While this works for PostScript, it does not work for Quartz.

The NSFrameRect family of routines are odd ducks to begin with. In
some ways, they tend to to be more pixel oriented than your typical
drawing routines. For

Offsetting by 0.5 makes it draw such that the exact pixel is filled.
When a bezier path is more complicated it can become very ugly to add
0.5 to all coordinates.
To avoid this the NSBezierPath class offers the method -
transformUsingAffineTransform:
So you can create a
Hi,
I'm trying to draw a rounded rectangle with a 1 pixel-perfect wide
border. Although I made sure that the rect has integral values and its
height it an even number (so that height/2.0 is also even), the top
and bottom lines look blurry (screenshot:
It works!
Why such a behaviour?
Thanks,

Try adding these lines before creating the NSBezierPath:
cellFrame.origin.x += 0.5;
cellFrame.origin.y += 0.5;
Let me know if it works. It should.

Because strokes are drawn centred on the coordinate of the path, so a
1-pixel line extends 0.5 of a pixel above and below the coordinate.
Offsetting by 0.5 makes it draw such that the exact pixel is filled.
