public class GradientPattern
extends Object
implements com.esri.arcgis.interop.RemoteObjRef, IFillPattern, IGraphicAttributes, IGraphicAttributes2, IDrawingOutline, IPersist, IPersistStream, ISupportErrorInfo, IDocumentVersionSupportGEN, Externalizable

A gradient fill pattern object.

Description

GradientPattern is used to draw a BasicFillSymbol using a color ramp.

Remarks

A GradientPattern is used to draw BasicFillSymbol with a gradient fill pattern.

Use IFillPattern interface to create a new GradientPattern and IGraphicAttributes interface to assign attribute values to the fill pattern.

This object can be controlled using the following GraphicAttributes:

• Color 1 - esriAttributeTypeColor
• Color 2 - esriAttributeTypeColor
• Style - esriAttributeTypeEnum
• Intervals - esriAttributeTypeEnum
• Percentage - esriAttributeInteger
• Algorithm - esriAttributeDouble
• Angle - esriAttributeDouble

The following example shows how to assign values to the attributes of a GradientPattern using IGraphicAttributes interface.
