Integer
value
13 "overlay" Adjusts the color of each bitmap
based on the darkness of the
background. If the background is
lighter than 50% gray, the button and
background colors are screened,
which results in a lighter color. If the
background is darker than 50% gray,
the colors are multiplied, which results
in a darker color. This setting is
commonly used for shading effects.
14 "hardlight" Adjusts the color of each bitmap
based on the darkness of the button. If
the button is lighter than 50% gray,
the button and background colors are
screened, which results in a lighter
color. If the button is darker than 50%
gray, the colors are multiplied, which
results in a darker color. This setting is
commonly used for shading effects.
If you attempt to set the blendMode property to any other value, Flash Player sets it to
"normal".
Availability: ActionScript 1.0; Flash Player 8
Example
In the following example you can see that if you set the property to an integer, Flash Player
converts the value to the corresponding string version:
my_button.blendMode = 8;
trace (my_button.blendMode) // add
For a related example, see the description of the blendMode property of the MovieClip class.

public cacheAsBitmap : Boolean
If set to true, Flash Player caches an internal bitmap representation of the button. This can
increase performance for buttons that contain complex vector content.
