In these styles, the icon scale refers to the ratio of the icon relative to original picture size; the icon path is the network access location of the image, such as http://maps.google.com/mapfiles/kml/pal3/icon19.png, the image shown as:; Users can also customize a picture placed in the % SuperMap iServer_HOME% \webapps\iserver directory and of any directory of % SuperMap iServer_HOME%\webapps\iserver\resources, for example, if users want to use an image named icon30.png, and can put this image in % SuperMap iServer_HOME% \ webapps \ iserver \ resources \ images directory, and then sets the label image address as http://iserver:8090/iserver/resources/images/icon30.png. The color used is hexadecimal, after editing, the text box will automatically display the color, such as ff0000 displayed red in Google Earth, 00ff00 shown as green, while ff00ff shown as magenta.

The default style is the default point, line, polygon display style: The label color is white, and the ratio is 1, the used image address is http://maps.google.com/mapfiles/kml/pal3/icon19.png; the line color is purple, and the line width is 4; the fill color within the polygon is green. In the default settings, opens the KML service published by SuperMap iServer 11i(2024) in Google Earth, and then the style will be displayed.
