This is what I wanted to tell but I had not time for it. Thanks for your report, this problem realy makes users screaming
Sorry, that code is what I wanted to show
Okey, I changed example code, look here please. The problem is the same: you can not zoom to the edges.
I created this example and if you will try to zoom to the top or bottom line – zoom functiom would not work.
Hello, is this topic alive? There is an example of zoom-enabled option. If you will try to zoom till the left edge of canvas – you would not get any result
