# Tango File

Images defined by file and directory tango attributes, e.g. `Pilatus` without Hidra

The Tango File image source frame contains the following fields:

- File Attr: selects the tango attributes of the last image file,
  e.g. `p09/pilatus/haso228k/LastImageTaken`
  The possible file attributes can be preselected in the configuration dialog.
- Dir Attr: selects the tango attributes of the last image file directory,
  e.g. `p09/pilatus/haso228k/LastImagePath`
  The possible file directory attributes can be preselected in the configuration dialog.
- Status: shows the connection status. It also displays a port of ZMQ security stream if it is enabled.
- Start/Stop button to launch or interrupt image querying

Tango File attribute contains a string with the file name in a raw format or `file:/` or `h5file:/` scheme.
