This is mutually exclusive with specifying a non-zero `ifd`. + + * :json:schema:`~driver/tiff.tiff.ifd_stacking.dimensions` (Required): An array of unique string labels for the dimensions represented by the IFD sequence (e.g., `["z"]`, `["time", "channel"]`).

Defaults internally to `c`. This label must not conflict with labels in `ifd_stacking.dimensions`. + +**Rules:** + +* All IFDs involved in stacking must have uniform properties (Width, Height, DataType, Compression, etc.). +* The driver determines the final TensorStore dimension order based on the conceptual structure (Stacked dims..., Y, X, Sample dim) unless overridden by `schema.domain.labels`. + +Compression +----------- + +.. json:schema:: driver/tiff/Compression + +The driver automatically detects and decodes the compression method specified in the TIFF file's `Compression` tag. The following compression types are currently supported for decoding: + +.. json:schema:: driver/tiff/Compression/raw +.. json:schema:: driver/tiff/Compression/zlib +.. json:schema:: driver/tiff/Compression/zstd + +*(Support for other compression types like LZW or PackBits may be added in the future).* + +Mapping to TensorStore Schema +----------------------------- + +The TensorStore schema is derived from the TIFF tags and the interpretation options specified. + +Data Type +~~~~~~~~~ + +TensorStore infers the :json:schema:`~Schema.dtype` from the TIFF `BitsPerSample` and `SampleFormat` tags. Supported mappings include: + +* Unsigned Integers (`SampleFormat=1`): `uint8`, `uint16`, `uint32`, `uint64` +* Signed Integers (`SampleFormat=2`): `int8`, `int16`, `int32`, `int64` +* Floating Point (`SampleFormat=3`): `float32`, `float64` + +Mixed data types across samples (channels) are generally not supported. The driver handles byte order conversion (TIFF Little Endian or Big Endian) automatically based on the file header. + +Domain +~~~~~~ + +The :json:schema:`~Schema.domain` is determined as follows: + +* **Shape:** + * The base shape comes from `ImageLength` (Y) and `ImageWidth` (X). + * An additional dimension is added if `SamplesPerPixel` > 1. + * Dimensions from `ifd_stacking.dimensions` are added. + * The **default dimension order** is conceptually: `(stacked_dims..., 'y', 'x', sample_dim)`. For example, `("z", "y", "x")` or `("t", "c", "y", "x", "rgb")`. The actual final order can be permuted using `schema.domain.labels`. +* **Labels:** + * Default conceptual labels are `y`, `x`, the labels from `ifd_stacking.dimensions`, and the `sample_dimension_label` (or default `c`) if SamplesPerPixel > 1. + * These defaults become the final labels unless overridden by `schema.domain.labels`. +* **Origin:** The domain origin (:json:schema:`~IndexDomain.inclusive_min`) is always zero for all dimensions. +* **Resizing:** The domain is **fixed** and cannot be resized. + +Chunk Layout +~~~~~~~~~~~~ + +The :json:schema:`~Schema.chunk_layout` is derived from the TIFF tiling or strip information: + +* **Grid Shape:** Determined by `TileWidth`/`TileLength` or `ImageWidth`/`RowsPerStrip`, potentially including a size of 1 for stacked dimensions or the sample dimension (if planar). +* **Grid Origin:** Always zero for all dimensions. +* **Inner Order:** Defaults to C order relative to the final TensorStore dimension order (soft constraint). Can be overridden by `schema.chunk_layout.inner_order`. + +Codec +~~~~~ + +The :json:schema:`~Schema.codec` indicates the use of the TIFF driver and specifies the detected :json:schema:`~driver/tiff.codec.compression`. + +.. json:schema:: driver/tiff/Codec + +Fill Value +~~~~~~~~~~ + +TIFF files do not store a fill value. Reads of missing chunks (unlikely in valid TIFFs) will be filled with zero if :json:schema:`~DriverSpec.fill_missing_data_reads` is true (default). + +Dimension Units +~~~~~~~~~~~~~~~ + +Standard TIFF does not reliably store dimension units.
