Parameters

source  IReadableBitmapData

The source IReadableBitmapData to be drawn into the target.

target  IReadWriteBitmapData

The target IReadWriteBitmapData into which source should be drawn.

sourceRectangle  Rectangle

A Rectangle that specifies the portion of the source to be drawn into the target.

targetRectangle  Rectangle

A Rectangle that specifies the location and size of the drawn source.

quantizer  IQuantizer  (Optional)

An IQuantizer instance to be used for the drawing. If not specified, then the drawing operation might automatically pick a quantizer based on target PixelFormat. This parameter is optional.
Default value: .

ditherer  IDitherer  (Optional)

The ditherer to be used for the drawing. Might be ignored if quantizer is not specified and target PixelFormat format has at least 24 bits-per-pixel size. This parameter is optional.
Default value: .

scalingMode  ScalingMode  (Optional)

Specifies the scaling mode if the bitmap data to be drawn needs to be resized. This parameter is optional.
Default value: Auto.

asyncConfig  AsyncConfig  (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

In .NET Framework 4.0 and above you can use also the DrawIntoAsync(IReadableBitmapData, IReadWriteBitmapData, Rectangle, Rectangle, IQuantizer, IDitherer, ScalingMode, TaskConfig) method.

To finish the operation and to get the exception that occurred during the operation you have to call the EndDrawInto method.

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