BcmFingerImage

A scan result object is provided by BcmScanActivity or BcmScanFragment to IBcmFlowDelegate. It captures the result of a scan session.

Bitmap output format support for custom integration and projects.

Interface

data class BcmFingerImage(

    /**
     * The finger image data are represented as a bitmap.
     *
     * There are two image enhancement types
     * - defaultImage: optimized for matching algorithms
     * - nfiq2Image: optimized for nfiq2 observation
     */
    var defaultImage: Bitmap,
    var nfiq2Image: Bitmap,

    /**
     * The finger image - Dots Per Inch.
     */
    var dpi: Double,

    /**
     * This data point is not implemented yet and can be ignored.
     */
    var distance: Double,

    /**
     * Contains the score of the captured finger.
     * The range is between [0.0 - 1.0]. Good acceptable values are around 0.2.
     * 0.5 - 1.0 is hard to reach, but theoretically possible.
     */
    var score: Double,

    /**
     * Info about which Hand - Left, Right
     */
    var hand: Hand,

    /**
     * Info about which Finger - Thumb, Index, Middle, Ring, Pinky
     */
    var finger: Finger)

Usage

BcmFingerImage is used for the IBcmFlowDelegate.fingerImagesResult() callback, when the scan gets terminated. The scan termination can be configured via the BcmScanConfig.

There is also the possibility to set your own Scan termination logic, see Custom Scan Termination.
