(this may nad may not relate to this thread) I like to share with you my experiment with SVG to increase its speed. You can try that yoursself. It will make your SVG "FAST". (I have server side C code to convert SVG to Javascript Array and load it as XMLHTTP but its not the point I like make). I will try illustrate what I did by using Javascript code: I walk thru the dom to convert SVG to Javascript Array. such as: SVG= new Array(); SVG["First_G"]=new Array(); SVG["First_G"]["First_path"]=new Array(); SVG["First_G"]["First_path"]["d"]=""M0,0 C12, 13, 14.."; SVG["First_G"]["First_path"]["fill-opacity"]="0.5". SVG["First_G"]["First_path"]["stroke-color"]="255,255,255" SVG["First_G"]["Second_path"]=new Array(); So on . . . You also need a piece of code (using join(). . . ) to convert it back to SVG code Pay more attention on ["style"] thing. then submit it to the player. (depend on browser) You will see it realy fast when you updating the SVG's element/ attribute specially on large SVG file. Hope this helps.
