### Question:
SvgInkscapeUtils { public static String transformToAttribute(Matrix3f m) { return SvgTransformUtils.serializeTransform(m); }  static String getLabel(Element element); static boolean isLayer(Element element); static String getGroupMode(Element element); static Matrix3f getTransform(Element element); static Matrix3f getTransform(Element element, Matrix3f m); static Matrix3f parseTransformAttribute(String transformAttribute, Matrix3f m); static String transformToAttribute(Matrix3f m); static boolean isFlipped(Matrix3f matrix); static final String INKSCAPE; static final String SODIPODI; static final String XLINK; }### Answer:
@Test public void testMatrixToSvgAttribute() { Matrix3f matrix = new Matrix3f(); matrix.setIdentity(); matrix.m00 = 1f; matrix.m10 = 2f; matrix.m01 = 3f; matrix.m11 = 4f; matrix.m02 = 5f; matrix.m12 = 6f; String transformToAttribute = SvgInkscapeUtils.transformToAttribute(matrix); assertThat(transformToAttribute , IsEqual.equalTo("matrix(1.0,2.0,3.0,4.0,5.0,6.0)")); }
