thanks Holger what you suggested makes sense, but my question was wrong in the first place. What I meant was when the user scroll down or up, how do I still find the center. Not pan. With a bit more research, I found the answer, ie., scrollTop property. It gives the top most pixel of the current screen.
I am trying to write a process flow chart editor, something like Visio, but using .NET C#, web browser control, Adobe SVG viewer. Once agains, many thanks for your response. regards Ben chong QMatrix --- In [email protected], Holger Will <[EMAIL PROTECTED]> wrote: > hi Ben > > > can anyone tell me how to get the coordinates > > of the center of the screen no matter how you pan the svg > > document, ie., if I pan to the bottom right corner I want > > the coordinates at the center of the screen/window. > > you would do something like : > -determin the center of your initial screen. > - get currentTranslate and currentScale > -apply these transformations to the point > > > I need to know the coordinates so when I, say, add an object, > > it will appear on the screen for the user to see (and not > > at an arbitrary X,Y which might be out of view. > > couldnt you let the user click where he wants the object to be inserted ? > > hth > Holger ----- To unsubscribe send a message to: [EMAIL PROTECTED] -or- visit http://groups.yahoo.com/group/svg-developers and click "edit my membership" ---- Yahoo!
