            - This routine can save images containing any type of pixel.  However,
              save_webp() can only natively store rgb_pixel, bgr_pixel, rgb_alpha_pixel and
              bgr_alpha_pixel pixel types.  All other pixel types will be converted into one
              of these types as appropriate before being saved to disk.
            - The quality value determines how lossy the compression is.  Larger quality
              values result in larger output images but the images will look better.  A value
              between 0 and 100 will use lossy compression, while any value larger than
              100 will perform lossless compression.

                This exception is thrown if there is an error that prevents us from saving
                the image.
