Re: Drawing in a JSVGCanvas

It is not working. What's not working, your method isn't called, you don't see your drawing, it doesn't compile? The LoadSVGCanvas that I wrote is doing nothing at the movement of the mouse. Why are you loading the canvas on mouse move? Basically I replicated what I had implemented for a regular class that extends JPanel. My first guess would be you are drawing before the SVG content is drawn rather than after. Am I using the wrong class? Is there any other JSVG* class that should be used for the purpose of loading an image and also drawing on top of it? No I think you are using the correct class, but I suspect that you are not overriding the methods properly. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Drawing in a JSVGCanvas
In fact the problem came from the SVG file itself. the viewBox attribute didn't correspond to other information provided in the file. So all coordinates calculations was wrong (in my sense). I've found the problem by trying many changes in the SVG file. My problem is that I don't really understand all informations in that file. I should probably read more about SVG. Is there some interesting books or links you should recommend ? Thanks anyway.
