How can I make a limit on the the pan range?

[hwoarangzk]

I mean, my svg is in a div container, and I don't want the svg pan too right or too left which can cause the user see the empty container. Can I make a limit to my svg in the container? Allow it only to move to the right side by 50px e.g.?
Thanks.

BTW, is there any scale-like property that I could set this value directly to controll the scale of the svg?

And could I set a time period to zoom out or zoom in the svg? I mean, just like animate in jQuery that I can set number of milliseconds for the animation to run?
Thank you :)

No right now it is not implemented, but there is issue #37 which is similar. You can see a solution for what you are asking in that issue thread.

There is zoomScaleSensitivity option that allows controlling mouse zoom sensitivity.

No, there is no such option.

What you can do is to disable zoom (using zoomEnabled option) and create scroll listener. And when user scrolls call API zoom method with desired parameters (you'll have to compute zoom scale and zoom point by yourself).

I didn't mean the zoomScaleSensitivity. What I wanna say is that is there a scale method that I could change the scale of my svg directly? Like:

$('#svg1').scale(2);

Thank you~

Yes, there are currently 4 methods for zooming: zoom, zoomBy, zoomAtPoint, zoomAtPointBy.
You can find examples in Readme

Yes, zoom is what I'm looking for, thank you!
