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:


@:value(cast 8)@:impl@:enuminlineread onlyALPHA:BitmapDataChannel = 8

The alpha channel.

@:value(cast 4)@:impl@:enuminlineread onlyBLUE:BitmapDataChannel = 4

The blue channel.

@:value(cast 2)@:impl@:enuminlineread onlyGREEN:BitmapDataChannel = 2

The green channel.

@:value(cast 1)@:impl@:enuminlineread onlyRED:BitmapDataChannel = 1

The red channel.
