My Qt project is to add the jitter effect (handshaking) in a SVG drawing. An example of Jitter effect is shown in the link.

So far my application can load an SVG image and display it using Graphic View. Next I need to change the shape of the curves in of the SVG drawing randomly to create the handshaking effect. My problem now is how I could find out those points. May I know is there a function in Qt that I can use to extract the points (coordinates) of SVG drawing?

Sorry if you couldn't understand my question clearly. Please feel free to ask me again.
