Members

GenericSensorCapabilities

The generic capabilities of the sensor component that is connected to a specific biometric unit.

Factor

The type of biometric unit for which this structure contains information about capabilities and enrollment requirements of the sensor adapter. For example, if the value of the Factor member is WINBIO_TYPE_FINGERPRINT, the WINBIO_EXTENDED_SENSOR_INFO structure applies to a fingerprint reader and contains the relevant information in the Specifc.Fingerprint structure.

Specific

Information about the capabilities and enrollment requirements of the sensor adapter for a biometric unit related to a specific biometric factor.

Null

Reserved. Must be zero.

FacialFeatures

Information about the capabilities and enrollment requirements of the sensor adapter for a biometric unit related to facial features.

FrameSize

The size of the camera frame, indicated as a length and width in pixels by the right and bottom members of the RECT structure. The point (0, 0) represents the top-left corner of the frame.

FrameOffset

The offset of the camera frame for the face from the video camera, in pixels. A value of (0, 0) indicates that the camera frame for the face and the video camera completely overlap.

MandatoryOrientation

The preferred orientation for the camera.

Fingerprint

Information about the capabilities and enrollment requirements of the sensor adapter for a biometric unit related to fingerprint patterns.

Reserved

Reserved.

Iris

Information about the capabilities and enrollment requirements of the sensor adapter for a biometric unit related to iris patterns.

FrameSize

The size of the camera frame, indicated as a length and width in pixels by the right and bottom members of the RECT structure. The point (0, 0) represents the top-left corner of the frame.

FrameOffset

The offset of the camera frame for the iris from the video camera, in pixels. A value of (0, 0) indicates that the camera frame for the iris and the video camera completely overlap.

MandatoryOrientation

The preferred orientation for the camera.

Voice

Information about the capabilities and enrollment requirements of the sensor adapter for a biometric unit related to voice patterns.

Reserved

Reserved.
