    /**

     * Free the native object associated with this bitmap, and clear the

     * reference to the pixel data. This will not free the pixel data synchronously;

     * it simply allows it to be garbage collected if there are no other references.

     * The bitmap is marked as "dead", meaning it will throw an exception if

     * getPixels() or setPixels() is called, and will draw nothing. This operation

     * cannot be reversed, so it should only be called if you are sure there are no

     * further uses for the bitmap. This is an advanced call, and normally need

     * not be called, since the normal GC process will free up this memory when

     * there are no more references to this bitmap.

     * Immediately releases the pixel data associated with this Bitmap.

     *

     * <p>Call this method to release a Bitmap that is certainly no longer needed, such as with a

     * Bitmap that was created as an intermediate buffer in a transformation. Calling this

     * method will release the pixel memory immediately, rather than wait for a future Garbage

     * Collection.

     * <p>Avoid calling this method on Bitmaps that were used in a View or that may be referenced

     * elsewhere, as it may be unsafe.

     *

     * <p>After calling this method, any subsequent attempt to access the bitmap's pixel data

     * (e.g., using {@code getPixels()} or {@code setPixels()}) will throw an exception, and the

     * bitmap will draw nothing. This operation cannot be reversed.
