Hi all!
In my project I have to refresh a mapserver layer every 20/40 seconds.
I do this with:
refreshinterval = window.setInterval("refreshmap()", 20000);
function refreshmap(){
...
mslayer.redraw(true);
...
}
That is OK. But every refresh action, there is a flick effect.
When the refresh event is fired, OL turn off the old-layer and wait to
the images for new one. And the server calculation for the maplayer is
0.2 sec.
Any idea?
I do not know how to detect when the browser finished to render the
new images. (may be the download finished time is also useful).
Greets,
Ernesto
