WPF - Simple path not producing expected result

Question

I am trying to replicate a very simple image using a path in WPF, but somehow the path does not produce the results I expect.

This is the Image I want

This is the Path I use

<Path Stroke="Black" StrokeThickness="1" Data="M0,2 L2,4 L6,0"
   SnapsToDevicePixels="True" RenderOptions.EdgeMode="Aliased" />

This gets returned

How is this possible?

Do you use any transformations? This might be possible due to SnapsToDevicePixels set to True — netaholic, Sep 29 '15 at 13:44
Is it a question of units? As here: http://stackoverflow.com/questions/14192399/why-all-positions-sizes-are-in-double-format? — PScr, Sep 29 '15 at 14:09

I've added a green line through the coordinates you are drawing, which makes it obvious why you get that output.

You should draw the lower point at the center of a pixel, e.g. like this:

<Path Data="M0,2 L2.5,4.5 L7,0" .../>

I was completely thinking in pixels instead of pixels as the result of my line. Thanks for this perfect answer Clemens, the picture makes it soo much better! – Bastiaan Sep 30 '15 at 14:45
