如何在 GWT 中旋转 Google 地图标记?
如何在 GWT 中旋转 Google 地图自定义图像标记?我想根据方位添加和旋转单个图标。
目前,我将标记构建为普通标记覆盖,如下所示:
Icon icon = Icon.newInstance(imageUrl);
MarkerOptions markerOptions = MarkerOptions.newInstance(icon);
Marker marker = new Marker(point, markerOptions);
map.addOverlay(marker);
How do you rotate Google Maps custom image markers in GWT? I would like to add and rotate individual icons based on a bearing.
Currently, I construct the markers as a plain marker overlay, as follows:
Icon icon = Icon.newInstance(imageUrl);
MarkerOptions markerOptions = MarkerOptions.newInstance(icon);
Marker marker = new Marker(point, markerOptions);
map.addOverlay(marker);
