Module exr::block::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.
