Firebug on, and no flickering.<br><br><div class="gmail_quote">On Wed, Nov 18, 2009 at 11:58 AM, Marc Jansen <span dir="ltr"><<a href="mailto:jansen@terrestris.de">jansen@terrestris.de</a>></span> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
Hey Pedro,<br>
<br>
Do you have the firebug plugin? Is it enabled for the link with the demo? Would you be so kind to test that as well... because right now I cannot reproduce the flickering on my machine! (How could that be?)<br>
<br>
This is *really* annoying, I can't get my head around the problem.<br>
<br>
Thanks and regards,<br>
Marc<br>

For the record, I am currently using FF 3.5.5, Gecko/20091102 on Windows and I don't see any flickering in the link you posted.<br>

Hi list,<br>
<br>
when the URL of an imagelayer is changed via the APIMethod setUrl, the<br>
image is flickering regardless of the browser cache or the transition<br>
effect. This behaviour can be seen e.g. here:<br>
<br>
<a href="http://www.webmapcenter.de/wetterradar/animation.html" target="_blank">http://www.webmapcenter.de/wetterradar/animation.html</a><br>
<br>
In that demo the URL of the imagelayer is changed every 500 ms and the<br>
flickering should be easy to spot (at least if you wait for roughly 20<br>
seconds). Firebugs Net-tab shows that the images are being requested<br>
over and over.<br>
<br>
The flickering is only noticeable in Firefox (3.5 Win and Linux);<br>
Opera<br>
10 and IE 8 work like a charm (they cache the varying images). The<br>
changing of the src of a pure <img> with JavaScript does not show the<br>
flickering (as can be seen in the above link, too). I don't have<br>
results<br>
for other browsers.<br>
<br>
Can anybody help me identify the root of this flickering? I am unsure<br>
whether this Firefox bugreport is maybe relevant to this issue:<br>
<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=492052" target="_blank">https://bugzilla.mozilla.org/show_bug.cgi?id=492052</a>. I doubt that<br>
it is<br>
related to apache settings (Caching- or Expires-Headers) as the<br>
pure JS<br>
solution isn't flickering at all.<br>
<br>
Any help or advice on this issue would be great!<br>
<br>
Regards,<br>
Marc<br>
<br>
BTW.: If someone shows me a better alternative to build an<br>
animation of<br>
different Imagelayers, I would be happy as well :-)<br>
