Hi,
if all your shapes are included in a g element, you can use the getBBox method
on this node to get the dimensions.
In your example :
document.getElementById('G2').getBBox()

Objet: [svg-developers] showing full svg content whithout calculating extents
Hello
I need help for finding extents of an svg drawing. Please take a look at this
example:
<svg id="SVG1" width="5cm" height="5cm" viewBox="0 -100 200 200">
<g id="G2">
<line x1="0" y1="0" x2="100" y2="100" stroke="blue"/>
<line x1="0" y1="0" x2="0" y2="100" stroke="blue"/>
<line x1="0" y1="0" x2="100" y2="0" stroke="blue"/>
<line x1="0" y1="0" x2="100" y2="-100" stroke="blue"/>
</g>
</svg>
For this sample it was easy to understand that viewBox="0 -100 200 200" will
fit the whole drawing. But in my real world application this will not be so
easy to calculate this. And without this viewbox or with incorrect
calculations, at least a part of drawing will not be shown which is not
desirable.
I want to show the whole drawing in svg without getting involved in calculating
the extents. Something like zoom extents in aoutocad. could you please help?
Thanks
