Parameters

bitmapData  IReadWriteBitmapData

The IReadWriteBitmapData to be transformed.

gamma  Single

A float value between 0 and 10, inclusive bounds. Values less than 1 decrease gamma correction, while values above 1 increase it.

ditherer  IDitherer  (Optional)

An optional IDitherer instance to dither the result of the transformation if the transformed colors are not compatible with the PixelFormat of the specified bitmapData. This parameter is optional.
Default value: .

channels  ColorChannels  (Optional)

The ColorChannels, on which the adjustment has to be performed. This parameter is optional.
Default value: Rgb.

asyncConfig  TaskConfig  (Optional)

The configuration of the asynchronous operation such as parallelization, cancellation, reporting progress, etc. When Progress is set in this parameter, then this library always passes a DrawingOperation instance to the generic methods of the IAsyncProgress interface. This parameter is optional.
Default value: .

Return Value

Usage Note

This method is not a blocking call even if the MaxDegreeOfParallelism property of the asyncConfig parameter is 1.
