Struct J2kView 

pub struct J2kView<'a> { /* private fields */ }

Borrowed parse result for a JP2 or raw JPEG 2000 / HTJ2K codestream.

Use this when a caller wants to inspect metadata once and build a decoder later without copying compressed tile bytes.

Implementations

impl<'a> J2kView<'a>

pub fn parse(input: &'a [u8]) -> Result<Self, J2kError>

Parse container/codestream metadata into a borrowed view.

Errors

Returns J2kError when the input is not a supported JP2/J2C/HTJ2K stream or when backend inspection rejects the codestream.

pub fn parse_with_settings( input: &'a [u8], settings: DecodeSettings, ) -> Result<Self, J2kError>

Parse container/codestream metadata with a per-image validation policy.

DecodeSettings::default is strict. Explicit lenient mode is limited to the JP2/JPH metadata recoveries documented by DecodeSettings::lenient.

Errors

Returns J2kError when the input is unsupported or malformed outside the selected policy’s documented recovery boundary.

pub fn info(&self) -> &Info

Header-derived image metadata.

pub fn support_info(&self) -> Option<&J2kSupportInfo>

Full JPEG 2000 / HTJ2K support metadata when header parsing classified the payload without falling back to backend-only inspection.

pub fn bytes(&self) -> &'a [u8]

Original compressed bytes backing this view.

pub fn passthrough_candidate(&self) -> Option<PassthroughCandidate<'a>>

Return a byte-preserving passthrough candidate when the native parser classified the compressed syntax and payload shape.
