How to disable JSVGCanvas automatic resizing?

[William Huang]

The JSVGCanvas by default automatically adapts its size to the size of the document. I want to disable this behavior. That is, if the SVG size can't fit into the browser window, it will just display a part that can be accommodated in this window and show scrollbar. I also don't want this displayed image being clipped to window size. Which program should I modify?   And for the scrolling to work, I need to know information about the actual SVG size. For example, when I load an SVG file with width="10.278in" and height="9.167in" using image tag, specify size 800,600 for the image node, then I get 800 when I call getWidth of this image node. How can I deal with this problem? Thanks a lot. Best regards, William
