imageio.v3.immeta(uri, *, index=None, plugin=None, extension=None, exclude_applied=True, **kwargs)[source]#

Read format-specific metadata.

Opens the given URI and reads metadata for an ndimage from it. The contents of the returned metadata dictionary is specific to both the image format and plugin used to open the ImageResource. To learn about the exact behavior, check the documentation of the relevant plugin. Typically, immeta returns a dictionary specific to the image format, where keys match metadata field names and values are a field’s contents.

uri{str, pathlib.Path, bytes, file}

The resource to load the image from, e.g. a filename, pathlib.Path, http address or file object, see the docs for more info.

index{int, None}

If the ImageResource contains multiple ndimages, and index is an integer, select the index-th ndimage from among them and return its metadata. If index is an ellipsis (…), return global metadata. If index is None, let the plugin decide the default.

plugin{str, None}

The plugin to be used. If None (default), performs a search for a matching plugin.


If not None, treat the provided ImageResource as if it had the given extension. This affects the order in which backends are considered.


Additional keyword arguments will be passed to the plugin’s metadata method.


The ndimage located at the given URI.
