the s1 value has to be updated dynamically all the time the map is resized. This has to be achieved by a Javascript function that gets the new value based on the input parameters from the map (map height for maximum zoom out in map coordinates) and height of the current map in pixels.
An easy solution should be to write the initial max Y-extent ($y_dgeo) to a JS variable via PHP and then use this one to calculate the new s1 value based on the updated map pixel-height. The Javascript function would be similar to the 'returnmaxScale' in PHP. In most cases you will just set the map resolution to 96 (the most reasonable value for it since most users are using Windows that assumes a screen resolution of 96). And if assumes that you have metric coordinates. armin Gambin Dejan wrote: > Hi Armin, > > I have changed the returnMaxScale function in order to use my > $_SESSION["initext"] value instead of map->extent values.
