First overload creates a new empty image object.
Second overload creates a new image object of the specified size and format.
Third overload creates a new image object from another TIEVisionImage object.
Fourth overload creates a new image from the specified file. Currently supported file formats are: TIFF, JPEG, BMP, PNG, PXM, J2K (JPEG2000) and RAS.
Fifth overload creates a new image from the specified buffer (shares the same content). The buffer will be not released on destroy.
