Parameters

bitmapData  IWritableBitmapData

The IWritableBitmapData to be cleared.

color  Color32

A Color32 that represents the desired result color of the bitmapData. If it has transparency, which is not supported by PixelFormat of bitmapData, then the result might be either completely transparent (depends also on AlphaThreshold), or the color will be blended with BackColor.

ditherer  IDitherer  (Optional)

The ditherer to be used for the clearing. Has no effect if PixelFormat of bitmapData has at least 24 bits-per-pixel size. This parameter is optional.
Default value: .

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.
