To improve performance, plugins are only loaded as needed. As a result, there can be multiple states for a given plugin: available: Defined in an *ini file located in `skimage.io._plugins`. See also `skimage.io.available_plugins`. partial definition: Specified in an *ini file, but not defined in the corresponding plugin module. This will raise an error when loaded. available but not on this system: Defined in `skimage.io._plugins`, but a dependent library (e.g. Qt, PIL) is not available on your system. This will raise an error when loaded. loaded: The real availability is determined when it's explicitly loaded, either because it's one of the default plugins, or because it's loaded explicitly by the user. iÿÿÿÿNt3(t ConfigParser(tglobi(timread_collection_wrappert use_plugint call_plugint plugin_infot plugin_ordert reset_pluginstfind_available_pluginstavailable_pluginstpilt matplotlibtqttalltimshowtimshow_collectioncCs4igd6gd6gd6gd6gd6gd6adS(sNClear the plugin state to the default, i.e., where no plugins are loaded timreadtimsaveRtimread_collectionRt _app_showN(t plugin_store(((s8lib/python2.7/site-packages/skimage/io/manage_plugins.pyt_clear_plugins6s  cCssdddddg}x|D]}t|tdƒqWd„tjƒDƒ}x|D]}t|t|ƒqTWdS(NRRRRRRcss!|]}|dkr|VqdS(RN((t.0tp((s8lib/python2.7/site-packages/skimage/io/manage_plugins.pys Ms(t _set_plugintpreferred_pluginstkeys(tio_typestp_typet plugin_types((s8lib/python2.7/site-packages/skimage/io/manage_plugins.pyt_load_preferred_pluginsFs    cCsYxR|D]J}|tkrqnyt|d|ƒPWqtttfk rPqXqWdS(Ntkind(R Rt ImportErrort RuntimeErrortOSError(t plugin_typet plugin_listtplugin((s8lib/python2.7/site-packages/skimage/io/manage_plugins.pyRRs  cCstƒtƒdS(N(RR(((s8lib/python2.7/site-packages/skimage/io/manage_plugins.pyR]scCsftƒ}|j|ƒ|jƒd}i}x-|j|ƒD]}|j||ƒ||Return plugin name and meta-data dict from plugin config file.i(Rtreadtsectionstoptionstget(tfilenametparsertnamet meta_datatopt((s8lib/python2.7/site-packages/skimage/io/manage_plugins.pyt_parse_config_filebs  c Cs3tjjtƒ}ttjj|ddƒƒ}xü|D]ô}t|ƒ\}}|t|>> from skimage import io >>> io.use_plugin('matplotlib', 'imread') To see a list of available plugins run ``io.available_plugins``.
