自定义图标未显示在谷歌地图上

标签: javascript google-maps-api-3 push

我遇到的问题只是我无法加载自定义图标。标记本身会加载,但只有默认图标。如果我设置了图标,我可以加载自定义图标:在标记对象中手动输入,如下所示:

        var marker = new google.maps.Marker({
            position: places[i],
            map: map,
            icon: sizeIcons['one']
        })

然后他们都加载得很好。但我想设置大小,所以我添加了下面的代码,该代码在我的KML生成器中有效但由于某种原因无法生成我的自定义图标。有什么想法吗?我没有发布所有代码,但$ content [1]的值是50到450之间的数字。

的index.html

$sizeFloat = (int) $content[1];
                    if($sizeFloat  < 50){
                        ?>
                        <script type="text/javascript">

答案 0 :(得分:1)

我不确定,但可能是由于您缺少原点:new google.maps.Point(0,0)您当前传入null的位置。通常,当您将图片网址传递为图标时,地图API会为您创建MarkerImage对象,并默认此信息并确定身高和数据。宽度自动。我猜你希望你的图标与中心点对齐,因为你的锚点位于24,24。但是你可能需要定义一个原点,即使它是0,0

可以使用精灵这些因为谷歌让你能够使用单个图像和该图像中的多个“正方形”作为不同的点。所以假设你有100 x 100像素的图像。在此图像中,您可以将4个50x50图标排列在网格中。因此,一个MarkerImage可以是0,050,50,该行中的下一个是0,50100,50。等等第二行。
