photobot.Layer.overlay()

canvas.layers[i].overlay()
Description
Sets the blend mode of layer i to overlay. Overlaying is a combination of the multiply() command and the screen() command. Light pixels are screened, dark pixels are multiplied.
Overlay works significantly slower than multiply and screen, because it is a blend mode native to PhotoBot and not of the underlying Python Imaging Library.
Example
photobot = ximport("photobot") canvas = photobot.canvas(100,100) canvas.layer("robot.jpg") i = canvas.layer("newspaper.jpg") canvas.layers[i].overlay()
