◆ xrif_difference_first()

xrif_error_t xrif_difference_first ( xrif_t handle )

Difference the images using the first image as a reference.

This function calls the type specific difference function for the type specified by handle->type_code.

Returns: XRIF_ERROR_NULLPTR if the handle is NULL; XRIF_ERROR_NOT_SETUP if the handle is not configured; XRIF_ERROR_INSUFFICIENT_SIZE if raw_buffer_size is not big enough given the configuration; XRIF_ERROR_NOTIMPL if differencing is not implemented for the type specified in xrif_handle::type_code; XRIF_NOERROR on success

xrif_error_t xrif_undifference_first ( xrif_t handle )

Undifference the images using the first image as a reference.

This function calls the type specific undifference function for the type specified by handle->type_code.

Returns: XRIF_ERROR_NULLPTR if the handle is NULL; XRIF_ERROR_NOT_SETUP if the handle is not configured; XRIF_ERROR_INSUFFICIENT_SIZE if raw_buffer_size is not big enough given the configuration; XRIF_ERROR_NOTIMPL if undifferencing is not implemented for the type specified in xrif_handle::type_code; XRIF_NOERROR on success
