This message was previously posted to the user mailing list, but this list is
probably a more appropriate venue.
I had posted to the openlayers-users list in June asking about state and/or
plans to support WMS-T in OpenLayers. Since then I continued the work started
by Matt Priour to build an integrated control for WMS-T animations in
I have now reached a state advanced enough, yet far from complete(see know
issues below), about which I would like feedback. In particular, I am looking
for comments about the code I wrote. Did I do things the correctly? Does my
code comply with the OL way of doing things? Are there obvious bugs or
potential pitfalls? Also, do the visual components respect OL's look & feel?
In the long run, I would like to see this integrated into the main release of
OpenLayers. I built code on top of OL 2.13.1. I don't have any idea of the
effort required to port it to OL 3.x.
Besides adding a few PNG file to the img folder and adding 3 files
(lib/OpenLayers/TimeAgent.js, lib/OpenLayers/TimeAgent/WMS.js, examples/time-
animation.html), the only files that required modifications were
theme/default/style.css and lib/OpenLayers.js.
An example of the control can be viewed at :
http://collaboration.cmc.ec.gc.ca/cmc/air/OpenLayers/lib contains the entire
OL 2.13.1 code with the modifications I made.
==> Known issues :
- The previous frame button doesn't work
- The last frame button doesn't work
- No control to enable/disable looping
- Panel with playback buttons is ugly and wastes space at the bottom
I will continue work to fix theses issues. I also plan to make
corrections/modifications based on your comments and suggestions.
