- bitmapData IReadableBitmapData
- The IReadableBitmapData to convert to grayscale.
- parallelConfig ParallelConfig
- The configuration of the 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.
If , then the degree of parallelization is configured automatically.
IReadWriteBitmapDataAn
IReadWriteBitmapData containing the grayscale version of the original
bitmapData, or
, if the operation
was canceled and the
ThrowIfCanceled property
of the
parallelConfig parameter was
.In Visual Basic and C#, you can call this method as an instance method on any object of type
IReadableBitmapData. When you use instance method syntax to call this method, omit the first parameter. For more information, see
Extension Methods (Visual Basic) or
Extension Methods (C# Programming Guide).
This method blocks the caller as it executes synchronously, though the
parallelConfig parameter allows configuring the degree of parallelism,
cancellation and progress reporting. Use the
BeginToGrayscale
or
ToGrayscaleAsync (in .NET Framework 4.0 and above) methods to perform the operation asynchronously.
This method always returns a new IReadWriteBitmapData with a pixel format matching the original color depth.
To make an IReadWriteBitmapData grayscale without creating a new instance use the MakeGrayscale method.
