Definition in the specification
Table 89 · Additional Entries Specific to an Image Dictionary
ISO 32000-1:2008, §8.9.5.1 · PDF page 215 ↗
/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".
Qualifier: Optional
Conditional descriptions remain traceable. A definition alone does not implement a codec, a signature or every format mechanism. Read the coverage.
