Downloading current panel view as pdf

Panel
1

I am using panel on bokeh, and I want to download the current view in the panel as pdf, is it possible?

2

It is currently not possible, bokeh supports exporting individual plots as svgs but that wouldn’t cover the whole view and each plot is exported individually. There might be some solution by using a headless chromedriver to PDF print the page.

I’ve previously experimented with the options listed in the bokeh docs (e.g. crowbar) but never made that work. Please keep us updated @dewshrs!

Is there any update about this ?

Nope I don’t think so. @Marc has been working on a PR to make screenshots but I don’t know how advanced or even how likely this is to be merged. Feel free to open a feature request on Panel’s issue tracker if this is a feature that you would really like Panel to have!

From what I’ve been able to google search, exporting to PDF is a general problem to solve across web applications and its not easy. I believe its very difficult to get right.

I’ve been wanting to look into this as well, but haven’t gotten around to it yet.
I’m thinking there might be a possibility using the pn.save() to HTML, then converting the HTML to PDF?
I don’t know whether this will work with every object though, and I don’t know if there are good python libraries to generate a pdf from an html file.
