Hi:
I use this function to revert the transform to the initial state of the svg
tree
canvas.resetRenderingTransform();
what i like to do is to be able to keep only the rotation transform, and
revert the "zoom" and "translate" back to the initial state.
I beleive this could be done by getting the rotation angle before this
method is called, and applying it after the call as follows:
//get rotation angle "theta" here
canvas.resetRenderingTransform();
AffineTransform at = new AffineTransform();
at.rotate(theta, canvas.getWidth()/2,canvas.getHeight()/2);
at.concatenate(canvas.getRenderingTransform());//i am not usre if this
is necessary in this case but i put it anyway!
canvas.setRenderingTransform(at);
I don't seem to be able to calculate the theta right.
can someone please tell me how to get theta?
and if you see something wrong in what i am doing above, please point it
out.
many thanks
hilz
