interaction with a group of severals JSVGCanvas
Hello,
I’m looking for solutions and advices about Batik.
Actually, I’m loading a SVG file in a JSVGCanvas and it is rendered fine.
OS : Windows XP Pro SP2 using eclipse V3.1 with Batik API
But the thing is that I’m trying to use several SVG file and group them into the same object in order to Pan, rotate, Zoom them all together.
For example:
- I load a SVG map in a JSVGCanvas
- This JSVGCanvas is added to a JPanel
- I need to set several positions on this map with a cross image (svg, jpg ...)
- I want them to move, rotate, and zoom all together, not only the SVG map. Actually, the cross has to follow all the actions performed on the map.
I don’t know which method to use to perform this.
Here are some methods I thought about :
- Create a JSVGCanvas for each cross image and add it to the JSVGCanvas map ?
- Use only 1 Canvas for the map and add my crosses to it ?
I look forward to hearing from you.
Cheers.

If you set the canvas to be ALWAYS_DYNAMIC then you can modify the
document's DOM directly (modifications must be done in the UpdateManager's
runnable queue thread - read FAQ).
When you add/modify the image element's the canvas will only
re-render the modified portion of the display.
Good luck!

ok nice, but if I add my jpeg files directly into the SVG file, I think there will be a decrease of perfs, because in order to have a good display I will have to refresh regularly the map and it takes "many times" to load a svg...

Yes. You can add ‘image’ elements that refer to the JPEG file for every
cross that you want displayed on your map.

Hi, thanks
Wo do you mean by : "Certainly it would be easier to use the one JSVGCanvas, and add your
crosses into the SVG document"?
Do I have to fill the SVG file (XML file) with the JPEG Cross? If true, how can I do that.
Any advices?
Regards.

Certainly it would be easier to use the one JSVGCanvas, and add your
crosses into the SVG document. Then when the map is panned or zoomed,
the crosses will follow naturally.
