-     *         smaller than original bitmap, sampling 1 pixel for
-     *         every size pixels. e.g. if sample size is set to 3,
-     *         then the returned bitmap will be 1/3 as wide and high,
-     *         and will contain 1/9 as many pixels as the original.
-     *         Note: this is a hint, and the codec may choose to
-     *         ignore this, or only approximate the sample size.
-     *
-     *  @param fDitherImage Set to true if the the decoder should try to
-     *         dither the resulting image when decoding to a smaller
-     *         color-space.  The default is true.
-     *

-     *         config the decoder wants.  Else try to use this color
-     *         type.  If the decoder won't support this color type,
-     *         SkDecodingImageGenerator::Create will return
-     *         NULL. kIndex_8_SkColorType is not supported.
-     *
-     *  @param fRequireUnpremul If true, the decoder will attempt to
-     *         decode without premultiplying the alpha. If it cannot,
-     *         the pixels will be set to NULL.
