Trait exr::image::read::layers::ChannelsReader

pub trait ChannelsReader {
    type Channels;

    fn filter_block(&self, tile: TileCoordinates) -> bool;
    fn read_block(
        &mut self, 
        header: &Header, 
        block: UncompressedBlock
    ) -> UnitResult;
    fn into_channels(self) -> Self::Channels;
}

Processes pixel blocks from a file and accumulates them into multiple channels per layer.

Required Associated Types

type Channels

The type of the resulting channel collection

Required Methods

fn filter_block(&self, tile: TileCoordinates) -> bool

Specify whether a single block of pixels should be loaded from the file

fn read_block(
    &mut self,
    header: &Header,
    block: UncompressedBlock
) -> UnitResult

Load a single pixel block, which has not been filtered, into the reader, accumulating the channel data

fn into_channels(self) -> Self::Channels

Deliver the final accumulated channel collection for the image
