Configuration Kotlin

To configure Fotoapparat in Kotlin:

You can initialise an instance of FotoApparat like below. That's an example of fully adjusted configuration. Some values are optional.

Fotoapparat(
            context = this,
            view = cameraView,                   // view which will draw the camera preview
            scaleType = ScaleType.CenterCrop,    // (optional) we want the preview to fill the view
            lensPosition = back(),               // (optional) we want back camera
            cameraConfiguration = cameraConfiguration, // (optional) define an advanced configuration
            logger = loggers(                    // (optional) we want to log camera events in 2 places at once
                     logcat(),                   // ... in logcat
                     fileLogger(this)            // ... and to file
            ),
            cameraErrorCallback = { error -> }   // (optional) log fatal errors
    )

An example of fully adjusted camera configuration is shown below. All values are optional by default

val cameraConfiguration = CameraConfiguration(    
    pictureResolution = highestResolution(), // (optional) we want to have the highest possible photo resolution
    previewResolution = highestResolution(), // (optional) we want to have the highest possible preview resolution
    previewFpsRange = highestFps(),          // (optional) we want to have the best frame rate
    focusMode = firstAvailable(              // (optional) use the first focus mode which is supported by device
            continuousFocusPicture(),
            autoFocus(),                       // if continuous focus is not available on device, auto focus will be used
            fixed()                            // if even auto focus is not available - fixed focus mode will be used
    ),
    flashMode = firstAvailable(              // (optional) similar to how it is done for focus mode, this time for flash
            autoRedEye(),
            autoFlash(),
            torch(),
            off()
    ),
    antiBandingMode = firstAvailable(       // (optional) similar to how it is done for focus mode & flash, now for anti banding 
            auto(),
            hz50(),
            hz60(),
            none()
    ),
    jpegQuality = manualJpegQuality(90),     // (optional) select a jpeg quality of 90 (out of 0-100) values
    sensorSensitivity = lowestSensorSensitivity(), // (optional) we want to have the lowest sensor sensitivity (ISO)
    frameProcessor = { frame -> }            // (optional) receives each frame from preview stream
)
