Example

The following example replaces an existing point layer's symbol with a newly created RasterMarkerSymbol.
Visual BasicCopy Code
' Create a new raster marker symbol and set its properties

Dim rasterMarkerSymb As New RasterMarkerSymbol()

rasterMarkerSymb.Image = "C:\Temp\citysymbol.gif"

' Url property isn't used by image services--only needed if using Web ADF TOC control

rasterMarkerSymb.Url = "http://myserver/temp/citysymbol.gif"

rasterMarkerSymb.AllowLabelOverlap = False

rasterMarkerSymb.Antialiasing = True

rasterMarkerSymb.Height = 16

rasterMarkerSymb.Width = 16

rasterMarkerSymb.Hotspot = New System.Drawing.Point(2, 2)

rasterMarkerSymb.ShadowColor = Drawing.Color.DarkBlue

rasterMarkerSymb.Transparency = 30



' Retrieve an existing point layer's renderer

Dim layer As FeatureLayer = mapView.Layers.FindByName("Cities")

Dim grpRend As GroupRenderer = layer.Renderer



' Create a new simple renderer to contain the symbol, and replace the existing feature renderer

Dim simpleRend As New SimpleRenderer(rasterMarkerSymb)

grpRend.Renderers.RemoveAt(0)

grpRend.Renderers.Add(simpleRend)

Remarks

This symbol allows drawing of raster images as symbols on the map. Images should be kept relatively small. The image is drawn on the map by the server, so that the raster image does not need to be available to the client (browser).

Typically this class used to symbolize point features, but may also be used to symbolize line or polygon features.

May be used either to symbolize a FeatureLayer within its renderer, or to symbolize a GeometryElement in an acetate layer.

For ArcMap Server image services, valid only for acetate layers. ArcMap Server ignores several of the properties of this class. For details, see the topic for RASTERMARKERSYMBOL in the ArcIMS Help, at ArcXML Guide - Symbol elements - RASTERMARKERSYMBOL. The ArcIMS Help is also available online at ESRI).
