html5 - Fill color for an arc drawed by canvas -


i trying fill color arc. but, don't want use ctx.linewidth that.

you need define continuous path able fill single color if don't want use line-width.

using 2 arcs means need "reverse" 1 of them end-points connect correctly without crossing. can using counter-close wise flag @ end set true , swap start , end angles:

ctx.arc(w/2, h, h-40, 2*math.pi, math.pi, true);  // ccw, swapped angles ctx.arc(w/2, h, h, math.pi, 2*math.pi); ctx.fill();                                       // can filled
