Java - drawing a scaled up shape with line thickness of 1

Question

When you use Graphics2D.scale(); and draw a shape, the outline thickness is also scaled.

Is there a way to draw it without the line thickness being scaled? Perhaps there's another efficient way to scale it other than using the above function?

This question is similar. It looks like you have to mess around with a Stroke object to set the right line width.

You're going to have to save your drawing as a list of line vectors, and scale and render the drawing at various sizes to maintain the line thickness you want.

I've just found a solution to my own question. I've no idea how efficient it is but it works as intended:

Area area = new Area(myShape); //myShape is the shape I want to scale
AffineTransform at = new AffineTransform();
at.scale(2,2);
area = area.createTransformedArea(at);
graphics2d.draw(area); //graphics2d is the Graphics2D instance to do the drawing

Perhaps someone could enlighten me as to whether or not this is a good approach to take?
