Parameters

source  IReadableBitmapData

The source IReadableBitmapData to be drawn into the target.

target  IReadWriteBitmapData

The target IReadWriteBitmapData into which source should be drawn.

context  IAsyncContext

An IAsyncContext instance that contains information for asynchronous processing about the current operation.

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.

Return Value

Usage Note

This method blocks the caller thread but if context belongs to an async top level method, then the execution may already run on a pool thread. Degree of parallelism, the ability of cancellation and reporting progress depend on how these were configured at the top level method.

When reporting progress, this library always passes a DrawingOperation instance to the generic methods of the IAsyncProgress interface.
