Struct exr::block::UncompressedBlock

source ·
pub struct UncompressedBlock {
    pub index: BlockIndex,
    pub data: ByteVec,
}
Expand description

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§

source§

impl UncompressedBlock

source

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

Decompress the possibly compressed chunk and returns an UncompressedBlock.

source

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

Consume this block by compressing it, returning a Chunk.

source

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.

source

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.

source

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.
