I am working with the color object and weird things are happending when you
compare the transform aa value and the _alpha values. They should be
identical but they are not. The values seem to be identical at 0, 25, 75,
100 but inbetween, they clearly off the whole number values.
Here is an example:
//Box is a MovieClip on Stage
A = new Color(Box)
A.setRGB(0xFF0000) //turns the box red
Box._alpha = 20
Trace(a.getTransform().aa) // 19.921875 where it should be 20!
Box._alpha = 50
Trace(a.getTransform().aa) // 50 works fine!
Box._alpha = 60
Trace(a.getTransform().aa) // 59.765625 where it should be 60!
Box._alpha = 2
Trace(a.getTransform().aa) // 1.953125 where it should be 2!
Box._alpha = 95
Trace(a.getTransform().aa) // 94.921875 where it should be 95!
Box._alpha = 100
Trace(a.getTransform().aa) // 100 works fine!
Weird thing is if you do the opposite and use setTransform you get a
different alpha values in the movieClip itself. This looks like a player
error.
Player WIN 7,0,14,0
Anyone seen this before?
Thanks,
Ted ;)
