enum abstract BitmapDataChannel(Int)

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 openfl.display.BitmapData.copyChannel() method
• The channelOptions parameter of the openfl.display.BitmapData.noise() method
• The openfl.filters.DisplacementMapFilter.componentX and openfl.filters.DisplacementMapFilter.componentY properties
