Example
Run the CombineCommand on an image.

// Load an image

// Prepare the command

command.SourceImage = image.Clone();
// the rectangle that represents the affected area of the destination image.
command.DestinationRectangle = new LeadRect(image.Width / 8, image.Height / 8, image.Width, image.Height);
// The source point, which represents the source point of the source image which is to be combined.
