How to cut a shape in two ?

I'm not aware of a specific knife tool, at the moment you need to create shapes manually, however there are plenty of free vector image editors out there that you can import from.

Thank you for correction Knife

yes I am trying to import two png in snigle frame it seem messed up. but single png is ok.

have a look at this following link, that's why I thought there it maybe a function like cutting image in two by product itself.

Just very occasionally I have had a situation where the gui did not give me exactly what I got at run time. Try moving the images, then click on to view in browser to check the relative position in the finished version.
