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:

- The `sourceChannel` and `destChannel` parameters of the `flash.display.BitmapData.copyChannel()` method
- The `channelOptions` parameter of the `flash.display.BitmapData.noise()` method
- The `flash.filters.DisplacementMapFilter.componentX` and `flash.filters.DisplacementMapFilter.componentY` properties
