Question

What Library Can I Use to Manipulate SVG Files?

Answer 1

A:

One of the Qt libraries have similar functionality and you can probably do most of the transformation operations with it:

Answer 2

+1 A:

I don't know of a library which directly fulfils the requirements you've listed, but I think these things would not be difficult to script simply using the SVG DOM.

For the first task, it sounds like the easiest thing would simply be to group the two shapes.


var shape1 = document.getElementById("shape1");
var shape2 = document.getElementById("shape2");
var newG = document.createElementNS(svgNs,"g");
shape1.parentNode.removeChild(shape1);
shape2.parentNode.removeChild(shape2);
newG.appendChild(shape1);
newG.appendChild(shape2);

For the second task, you can just get the bounding box of a shape and find the centre point of that.


var bbox = shape1.getBBox();
var centrePoint = {x:bbox.x + bbox.width/2, y:bbox.y + bbox.height/2};

For the third task, you can copy a shape, and then apply a scale transformation to it.


var shape1Clone = shape1.cloneNode(true);
shape1Clone.setAttributeNS(null,"transform","scale(.75)")

In order to automate this so that you can run it on a remote machine, you can use the Apache Batik library, and do the scripting with Rhino. Take a look at this for an example how to do this:
