Export Jupyter Widget as picture

[ccarli]

Feature Request

A perspective-widget python method to save the widget as a picture (something like widget.to_picture(path.png))

Use-case:

In my organisation we use jupyter notebooks in jupyterlab environment to automate tasks and reports, often sending automated emails to colleagues and management with latest available data in table / charts.
I am using today persepective widgets in my python notebooks to explore and data because it's great and simple to use, but need to default back to matplotlib and styled dataframes when I want to send tables and charts in email.
I would be great if perspective offers a way to save the widgets as a picture for straightforward integration in emails.

possible duplicate to #1393, html export feature request.

Is this Issue still opened? @timkpaine
@texodus
I can see a possible duplicate #1393 which isn't exactly the same as the feature request above hence my question.

[timkpaine]

Some perspective plugins already support exports in the frontend via buttons, so this issue is really 2 fold:

• From python, access the PNG of a saved widget (this issue)
• From python, be able to export the widget into html (this is Export Jupyterlab notebook into HTML #1393)

Thanks for clarifying @timkpaine

Implemented in #2418.

Generating an actual PNG from python is not possible as the current iteration of the charting code is JavaScript (and heavily Chrome-centric). While we may eventually rewrite this, we no longer need to track support for the feature generally, so closing
