Hi OpenLayers users, I have a web application serving ocean forecasts which is very similar to this one:
http://ocean.dmi.dk/anim/index.uk.php Presently I am simply serving my maps as png files on a web page. This works fine but I would like to take advantage of the advanced features in OpenLayers. I have therefore started porting my application to OpenLayers (it is my first encounter with OpenLayers). It works fine. The only problem I have encountered is that every time I change Layer (for example by going one timestep forward in the forecast) the display of the image blinks (unlike the link above). This is quite annoying. Is the solution to this to use Tween to create a smooth transition between to Layers? I tried it but I haven't been able to understand how to do it. I hope someone can help me out. What I tried is simply: tween = new OpenLayers.Tween(OpenLayers.Easing.Expo.easeOut) tween.start(layer1, layer2, 30, {}) where layer1 and layer2 are the layers I want to make the transition between. In the class documentation it states that the first and second arguments to the start method should be: {Object} values to start/finish the animation with What are these values? Is it Layer objects or something else? I am also in doubt about whether I need to pass something in as the 4th argument. Hope somebody can help - Jesper _______________________________________________ Users mailing list [email protected] http://openlayers.org/mailman/listinfo/users
