Hide the control if the alpha or scale is zero is not working! #95

Closed GoogleCodeExporter closed 9 years ago

Because Alpha is Single, sometimes Alpha=0 but the If (Alpha>=0) always returns 
True.

I have change from 0 to 0.001 and now is working! But I would like to know the 
correct way to do this! =)

    // Hide the control if the alpha or scale is zero
    Control.Visible:= (Scale >= 0) and (Alpha >= 0.001);

That's probably the way to do it, and same for scale.

Changed to this

 Control.Visible:= (Scale >= 0.01) and (Alpha >= 0.01);
