HTML5 Canvas 3D WebGL (TM) javaScript Library
 

alpha Library Method

Short Description: Set Texture Opacity

Signature: t.alpha (a,a1)
Group: Texture
Class: transition Class
 

Sets the alpha, also called opacity, value of the texture of the transition. The background color is not effected. Values range from 0.0 (fully transparent) to 1.0 (fully visible). If two parameters are given then an animation from the first to the second alpha value is performed.

Examples

taccgl.actor("eximg").alpha(0.5).start(); RUN
taccgl.actor("eximg").alpha(0.5).bgColor("red").start(); RUN
taccgl.actor("eximg").alpha(0,1).start(); RUN
taccgl.actor("eximg").alpha(1,0).start(); RUN
taccgl.actor("eximg").alpha(1,0).bgColor("red").start(); RUN

The methods alpha and blend are mutually exclusive, the last one called is taking effect.
