The horizontal padding is caused by the text containers lineFragmentPadding. Concerning the vertical offset, you can find the following in the docs of -drawGlyphsForGlyphRange:atPoint: "This method expects the coordinate system of the view to be flipped." I'm not sure how to make your context flipped, the following works but is deprecated: NSGraphicsContext.setCurrentContext(NSGraphicsContext(CGContext: binContext.CGContext, flipped: true)) But then you also need to change the current transformation matrix to make the end result upright: let t = NSAffineTransform() t.translateXBy(0, yBy: kSquareSize) t.scaleXBy(1, yBy: -1) t.concat() I assume that probably it would be easier to use Core Text for drawing to a Bitmap Context.
