BitmapDataExtensionsMakeOpaqueAsync Method

Makes this bitmapData opaque asynchronously using the specified backColor.


Namespace: KGySoft.Drawing.Imaging
Assembly: KGySoft.Drawing.Core (in KGySoft.Drawing.Core.dll) Version: 8.1.0
public static Task MakeOpaqueAsync(
	this IReadWriteBitmapData bitmapData,
	Color32 backColor,
	IDitherer? ditherer = null,
	TaskConfig? asyncConfig = null


bitmapData  IReadWriteBitmapData
The IReadWriteBitmapData to make opaque.
backColor  Color32
Pixels with alpha in bitmapData will be blended with this color. The Color32.A property of the specified color is ignored.
ditherer  IDitherer  (Optional)
An optional IDitherer instance to dither the result of the transformation if the inverse of the bitmapData has no exact representation with its PixelFormat. 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

A Task that represents the asynchronous operation, which could still be pending.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IReadWriteBitmapData. When you use instance method syntax to call this method, omit the first parameter.
