Examples of ae.java.awt.geom.AffineTransform.inverseTransform()

ae.java.awt.geom.AffineTransform.inverseTransform()

Inverse transforms the specified ptSrc and stores the result in ptDst. If ptDst is null, a new Point2D object is allocated and then the result of the transform is stored in this object. In either case, ptDst, which contains the transformed point, is returned for convenience. If ptSrc and ptDst are the same object, the input point is correctly overwritten with the transformed point. @param ptSrc the point to be inverse transformed @param ptDst the resulting transformed point @return ptDst, which contains the result of theinverse transform. @exception NoninvertibleTransformException if the matrix cannot beinverted. @since 1.2

        at.transform(loc, loc);
        pxResult.x = (int)loc.getX(); // but must not behave oddly around zero
        pxResult.y = (int)loc.getY();
        loc.setLocation(pxResult.x, pxResult.y);
        try {
            at.inverseTransform(loc, loc);
        }
        catch (NoninvertibleTransformException e) {
            throw new IllegalArgumentException("must be able to invert frc transform");
