It superseeds our previous tifffile plugin and aims to expose all the features of tifffile. The plugin treats individual TIFF series as ndimages. A series is a sequence of TIFF pages that, when combined describe a meaningful unit, e.g., a volumetric image (where each slice is stored on an individual page) or a multi-color staining picture (where each stain is stored on an individual page). Different TIFF flavors/variants use series in different ways and, as such, the resulting reading behavior may vary depending on the program used while creating a particular TIFF file.

Parameters ---------- request : iio.Request A request object that represents the users intent. It provides a standard interface for a plugin to access the various ImageResources. Check the docs for details. kwargs : Any Additional kwargs are forwarded to tifffile's constructor, i.e. to ``TiffFile`` for reading or ``TiffWriter`` for writing.

Parameters ---------- ndimage : ArrayLike The ndimage to encode and write to the ImageResource. is_batch : bool If True, the first dimension of the given ndimage is treated as a batch dimension and each element will create a new series. kwargs : Any Additional kwargs are forwarded to TiffWriter's ``write`` method. Returns ------- encoded_image : bytes If the ImageResource is ``""``, return the encoded bytes. Otherwise write returns None. Notes ----- Incremental writing is supported. Subsequent calls to ``write`` will create new series unless ``contiguous=True`` is used, in which case the call to write will append to the current series.

The metadata returned depends on the value of both ``index`` and ``page``. ``index`` selects a series and ``page`` allows selecting a single page from the selected series. If ``index=Ellipsis``, ``page`` is understood as a flat index, i.e., the selection ignores individual series inside the file. If ``index=Ellipsis`` and ``page=None`` then global (file-level) metadata is returned. Parameters ---------- index : int Select the series of which to extract metadata from. If Ellipsis, treat page as a flat index into the file's pages. page : int If not None, select the page of which to extract metadata from. If None, read series-level metadata or, if ``index=...`` global, file-level metadata. exclude_applied : bool For API compatibility. Currently ignored. Returns ------- metadata : dict A dictionary with information regarding the tiff flavor (file-level) or tiff tags (page-level).

The properties returned depend on the value of both ``index`` and ``page``. ``index`` selects a series and ``page`` allows selecting a single page from the selected series. If ``index=Ellipsis``, ``page`` is understood as a flat index, i.e., the selection ignores individual series inside the file. If ``index=Ellipsis`` and ``page=None`` then global (file-level) properties are returned. If ``index=Ellipsis`` and ``page=...``, file-level properties for the flattened index are returned. Parameters ---------- index : int If ``int``, select the ndimage (series) located at that index inside the file. If ``Ellipsis`` and ``page`` is ``int`` extract the properties of the page located at that (flat) index inside the file. If ``Ellipsis`` and ``page=None``, return the properties for the batch of all ndimages in the file. page : int If ``None`` return the properties of the full ndimage. If ``...`` return the properties of the flattened index. If ``int``, return the properties of the page at the selected index only.
