Remarks

Symbols describe how graphics and features look on a map. Different symbols are used with different geometry types. Marker symbols are used to display graphics and features that are based on point or multipoint geometries such as cities, a route destination, or fire hydrants. Subclasses of this class represent specific types of marker symbols such as SimpleMarkerSymbol, PictureMarkerSymbol, or TextSymbol.

You can specify the following two types of offsets:

• Offset the visible symbol from the symbol's point geometry.
• Offset a callout's leader line from the symbol's point geometry.

For each offset, you can specify an x-offset and a y-offset in device independent pixels (DIPs) using a Cartesian coordinate system. For example, if you specify a callout x-offset of -5.0, the callout's leader line will offset to the left along the x-axis by five points.

By default, the center of a is placed at the MapPoint location. If the image is a pushpin, for example, you may want the needle of the pushpin to end at the MapPoint location. In this situation, you need to offset the symbol to make the needle's end coincide with that MapPoint location.

You can control the rotation of the marker symbol using the Angle. However, you must also consider whether this rotation is relative to the map or screen (AngleAlignment).

Properties

Name	Description
Angle	Gets or sets the angle (in degrees) that the marker symbol is rotated by.
AngleAlignment	Gets or sets the indicates whether the marker symbol is rotated relative to the screen or map.
LeaderOffsetX	Gets or sets the callout leader's X offset relative to the marker symbol.
LeaderOffsetY	Gets or sets the callout leader's Y offset relative to the marker symbol.
OffsetX	Gets or sets the offset X of the marker symbol relative to the graphic or feature's point geometry.
OffsetY	Gets or sets the offset Y of the marker symbol relative to the graphic or feature's point geometry.
