Re: changing the dimensions of the root svg element

[David Gellman]

Yes, Thomas, I did try that already (I should have mentioned that in my 
original message). And I've tried assigning a new viewBox to the root 
element, too. These have some of the desired effect, but when I rasterize 
the file using batik-rasterizer the resulting image retains the pixel 
dimensions of the original svg element statement.

I'd like to start with a canvas that's too large, then dynamically render 
content with scripted elements, and then "crop" the result (also in the 
script) so that the final, rasterized file is only the size of the 
dynamically-rendered elements.

Thanks, though, for the suggestion. I think it's the right idea in theory, 
but that in practice it won't control the final result the way I need.

Is there a way to change the height and width of the root svg element 
using ecmascript?

For example, let's say that I start with width="300" in the svg root 
element. Then I create a text node using ecmascript, append it to the 
root, and determine it's width with getComputedTextLength(). Is there a 
way for me to change the width of the root based on the width of the text 
(that is, to crop the document)?
    Have you tried 'setAttribute("width","100")' on the SVG element?

    This doesn't cause the document 'window' to resize but it should
cause the document to be clipped at the new width.
