/Decode array
(Optional) An array of numbers describing how to map image samples into the range of values appropriate for the image’s colour space (see 8.9.5.2, "Decode Arrays"). If ImageMask is true, the array shall be either [ 0 1 ] or [ 1 0 ]; otherwise, its length shall be twice the number of colour components required by ColorSpace. If the image uses the JPXDecode filter and ImageMask is false, Decode shall be ignored by a conforming reader. Default value: see 8.9.5.2, "Decode Arrays".
