       Parameters
           injpc Input JPEG2000 code stream.
           bufsize Length (in bytes) of the input JPEG2000 code stream.
           outfld Output matrix of grayscale image values.

       Returns

           • 0 Successful decode

           • -3 Error decode jpeg2000 code stream.

           • -5 decoded image had multiple color components. Only grayscale is expected.
