Struct exr::block::chunk::Chunk

pub struct Chunk {
    pub layer_index: usize,
    pub compressed_block: CompressedBlock,
}

A generic block of pixel information. Contains pixel data and an index to the corresponding header. All pixel data in a file is split into a list of chunks. Also contains positioning information that locates this data block in the referenced layer.

Fields

layer_index: usize

The index of the layer that the block belongs to. This is required as the pixel data can appear in any order in a file.

compressed_block: CompressedBlock

The compressed pixel contents.

Implementations

impl Chunk

Validation of chunks is done while reading and writing the actual data. (For example in exr::full_image)

pub fn write(&self, write: &mut impl Write, header_count: usize) -> UnitResult

Without validation, write this instance to the byte stream.

pub fn read(read: &mut impl Read, meta_data: &MetaData) -> Result<Self>

Read the value without validating.

Trait Implementations

impl Clone for Chunk

fn clone(&self) -> Chunk

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Chunk

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
