	ref ImageResults results
)

Parameters

source
Type: Atalasoft.ImagingAtalaImage
The source image for processing. This may be different from the original image.
dest
Type: Atalasoft.ImagingAtalaImage
The destination image. Dest will be null when InPlaceProcessing is true or when ConstructFinalImage returns null.
imageArea
Type: System.DrawingRectangle
An area of the source image to process. When the destination image is non-null, it will always be the same size as imageArea. ImageArea only differs in size from the source image when the command is a subclass of ImageRegionCommand and when there is a region of interest.
results
Type: Atalasoft.Imaging.ImageProcessingImageResults
The results object that will be used for this command.

Return Value

Type: AtalaImage
In most cases, PerformActualCommand should return null. When PerformActualCommand returns a non-null image, it is indicating that it has allocated a new image to use for the final image. This must be true if ConstructFinalImage returned null.
