, you mean a gradient on the alpha channel. It is not really possible without making the code more complex and I think significantly slower. A coarse gradient between the different vertical bands is easy, but the alpha must be constant in each band, just like the color. A gradient on the undulating diagonal line is possible and easy, OTOH, since it already has a color gradient. What do you think? Regards, -- Nicolas George
