so yes, with a moments collected thought, I just added the standard svg header around that svg node and yes, it displays in a browser window standalone. I can now see that aside from the transform="scale(1,-1)" there are no other tricky coords going on.. So then I can see that indeed, many of the points, perhaps even 29 of them, are outside of the viewing area in some way.. So the question simply becomes why? pre-fetch for better browsing ?.. looks like the span of pts is roughly... double the dimensions ? or a buffer of 400-500 px worth ? perhaps this is documented behavior, I just havent read everything yet > insights, pointers welcome -Brian _______________________________________________ Users mailing list [email protected] http://openlayers.org/mailman/listinfo/users
