"""
A set of objects representing each file extension recognized by ImageIO. If an
extension is not listed here it is still supported, as long as there exists a
supporting backend.

class FileExtension:
    """File Extension Metadata

    This class holds information about a image file format associated with a
    given extension. This information is used to track plugins that are known to
    be able to handle a particular format. It also contains additional
    information about a format, which is used when creating the supported format
    docs.

    Plugins known to be able to handle this format are ordered by a ``priority``
    list. This list is used to determine the ideal plugin to use when choosing a
    plugin based on file extension.

    Parameters
    ----------
    extension : str
        The name of the extension including the initial dot, e.g. ".png".
    priority : List
        A list of plugin names (entries in config.known_plugins) that can handle
        this format. The position of a plugin expresses a preference, e.g.
        ["plugin1", "plugin2"] indicates that, if available, plugin1 should be
        preferred over plugin2 when handling a request related to this format.
    name : str
        The full name of the format.
    description : str
        A description of the format.
    external_link : str
        A link to further information about the format. Typically, the format's
        specification.

    Examples

class FileExtension:
    """File Extension Metadata

    This class holds information about a image file format associated with a
    given extension. This information is used to track plugins that are known to
    be able to handle a particular format. It also contains additional
    information about a format, which is used when creating the supported format
    docs.

    Plugins known to be able to handle this format are ordered by a ``priority``
    list. This list is used to determine the ideal plugin to use when choosing a
    plugin based on file extension.

    Parameters
    ----------
    extension : str
        The name of the extension including the initial dot, e.g. ".png".
    priority : List
        A list of plugin names (entries in config.known_plugins) that can handle
        this format. The position of a plugin expresses a preference, e.g.
        ["plugin1", "plugin2"] indicates that, if available, plugin1 should be
        preferred over plugin2 when handling a request related to this format.
    name : str
        The full name of the format.
    description : str
        A description of the format.
    external_link : str
        A link to further information about the format. Typically, the format's
        specification.

    Examples

A set of objects representing each file extension recognized by ImageIO. If an extension is not listed here it is still supported, as long as there exists a supporting backend. File Extension Metadata      This class holds information about a image file format associated with a     given extension. This information is used to track plugins that are known to     be able to handle a particular format. It also contains additional     information about a format, which is used when creating the supported format     docs.      Plugins known to be able to handle this format are ordered by a ``priority``     list. This list is used to determine the ideal plugin to use when choosing a     plugin based on file extension.      Parameters     ----------     extension : str         The name of the extension including the initial dot, e.g. ".png".     priority : List         A list of plugin names (entries in config.known_plugins) that can handle         this format. The position of a plugin expresses a preference, e.g.         ["plugin1", "plugin2"] indicates that, if available, plugin1 should be         preferred over plugin2 when handling a request related to this format.     name : str         The full name of the format.     description : str         A description of the format.     external_link : str         A link to further information about the format. Typically, the format's         specification.
