Note that AffineTransform transformations are concatenated “in the most commonly useful way”, which may be regarded as last in, first-out order. The effect can be seen in this example. Given the sequence below, the resulting Shape is first rotated, then scaled and finally translated. at.translate(SIZE/2, SIZE/2); at.scale(60, 60); at.rotate(Math.PI/4); return at.createTransformedShape(…);
