Struct PreparedClassicPlan 

pub struct PreparedClassicPlan { /* private fields */ }

Opaque retained classic JPEG 2000 execution plan for one prepared image.

Public callers inspect fragment byte ranges without depending on native implementation types. Backend crates use Self::adapter_view to borrow the immutable native geometry and segment metadata.

Implementations

impl PreparedClassicPlan

pub fn is_grayscale(&self) -> bool

Whether the retained geometry decodes one grayscale component.

pub fn is_color(&self) -> bool

Whether the retained geometry decodes three color components.

pub fn is_rgba(&self) -> bool

Whether the retained geometry decodes four components in R, G, B, A order.

pub fn payload_count(&self) -> usize

Number of referenced classic code-block payloads.

pub fn range_count(&self) -> usize

Number of encoded-input fragments across every code-block payload.

pub fn is_empty(&self) -> bool

Whether the plan has no referenced code-block payloads.

pub fn payload(&self, index: usize) -> Option<ClassicCodeBlockPayload>

Return one code-block payload descriptor by traversal index.

pub fn payloads( &self, ) -> impl ExactSizeIterator<Item = ClassicCodeBlockPayload> + '_

Iterate over code-block payload descriptors in component/step/job order.

pub fn range(&self, index: usize) -> Option<J2kCodestreamRange>

Return one original-input fragment range by flat index.

pub fn ranges(&self) -> impl ExactSizeIterator<Item = J2kCodestreamRange> + '_

Iterate over original-input fragment ranges in payload concatenation order.
