kml - 将特定样式应用于 KML 中 MultiGeometry 中的线条

Question

您好，我有一个多几何图形，当您将鼠标传递给线条时，样式如何像翻转一样，我的问题是多几何图形中的不同线串可能具有不同的颜色？

在下一个示例中，当您选择样式时，我有地标 Durham Tees Valley，但我希望两条线具有不同的颜色。

谢谢

Answer 1

不，请参阅 KML 常见问题解答，他们解决了您的 question :

Can I assign different colors/styles to different geometries in a MultiGeometry element?

The MultiGeometry element groups geometries together in the same Placemark element. This allows the geometries to share the same styling and to appear as one item in a list such as the My Places pane in Google Earth.

Styles are set at the Placemark level, either using a styleUrl element or a Style element. Therefore, individual geometries in that Placemark cannot have different styles.

另请参阅我发现有用的解决方法:

A frequently used workaround is to create a separate Placemark for each geometry, allowing each one to have a different style. To prevent a proliferation of items in a list, place them in a Folder that has a ListStyle with a listItemType with checkHideChildren. In Google Earth, for instance, this places all the Placemarks in the same folder element in My Places, and prevents the user from opening it up to display a large number of elements.
