r := sty.Radius + (sty.Radius-sty.Radius*sinπover6)/2
var p vg.Path
p.Move(pt.X, pt.Y+r)
p.Line(pt.X-r*cosπover6, pt.Y-r*sinπover6)
p.Line(pt.X+r*cosπover6, pt.Y-r*sinπover6)
p.Close()
da.Fill(p)
}示例2: FillPolygon
// FillPolygon fills a polygon with the given color.
func (da *DrawArea) FillPolygon(clr color.Color, pts []Point) {
if len(pts) == 0 {
return
}
da.SetColor(clr)
var p vg.Path
