Enum J2kFileColorSpec 

#[non_exhaustive]
pub enum J2kFileColorSpec<'a> {
    Infer,
    Enumerated(Colorspace),
    IccProfile(&'a [u8]),
}

Color metadata to write into a JP2/JPH Colour Specification box.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Infer

Infer an enumerated JP2 colorspace from the codestream component count and parsed JPEG 2000 color transform metadata.

Enumerated(Colorspace)

Write an enumerated JP2 colorspace.

IccProfile(&'a [u8])

Write an ICC-profile Colour Specification box.

Implementations
