Module writer

Composable structures to handle writing an image.

Structs

ChunkWriter

Can consume compressed pixel chunks, writing them a file. Use sequential_blocks_compressor or parallel_blocks_compressor to compress your data, or use compress_all_blocks_sequential or compress_all_blocks_parallel. Use on_progress to obtain a new writer that triggers a callback for each block.

OnProgressChunkWriter

A new writer that triggers a callback for each block written to the inner writer.

ParallelBlocksCompressor

Compress blocks to a chunk writer with multiple threads.

SequentialBlocksCompressor

Compress blocks to a chunk writer in this thread.

SortedBlocksWriter

Write blocks that appear in any order and reorder them before writing.

Traits

ChunksWriter

Write chunks to a byte destination. Then write each chunk with writer.write_chunk(chunk).

Functions

write_chunks_with

Write an exr file by writing one chunk after another in a closure. In the closure, you are provided a chunk writer, which should be used to write all the chunks. Assumes the your write destination is buffered.
