In order to solve a scaling problem, I have the following question:
graphics.drawLine(x1,y1,x2,y2); draws a line between 2 points.
Does it draw this Lines "on Top" of those points or is it drawn below them?
See my Image for clarification:
The upper example shows how an Oval is drawn with graphics.fillOval(x,y,w,h); where the black point is the x and y coordinate and the red circle is the actual oval...
Is it the same using graphics.drawLine() when using a new BasicStroke(3.5f, BasicStroke.CAP_ROUND, BasicStroke.JOIN_ROUND) like in the lower example?
Or is the line actually drawn centered to the coordinates?
Any help is appreciated.

3I have no idea. But why don't you just test it and see? – JB Nizet Jun 22 '16 at 16:16

@JBNizet how could I test this? – RoiEX Jun 22 '16 at 16:17

To better understand the problem, you'll need to draw a grid to represent pixels, and then fill them in to show how the geometric primitives are rendered. – Jun 22 '16 at 16:17

1Draw a 1x1 rectangle to mark the point. – Jun 22 '16 at 16:18

For drawLine(), the beginning of the arc portion will be at x location, so your picture is wrong. The rounded cap will protrude to the left of the left dot, and to the right of the right dot.
