  • y_pos (int) – Y position in pixels from top; default is center of current view

  • angle (float) – Angle of text orientation; default is 0.0 (horizontal)

  • opacity (int) – Opacity of fill color. Must be an integer between 0 and 100; default is 100

  • brightness (int) – Image brightness. Must be an integer between -100 and 100; default is 0.

  • border_color (str) – hexadecimal color; default is #000000 (black)

  • border_opacity (int) – Integer between 0 and 100; default is 100

  • height (int) – Height of bounding shape; default is based on text height

  • width (int) –

  • name (str) – Name of annotation object; default is “Text”

  • canvas (str) – Canvas to display annotation, i.e., foreground (default) or background

  • z_order (int) – Arrangement order specified by number (larger values are in front of smaller values); default is 0

  • network (SUID or str or None) – Name or SUID of the network. Default is the “current” network active in Cytoscape.

  • base_url (str) – Ignore unless you need to specify a custom domain, port or version to connect to the CyREST API. Default is http://localhost:1234 and the latest version of the CyREST API supported by this version of py4cytoscape.
