How to convert android.media.Image to bitmap object?

Question

In android, I get an Image object from here https://inducesmile.com/android/android-camera2-api-example-tutorial/ this camera tutorial. But I want to now loop through the pixel values, does anyone know how I can do that? Do I need to convert it to something else and how can I do that?

Thanks

If you want to loop all throughout the pixel then you need to convert it first to Bitmap object. Now since what I see in the source code that it returns an Image, you can directly convert the bytes to bitmap.

    Image image = reader.acquireLatestImage();
    ByteBuffer buffer = image.getPlanes()[0].getBuffer();
    byte[] bytes = new byte[buffer.capacity()];
    buffer.get(bytes);
    Bitmap bitmapImage = BitmapFactory.decodeByteArray(bytes, 0, bytes.length, null);

Then once you get the bitmap object, you can now iterate through all of the pixels.
