protected virtual AtalaImage ConstructFinalImage( AtalaImage image )
Protected Overridable Function ConstructFinalImage ( image As AtalaImage ) As AtalaImage
The default implementation returns a new image in the same pixel format as the source image.
The returned image must be the same size as the image passed in.
If it is not possible to allocate the image (for example, the pixel format is not know at this point), it is acceptable to return null. Returning null implies that the command will return a non-null image in PerformActualCommand.
If an error occurs, this method should throw an exception.
