谷歌地图上的SVG标记没有出现

对我来说，符号有效，但它不在所需的位置。

使用锚属性，例如 anchor:new google.maps.Point(375,522)

在@geocodezip提到它看起来太大之后，我从另一个堆栈溢出帖子中找到了解决方案。

尽管我曾尝试将 Inkscape 中的图像大小调整为一个小的 24 像素图标，但这还不足以使图标出现。

找到了这篇文章，它是我问题的解决方案：使用 SVG 路径在折线上创建自定义符号

为了重申这里的解决方案，我在此 Web 应用程序中打开了 SVG 图像：http://svg-edit.googlecode.com/svn/branches/2.6/editor/svg-editor.html

在此应用程序中，我将其大小调整为正确的尺寸，然后单击"保存"。这样做给了我一个新的SVG坐标数据字符串，然后我在我的谷歌地图walkIcon对象中使用了它：
