RFE: Export full graph at readable scale

[jshaughn]

The Kiali project had an RFE submitted for graph export at a readable scale. This means the user wants to be able to export a full layout at a scale that allows for labels to be readable, etc. In short, like a screenshot if the screen were big enough to render the entire topology at that scale. I don't know if this is feasible; my experience is only to be able to export the html elements that are currently visible on-screen.

I tried to adapt the solution used by NetObserv in this PFT Slack thread, but was not able to get it to work past what was on-screen (although it works nicely for that ability).

@jeff-phillips-18 Do you know how difficult this would be to implement? Could we do something like export to PDF?

[jeff-phillips-18]

@dlabaj I have not looked into this nor do I have any experience with HTML to PDF. If you can convert HTML elements that are off screen to PDF then you could determine the bounds of the graph, create a div that is large enough to show the entire graph and then convert that.

The slack thread mentioned is no longer available.

@jshaughn Do you have information on what you tried? Looks like the the slack thread is no longer available. Is this something you still need?

@dlabaj I don't recall the details, but in short I failed to find a way to capture the off-screen elements. We'd still like a way to capture a large topology, in readable scale, in a static format. I think in the Slack thread some other folks were also looking for a solution. If there were a way, I'd still be a little concerned of the size, as when anything is unbounded it tends to make bad things happen...
