Problem about the JSVGScrollCanvas and JSVGViewport

[征宇 王 <tr...@yahoo.com.cn>]

Hi,I have used the JSVGScrollCanvas and JSVGViewport created by
 Zachary DelProposto.After my SVGDom is load,I can see ScrollBar at bottom and left.But the scrollbar can not scroll at all.Only after I used "shift+mouse" to "pan" the SVG,the scrollBars worked well.Could anyone tell me how can I get scrollbars work correctly just when the DOM is loaded.Thx

Hi 征宇 王,

   The default behavior (in fact the one prescribed by the
SVG spec) is that when the content has a viewBox the viewBox
is fitted to the visible area.  Since the extent of the
scrollbars is limited to the viewBox there is nothing for the
scrollbars to scroll, everything is visible.

   If you don't want this behavior you can change the
'calculateViewingTransform' method of the JSVGCanvas so
it doesn't fit the content to the viewable space.

   The scrollbar should then be visible.

   Also you may be aware that Batik now includes an updated
version of Zachary's original JSVGScrollCanvas (I'm not sure
what the JSVGViewport is).
