fpi_imgdev_abort_scan ()

void
fpi_imgdev_abort_scan (struct fp_img_dev *imgdev,
                       int result);

Aborts a scan after an error, and set the action result. See fpi_imgdev_get_action_result() for possible values.

fpi_imgdev_activate_complete ()

void
fpi_imgdev_activate_complete (struct fp_img_dev *imgdev,
                              int status);

Marks an activation as complete, whether successful or not. See fpi_imgdev_get_action_result() for possible values.

fpi_imgdev_close_complete ()

void
fpi_imgdev_close_complete (struct fp_img_dev *imgdev);

Function to call when the device has been closed.

fpi_imgdev_deactivate_complete ()

void
fpi_imgdev_deactivate_complete (struct fp_img_dev *imgdev);

Marks a deactivation as complete.

fpi_imgdev_get_action ()

enum fp_imgdev_action
fpi_imgdev_get_action (struct fp_img_dev *imgdev);

Returns the current action being performed by an imaging device.

fpi_imgdev_get_action_result ()

int
fpi_imgdev_get_action_result (struct fp_img_dev *imgdev);

Returns an integer representing the result of an action. Which enum the result code is taken from depends on the current action being performed. See fp_capture_result, fp_enroll_result and fp_verify_result.

fpi_imgdev_get_action_state ()

enum fp_imgdev_enroll_state
fpi_imgdev_get_action_state (struct fp_img_dev *imgdev);

Returns the state of an imaging device while enrolling a fingerprint.

fpi_imgdev_image_captured ()

void
fpi_imgdev_image_captured (struct fp_img_dev *imgdev,
                           struct fp_img *img);

Report to the core that the driver captured this image from the sensor.

fpi_imgdev_open_complete ()

void
fpi_imgdev_open_complete (struct fp_img_dev *imgdev,
                          int status);

Function to call when the device has been opened, whether successfully of not.

fpi_imgdev_report_finger_status ()

void
fpi_imgdev_report_finger_status (struct fp_img_dev *imgdev,
                                 gboolean present);

Reports from the driver whether the user's finger is on the sensor.

fpi_imgdev_session_error ()

void
fpi_imgdev_session_error (struct fp_img_dev *imgdev,
                          int error);

Report an error that occurred in the driver.

fpi_imgdev_set_action_result ()

void
fpi_imgdev_set_action_result (struct fp_img_dev *imgdev,
                              int action_result);

Drivers should use fpi_imgdev_image_captured() instead. This function should not be used, and will be removed soon.

enum fp_imgdev_action

The current action being performed by an imaging device. The current action can be gathered inside the driver using fpi_imgdev_get_action().

enum fp_imgdev_state

The state of an imaging device while doing a capture. The state is passed through to the driver using the ::activate() or ::change_state() vfuncs.

enum fp_imgdev_enroll_state

The state of an imaging device while enrolling a fingerprint. Given that enrollment requires multiple captures, a number of those states will be repeated before the state is IMG_ACQUIRE_STATE_DONE .
