Sets the verification parameters in the supplied context.
| Prerequisites | The Fingerprint SDK library must have been previously initialized. |
| Return | On success, GR_OK is returned. If any supplied parameter is invalid or out of range, its default value will be used and GR_DEFAULT_USED is returned. On failure, the appropriate error code is returned. |
| [in] verifyThreshold |
The verification score threshold. |
| [in] verifyRotationTolerance |
The rotation tolerance for the verification process. |
| [in] context |
Context in which the verification parameters will be set. |
