notebook_export_show_image(filename='image', type='PNG', resolution=None, units=None, height=None, width=None, zoom=None, sandbox_name=None, network=None, base_url='http://127.0.0.1:1234/v1', *, overwrite_file=True)[source]

Show network view in notebook output.

Export a network view to an image file, then upload the file to the notebook file system and display the image.

Parameters

  • filename (str) – Full path or path relative to current working directory, in addition to the name of the file. File is used to save image of network view so it can be transferred to the notebook file system and displayed. Extension is automatically added based on the type argument.

  • type (str) – Type of image to export, e.g., PNG (default), JPEG, PDF, SVG, PS (PostScript).

  • resolution (int) – The resolution of the exported image, in DPI. Valid only for bitmap formats, when the selected width and height ‘units’ is inches. The possible values are: 72 (default), 100, 150, 300, 600.

  • units (str) – The possible values are: pixels (default), inches.

  • height (float) – The height of the exported image. Valid only for bitmap formats, such as PNG and JPEG.

  • width (float) – The width of the exported image. Valid only for bitmap formats, such as PNG and JPEG.

  • zoom (float) – The zoom value to proportionally scale the image. The default value is 100.0. Valid only for bitmap formats, such as PNG and JPEG

  • sandbox_name (str) – Name of sandbox containing file. None means “the current sandbox”.

  • network (str or SUID or None) – Name or SUID of the network or view. Default is the “current” network active in Cytoscape. If a network view SUID is provided, then it is validated and used.

  • base_url (str) – Ignore unless you need to specify a custom domain, port or version to connect to the CyREST API. Default is http://127.0.0.1:1234 and the latest version of the CyREST API supported by this version of py4cytoscape.

  • overwrite_file (bool) – False allows Cytoscape show a message box before overwriting the file if the file already exists; True allows Cytoscape to overwrite it without asking

Returns

iPython.display.Image class instance

Return type

object

Raises

  • CyError – if network doesn’t exist or the file cannot be written

  • requests.exceptions.RequestException – if can’t connect to Cytoscape or Cytoscape returns an error
