Re: dynamic image manipulation

There may be some Javascript trick to do this, although I can't really picture it. If you want this really in real-time you need a Java applet. If you can deal with pseudo-realtime, meaning a frame reload every time you need to update the frame with the graph in it, then PHP can do it. -Rasmus On Sat, 14 Oct 2000, Kdtc wrote: > Kdtc wrote: > > > I have a similar file as button.php, but it creates an empty 800x500 > > image. > > > > Now, I have two frames (top_frame, and bot_frame) on my main window. > > The topframe's source is a PHP file and ditto with the bottom frame. > > > > I'm using javascript(side question: can javascript also > > dynamically manipulate/draw graphics?) to create a series of random > > values > > and then I want them to be plotted (in real time) to the empty image; > > thus, > > creating a graph.
