Comments

If you override this function, you must supply the image data that the function will save. The base class implementation saves data from the class object's associated bitmap.

This function does not support signed data images, unless they are DICOM images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image that is not a DICOM image is passed to this function.
