contentBytes

Decoded content-stream bytes (FlateDecode etc. applied). May be empty. If /Contents is an array, the chunks are concatenated with a separating newline (per ISO 32000-1 §7.8.2: "The effect is as if all of the streams in the array were concatenated"). A /Contents that is null or of a type no content can have is an empty page, which still draws its annotations (#583).
