A piece of clear glass is said to be totally transparent while a thick sheet of black cardboard is considered opaque you can t see through it at all . Opacity is a measurement of an object s transparency. In Flash an object s transparency value is called its Alpha value. If an object s Alpha value is set to 100 underlying objects can t be seen at all no light passes through an object with a 100 Alpha value. If the Alpha value of an object is set to 0 it becomes totally transparent you can t see the object . An object s Alpha value is an attribute of the object s color and is therefore available from the same Color panel that you use to change other color values. The Alpha value is an attribute of an object s color. When applying Alpha values less than 100 you should understand that the colors contained in a partially transparent object mix with the colors of any underlying objects. For example if you placed a partially transparent yellow object on top of a blue object the portions of the objects that overlap would appear green yellow blue green . The shade of green depends on the original colors as well as the transparency value of the uppermost object. 1. With open add a keyframe in Frame 30 of the Graduate layer. 2.
