Re: [Google Maps API v3] Re: GMapsV3 - lots of MarkerImages slow down everything
That's right - the map pans much faster because the browser has already composited the marker icons into the canvas element.

[Google Maps API v3] Re: GMapsV3 - lots of MarkerImages slow down everything
I've replaced scaled size with null in my MarkerImage constructor and am now seeing canvas elements (using Firebug) instead of img elements. Marker click events all working fine too - touch wood.

[Google Maps API v3] Re: GMapsV3 - lots of MarkerImages slow down everything
I agree. I tend to use the full MarkerImage constructor and have been specifying a scaled size equal to the original icon size. This means i've unknowingingly been disabling any canvas optimisations for my maps! Defintely worth a mention in the documentation i say. Can Ben confirm that passing null as the scaled size property won't cause un-optimalised markers? I have a marker manager script that needs to get each icon's size and anchor point so my code needs to icon size and anchor in the MarkerImage constructor. Passing null as scaled size but passing icon size and icon anchor point will give me canvas optimised markers will it? Thanks a lot. Martin.

[Google Maps API v3] Re: GMapsV3 - lots of MarkerImages slow down everything
Hi. Are you implying that canvas markers will only be used if a MarkerImage is constructed with a string URL only? And that using the 'full' MarkerImage constructor with all properties set will cause non-optimised markers? Or could the scaled size be passed as null to acheive optimised canvas markers? Martin.
