Module chunk

Read and write already compressed pixel data blocks. Does not include the process of compression and decompression.

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. The byte data is in little-endian format, as these bytes will be written into the file directly.

CompressedDeepScanLineBlock

This Block consists of one or more deep scan lines. Corresponds to type attribute deepscanline. The byte data is in little-endian format, as these bytes will be written into the file directly.

CompressedDeepTileBlock

This Block is a tile of deep data. Corresponds to type attribute deeptile. The byte data is in little-endian format, as these bytes will be written into the file directly.

CompressedScanLineBlock

A Block of possibly compressed flat scan lines. Corresponds to type attribute scanlineimage. The byte data is in little-endian format, as these bytes will be written into the file directly.

CompressedTileBlock

This Block is a tile of flat (non-deep) data. Corresponds to type attribute tiledimage. The byte data is in little-endian format, as these bytes will be written into the file directly.

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. The byte data is in little-endian format, as these bytes will be written into the file directly.
