Hi all,
as you know, the WPS download module is now a supported extension. The module provides
a good asynchronous animation building facility, which can be called in a asynchronous way and
generates MP4 movies.
It does not compare very well to the WPS download:
Can only do synchronous requests
It’s memory bound
Normally limited to URL size (I guess one could do a form POST though, haven’t tried)
Can only build animated GIFs (hence, relatively low compression)
Can only work with local GeoServer layers (WPS download can do on the fly cascade as well)
To be fair, it has one advantage over the WPS download, in that it can animate over any WMS
request parameter, like changing the bbox, or a view param, while WPS download only over time.
I don’t think anyone is seriously using it (did you know it was there in the first place?), and given
its runtime limits and memory consumption, I’d suggest to just drop it. Only on the dev branch,
and we can include a warning in the 2.19.0 release announcement for eventual users to switch
to the WPS download.
Opinions??
Cheers
Andrea
*: well, almost superceded!

Funny thing, i just discovered this endpoint again just now and found out that it does not work for “env” variables as advertised.
I tried various combinations of aparams=env and avalues=parameter:value1,parameter:value2 etc but none seems to be working.
I started to debug the code to find the issue, but it may be more future proof to checkout that download WPS.
I am not yet sure how good the old animate endpoint integrated into WMS clients, as it tends to be somewhat “GetMap” like.
So i guess it could be used in e.g. openlayers to request and draw those animated gifs on the map.
I assume that this is getting more complicated with a WPS, but that should no real blocker…

It was meant for a single time download, don’t think it was used in combination with an OpenLayers client.

Well if you need anything but time to drive the animation then the WPS won’t support it (yet).
At the same time, the animator has been sitting there without dedicated maintenance for a lot of time.
In this thread, I’m providing the work to remote it from the codebase. If you want to keep it instead, it would likely have to
be turned into a community module. Is it something you’d be interested in doing?

Yeah, realized that in the meanwhile, but after looking at the code i
think its absolutely possible to extend the WPS plugin to handle any
parameter, not only time for the animation.
I also figured out that there is no easy way of rendering animated gifs
since openlayers is using the canvas renderer and abandoned the dom
renderer.
Using mp4 movies in openlayers is possible, but codewise not implemented
at all. So it was just wishful thinking from my side, sorry for confusion.

I think the WPS superseeds the old endpoint and you dont need to keep
it. I hope i will get some time to work on the download WPS to extend it.
