Converting ImageProxy to Bitmap

by

You will need to check the image.format to see if it is ImageFormat.YUV_420_888. If so , then you can you use this extension to convert image to bitmap:

fun Image.toBitmap(): Bitmap {
    val yBuffer = planes[0].buffer // Y
    val vuBuffer = planes[2].buffer // VU

    val ySize = yBuffer.remaining()
    val vuSize = vuBuffer.remaining()

    val nv21 = ByteArray(ySize + vuSize)

    yBuffer.get(nv21, 0, ySize)
    vuBuffer.get(nv21, ySize, vuSize)

    val yuvImage = YuvImage(nv21, ImageFormat.NV21, this.width, this.height, null)
    val out = ByteArrayOutputStream()
    yuvImage.compressToJpeg(Rect(0, 0, yuvImage.width, yuvImage.height), 50, out)
    val imageBytes = out.toByteArray()
    return BitmapFactory.decodeByteArray(imageBytes, 0, imageBytes.size)
}

This works for a number of camera configurations. However, you might need to use a more advanced method that considers pixel strides.
