MovieClip 841

The following table describes the blendMode settings. To set the blendMode property, you can

use either an integer from 1 to 14 or a string. The illustrations in the table show

blendMode

values applied to a circular movie clip (2) superimposed on another onscreen object (1).

Integer value String value Illustration Description

1 "normal" The movie clip appears in front of the

background. Pixel values of the movie clip

override those of the background. Where

the movie clip is transparent, the

background is visible.

"layer" Forces the creation of a temporary buffer

for precomposition for the movie clip. This

is done automatically if there is more than

one child object in a movie clip and a

blendMode setting other than "normal" is

selected for the child.

"multiply" Multiplies the values of the movie clip

constituent colors by those of the

background color, and then normalizes by

dividing by 0xFF, resulting in darker colors.

This setting is commonly used for shadows

and depth effects.

For example, if a constituent color (such as

red) of one pixel in the movie clip and the

corresponding color of the pixel in the

background both have the value 0x88, the

multiplied result is 0x4840. Dividing by

0xFF yields a value of 0x48 for that

constituent color, which is a darker shade

than that of the movie clip or that of the

background.
