Conversion for AffineTransform?

["Bishop, Michael W. CONTR J9C880" <Mi...@je.jfcom.mil>]

I'm looking for something similar to SVGColor.toSVG() or
SVGShape.toSVG().  I see there's an SVGOMMatrix that takes an
AffineTransform as a constructor argument, but I don't see a way to
create the 'transform="..."' from it.  Does one exist?  Similarly, is
there one to go from a 'transform="..."' back to some object?  I'm doing
it with string parsing and it's kinda ugly.

    It's trivial to construct if you are willing to use the 'matrix()'
form.  You can also have a 'translate(tx, ty) matrix(sx, shy, shx, sy, 0, 
0)'
so the transform is pulled out (sx = scaleX, shx = shearX, etc).
If you don't want to use matrix then it depends on you knowing the
form of your affine.

    You can use the parser classes from Batik:
        batik.parser.TransformListParser
      batik.parser.AWTTransformProducer
