The BitmapDataChannel class is an enumeration of constant values that indicate which channel to use: red, blue, green, or alpha transparency.

When you call some methods, you can use the bitwise OR operator (|) to combine BitmapDataChannel constants to indicate multiple color channels.

The BitmapDataChannel constants are provided for use as values in the following:
