Module exr::block::reader

Composable structures to handle reading an image.

Structs

• AllChunksReader
  Decode all chunks in the file without seeking. The decoded chunks can be decompressed by calling decompress_parallel, decompress_sequential, or sequential_decompressor or parallel_decompressor. Call on_progress to have a callback with each block. Also contains the image meta data.
• FilteredChunksReader
  Decode the desired chunks and skip the unimportant chunks in the file. The decoded chunks can be decompressed by calling decompress_parallel, decompress_sequential, or sequential_decompressor or parallel_decompressor. Call on_progress to have a callback with each block. Also contains the image meta data.
• OnProgressChunksReader
  Decode chunks in the file without seeking. Calls the supplied closure for each chunk. The decoded chunks can be decompressed by calling decompress_parallel, decompress_sequential, or sequential_decompressor. Also contains the image meta data.
• ParallelBlockDecompressor
  Decompress the chunks in a file in parallel. The first call to next will fill the thread pool with jobs, starting to decompress the next few blocks. These jobs will finish, even if you stop reading more blocks. Implements iterator.
• Reader
  Decode the meta data from a byte source, keeping the source ready for further reading. Continue decoding the remaining bytes by calling filtered_chunks or all_chunks.
• SequentialBlockDecompressor
  Read all chunks from the file, decompressing each chunk immediately. Implements iterator.

Traits

• ChunksReader
  Decode chunks in the file. The decoded chunks can be decompressed by calling decompress_parallel, decompress_sequential, or sequential_decompressor. Call on_progress to have a callback with each block. Also contains the image meta data.
