# photobot.Layer.multiply()

## Syntax

    canvas.layers[i].multiply()

## Description

Sets the blend mode of layer i to multiply. Multiplying an underlying image with black results in black, multiplying with white leaves the image unchanged. So multiply usually returns a darker result.

## Example

    photobot = ximport("photobot")
    canvas = photobot.canvas(100,100)
    canvas.layer("robot.jpg")
    i = canvas.layer("newspaper.jpg")
    canvas.layers[i].multiply()
