All, Hi, new user. I'm using a vector layer for placing markers on the map, and I'm using the externalGraphic property to specify a marker of my own. How is that image anchored with respect to the lat/lon coordinates that it represents?
That is, if exactly one pixel in the external graphic corresponds to the point on the map, is it: a) The top left corner pixel b) The top right corner pixel c) The bottom left corner pixel d) The bottom right corner pixel e) The exact center pixel f) A pixel halfway along one edge Or g) something else entirely? I need to know so that I can figure out the correct offsets to use with my graphic. I tried to figure this out by using an external graphic for the marker which was a 1x1 pixel animated GIF blinking red/white/red/white and then defining another marker for the same coordinates with a translucent version of the regular image. But the 1x1 graphic refused to show up, even when I disabled the other marker so that it was on its own. Weird. Thanks!
