ThinkGeo.MapSuite.MvcEdition.Overlay

<!– Class –> Serves as the base class that defines the properties and methods shared by all types of overlays.

Remarks

The <strong>Overlay</strong> has as similar concept to the Layer. Different types of overlays stack over each other to form a map. An overlay object is responsible for getting the configuration information from the user and serializing it to a JSON string to control the client Javascript library, which creates the appropriate client layer.

Usually, an overlay represents an image with a transparent background that is laid upon other overlay, such as a <strong>LayerOverlay</strong> or <strong>WmsOverlay</strong>. While the <strong>MarkerOverlay</strong> will not be rendered as an image, it actually represents a <strong>div</strong> that holds several marker images at the client side.

There are basically two kinds of overlays: base overlays and non-base overlays.

A base overlay has its <strong>IsBaseOverlay</strong> property set to true. It is displayed as the background image of the map. In an <strong>OverlaySwitcher</strong>, there is a radio button beside its name. There can be only one base overlay displayed at a time. You can click the radio button to switch the base overlay that is displayed.

A non-base overlay has a false <strong>IsBaseOverlay</strong> property. These overlays can overlap the base overlay and/or each other. They are displayed in the <strong>OverlaySwitcher</strong> with a check box beside their name. You can click the check box to show or hide a specific overlay.
