Quartz 2D -Drawing a point

Question

I know that drawing a point by using drawing a line method in Quartz 2D is

CGContextMoveToPoint(context,x,y-0.5f);
CGContextAddLineToPoint(context,x,y+0.5f);

Is there any other possible way to draw a point using Quartz? I meant, some direct way of doing so?

What do you mean by "point"? A pixel? A rectangle of one by one point dimension? The presented code draws a diagonal line, not a point. — Nikolai Ruhe, Sep 27 '12 at 20:13
@NikolaiRuhe oops added wrong code.Sorry,edited.I am mentioning about a pixel — Lithu T.V, Sep 27 '12 at 20:17

if you want it to look like a circular point try this:

CGContextStrokeEllipseInRect(context, CGRectMake(x, y, 4, 4));

it will draw for you you a an ellipse inside a rectangle (above case is apparently a square). i prefer you to choose a square as it will look like a real circle and not oval one. however, this circle will be empty from the inside, you can fill it by a stroke. (but it looks cool like a donut!) :)
