/**

 * The {@link DngCreator} class provides functions to write raw pixel data as a DNG file.

 *

 * <p>

 * This class is designed to be used with the {@link android.graphics.ImageFormat#RAW_SENSOR}

 * buffers available from {@link android.hardware.camera2.CameraDevice}, or with Bayer-type raw

 * pixel data that is otherwise generated by an application.  The DNG metadata tags will be

 * generated from a {@link android.hardware.camera2.CaptureResult} object or set directly.

 * </p>

 *

 * <p>

 * The DNG file format is a cross-platform file format that is used to store pixel data from

 * camera sensors with minimal pre-processing applied.  DNG files allow for pixel data to be

 * defined in a user-defined colorspace, and have associated metadata that allow for this

 * pixel data to be converted to the standard CIE XYZ colorspace during post-processing.

 * </p>

 *

 * <p>

 * For more information on the DNG file format and associated metadata, please refer to the

 * <a href=

 * "https://wwwimages2.adobe.com/content/dam/Adobe/en/products/photoshop/pdfs/dng_spec_1.4.0.0.pdf">
