Re: How to draw a simply dot in cairo?

[Allen <allenfans gmail com>]

 think he means he used something like this:
 
    cairo_move_to(cr,x,y);
    cairo_arc (cr, x, y, r, 2*M_PI);
    cairo_fill (cr);
 
Instead of drawing a cricle with cairo_arc first then cairo_filling it, does cairo provide any alternatives for this task?

Hi,

I know how to draw line, arc(circle) in cairo. however, I cannot find the efficient way to draw a simple round dot. I tried arc(), it works, however, it is very slow. I need draw thousands of the small dot with different radius. arc() is a little bit slow to do that.

I also tried draw a rectangle with round cap, round join and 0 width and height. It works and seems faster than arc(). But I may in the wrong track.

Could anyone point me out, how to draw a lot of dot with different radius efficiently? Thanks.
