bonjour pierre, the outermost svg tag in ASV has the properies innerWidth and innerHeight (you may call them with onload="myFunc(this,innerWidth,innerHeight);"). those values give you the extent of the canvas in px in whatever the plugin gets loaded.
on the other hand you have your initial viewBox width and height. those give you your drawing size in drawing units. with the pixels from above you get a scale (-figure). when the user zooms around, you can track this with the onzoom-event in the outermost svg tag. onlaod the value always is 1. as long as you do not touch the viewBox (re-inits onzoom with 1), onzoom always gives you a correct value of the actual zoom level. andr� -- ___________________________________________________________________ andre m. winter, <http://www.vectoreal.com/> SVG consulting and development <http://www.carto.net/> online cartography focusing on SVG <http://www.carto.at/> print and online touristic map solutions Bru, Pierre wrote: >AFAIK, there is no provision for level of detail (LOD) in SVG.
