xmlOverlayUseCanvas is a (dirty) global variable defined in kaXmlOverlay.js<br><br>After the directive <br><br><script type="text/javascript" src="XMLOverlay/kaXmlOverlay.js"></script><br><br>
this variable should be globally defined and initialized to "true".<br><br>The use of this variable is described in the documentation of kaXmlOverlay that is in the JavaScript file, and is mirrored and beautified in
<br><br><a href="http://ka-map.ominiverdi.org/wiki/index.php/Overlay_API_Reference">http://ka-map.ominiverdi.org/wiki/index.php/Overlay_API_Reference</a><br><br>If you can't find the xmlOverlayUseCanvas variable, probably you are using an old version of kaXmlOverlay. If this is the case, so my hint is not usefull for you.

In order to properly initialize kaXmlOverlay you should wait for the KAMAP_MAP_INITIALIZED event. So register an handler for that event <br><br>myKaMap.registerForEvent( KAMAP_MAP_INITIALIZED, null, mapInitializedHandler );
<br><br>and move the kaXmlOverlay init in the mapInitializedHandler() function.<br>(See the doc in the source).<br><br><br>For the bad icon rendering, if you are using the CVS version, the default behaviour is to render icons with <canvas> or VML, in order to support rotation.
<br><br>To render icons in the old traditional way set the variable<br><br> xmlOverlayUseCanvas = false;<br><br>before creating
the overlay.<br><br>If this helps, please let me know which browser you're using.<br><br> -Pg <br><br><div><span class="gmail_quote">2006/7/26, Alvin Clay <<a href="mailto:orionkamap@yahoo.com" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
