Copies a barcode component from another barcode component.
procedure Assign(Source: TPresistent); override;
If the Source parameter is an object created from a subclass of TBarcode2D component class, and the class is same to current barcode component class, Assign copies all property values and event handles except the Locked and the Image properties from the source barcode component to current one. If Source is any other type of object, an EBarcode2DError exception occurs.
