ESRI.ArcGIS.ADF.IMS.Display.Symbol Namespace : GradientFillSymbol Class

Visual Basic (Declaration)

Visual Basic (Usage)

C#

FillSymbol used to fill polygons with a gradual gradient based on two colors.

Syntax

Visual Basic (Declaration)
<SerializableAttribute()> Public Class GradientFillSymbol Inherits FillSymbol

Visual Basic (Usage)	Copy Code
`Dim instance As GradientFillSymbol`

C#
[SerializableAttribute()] public class GradientFillSymbol : FillSymbol

Example

This example replaces the existing symbol for a countries layer with a GradientFillSymbol, which shades each country with a gradient vertically with a transition between two colors.

FeatureLayer layer = mapView.Layers.FindByName("Countries"); 

SimpleRenderer renderer = layer.Renderer; 

  

// Replace the renderer's symbol with the one we created 

renderer.Symbol = simpleFillSymb;

Remarks

GradientFillSymbol fills each polygon to which the renderer applies with a gradual gradient, from the StartColor to the FinishColor. The Type property determines where the StartColor starts and in which direction the change progresses.

GradientFillSymbol does not outline polygon features. If outlines are desired, it is possible to use a GroupRenderer to combine this symbol with a SimpleFillSymbol (or a line symbol).

For ArcMap Server image services, valid only for acetate layers. ArcMap Server ignores several of the properties of this class.
