Chapter 6. Deeper into Graphics > The alpha channel

The alpha channel

Alpha away!

Director's alpha channel support means you can improve your graphics and create some outstanding effects.


For you Director users who are into the graphics side of creating movies, Director's alpha channel support, introduced with Director 7, will be a welcome addition. If you're into graphics, you've probably been using alpha channels all along in other graphics packages such as Photoshop or Freehand. For those of you who are new to alpha channels, it means there is an additional amount of information for each pixel of an image. This additional information defines the degree of transparency for the individual pixels. Previously, when you imported an image with an alpha channel, the information was lost on Director. Now you can include the alpha channel to improve your graphics and create some outstanding effects.
