Maybe this has been discussed before but I could not find one article that
explains it.
I am trying to figure out the proper way to read/write element's transform
values. I.e. X, Y, Scale,
Rotate, etc..
Below is a few things I have tried. Sometimes they work and sometimes they
don't. And I am not sure which way is correct.
Please point me in the right direction.
Thanks,
fireball.
Read
------
- X value:
((SVGOMGElement)elt).getTransform().getBaseVal().getItem(0).getMatrix().getE();
or
((SVGLocatable)elt).getScreenCTM().getE();
Write
------
- X value:
elt.setAttributeNS(null, "transform", "matrix(" + a + ",0,0," + d + "," + e
+ ",
" + f + ")");
or
((SVGLocatable)elt).getScreenCTM().setE(e);
- Rotation angle:
((SVGOMGElement)elt).getTransform().getBaseVal().getItem(0).setRotate(Float.valueOf(rotate),
Float.valueOf(0), Float.valueOf(0));
or
((SVGLocatable)elt).getScreenCTM().rotate(Float.valueOf(45));
In the above we are setting the rotate value but how do we get(read) it?
