Aihe: [Geoserver-devel] Dropping the WMS animator, superceded* by WPS Download
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.
Maybe not many know that WMS has an “animator”, which can build animated gifs:
https://docs.geoserver.org/latest/en/user/tutorials/animreflector.html
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
