SVG File Not well drawn

[qxdo]

I run demo code in the test case, just modified my svg file, like this,
`

str := []string{"00dbdcf748734ed890fbf39ca76ce266",
"1ade369b862d44118c126ff8f80bbd1b",
"1bedfd263a1f4ca58c660806e03e80e7",
"1d7d7deed0ae484a8e893950ad700582",
"1e6c8acc04134b5a91cf1ecc1d43c433",
"1ed618bb2816400bbc29e40fffae8114",
"1fbd523827844e4ebea89657ea16c3de",
"2be84432e3ea4e01a919be01ec79fff5",
"2c2766e105bf4081b7f46d50a840d017",
"4c8536828410457ebd2996e3b2437863",
"4d1078d7548045d7921329e9ea91fe0c",
"4f0f35b1b5454a4482cecb693564c98b",
"4fe9018d54ec43da999f6712e2b4afc9",

"5ec8889735b04398a7e17a54761f0c31"}
for _, s := range str {
iconPath := "gg_demo/icons2/" + s + ".svg"

	icon, errSvg := oksvg.ReadIcon(iconPath, oksvg.WarnErrorMode)
	if errSvg != nil {
		fmt.Println(errSvg)
		return
	}
	w, h := int(icon.ViewBox.W), int(icon.ViewBox.H)
	img := image.NewRGBA(image.Rect(0, 0, w, h))
	tb := img.Bounds()
	tb.Max.X /= 2
	scannerGV := rasterx.NewScannerGV(w, h, img, img.Bounds())
	raster := rasterx.NewDasher(w, h, scannerGV)
	icon.Draw(raster, 1.0)
	if img != nil {
		p := strings.Split(iconPath, "/")
		err := SaveToPngFile(fmt.Sprintf("gg_demo/targets/%s.png", p[len(p)-1]), img)
		if err != nil {
			fmt.Println(err)
			return
		}
	}
}

`

and the final result like this:
