InputStream to JSVGCanvas and retrieval in xml doc.
Hi,
I would like to know if it is possible to give an
inputstream (in svg format) to JSVGCanvas, perform
zoom, pan, rotate operations and retrieve the
transformed image in the form of a w3c xml document ?
how can this be achieved ?

Prajakta:
I am not sure if this can be achieved via JSVGCanvas or not (sounds like
it should happen at the GVT layer), but I would recommend the simpler
approach of using XSLT or an even simpler (sed?) mechanism to add the
transforms to the outermost <g> element in the SVG file.
Try adding 'transform="scale(0.5, 0.5)"', etc. to your <g> element by
hand:
<svg>
<g transform="translate(-100,-50) scale (0.5, 0.3) rotate(45)
translate (175, 50)">
...
</g>
</svg>
No need to parse the file ;-)
