Struct exr::block::UncompressedBlock

pub struct UncompressedBlock {
    pub index: BlockIndex,
    pub data: ByteVec,
}

Contains a block of pixel data and where that data should be placed in the actual image.

Fields

index: BlockIndex

Location of the data inside the image.

data: ByteVec

Uncompressed pixel values of the whole block. One or more scan lines may be stored together as a scan line block. This byte vector contains all pixel rows, one after another. For each line in the tile, for each channel, the row values are contiguous. Stores all samples of the first channel, then all samples of the second channel, and so on.

Implementations

impl UncompressedBlock

pub fn decompress_chunk( chunk: Chunk, meta_data: &MetaData, pedantic: bool, ) -> Result<Self>

Decompress the possibly compressed chunk and returns an UncompressedBlock.

pub fn compress_to_chunk(self, headers: &[Header]) -> Result<Chunk>

Consume this block by compressing it, returning a Chunk.

pub fn lines(&self, channels: &ChannelList) -> impl Iterator<Item = LineRef<'_>>

Iterate all the lines in this block. Each line contains the all samples for one of the channels.

pub fn collect_block_data_from_lines( channels: &ChannelList, block_index: BlockIndex, extract_line: impl FnMut(LineRefMut<'_>), ) -> Vec<u8>

Create an uncompressed block byte vector by requesting one line of samples after another.

pub fn from_lines( channels: &ChannelList, block_index: BlockIndex, extract_line: impl FnMut(LineRefMut<'_>), ) -> Self

Create an uncompressed block by requesting one line of samples after another.

Trait Implementations

impl Clone for UncompressedBlock

fn clone(&self) -> UncompressedBlock

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UncompressedBlock

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

Formats the value using the given formatter.

impl PartialEq for UncompressedBlock

fn eq(&self, other: &UncompressedBlock) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
