Structs§

  • Chunk
    A generic block of pixel information. Contains pixel data and an index to the corresponding header. All pixel data in a file is split into a list of chunks. Also contains positioning information that locates this data block in the referenced layer.
  • CompressedDeepScanLineBlock
    This Block consists of one or more deep scan lines. Corresponds to type attribute deepscanline.
  • CompressedDeepTileBlock
    This Block is a tile of deep data. Corresponds to type attribute deeptile.
  • CompressedScanLineBlock
    A Block of possibly compressed flat scan lines. Corresponds to type attribute scanlineimage.
  • CompressedTileBlock
    This Block is a tile of flat (non-deep) data. Corresponds to type attribute tiledimage.
  • TileCoordinates
    Indicates the position and resolution level of a TileBlock or DeepTileBlock.

Enums§

  • CompressedBlock
    The raw, possibly compressed pixel data of a file. Each layer in a file can have a different type. Also contains positioning information that locates this data block in the corresponding layer. Exists inside a Chunk.
