LineFillFormat.SetGradientFill(GradientType, IEnumerable<GradientStop>) Method

Applies a complex gradient to a line or a shape’s border.

Namespace: DevExpress.XtraRichEdit.API.Native

Assembly: DevExpress.RichEdit.v22.2.Core.dll

NuGet Package: DevExpress.RichEdit.Core


void SetGradientFill(
    GradientType gradientType,
    IEnumerable<GradientStop> gradientStops


Name Type Description
gradientType GradientType

An enumeration member that specifies the gradient type.

gradientStops IEnumerable<GradientStop>

A list of objects that contain information about gradient stops.


The example below shows how to apply a gradient of three colors to a rectangle’s outline.


// Create a rectangle.
Shape rectangle = document.Shapes.InsertShape(document.Range.Start, ShapeGeometryPreset.Rectangle, new RectangleF(300, 200, 500, 300));
// Format the rectangle's outline.
ShapeLine border = rectangle.Line;
// Apply a linear gradient of three colors to the outline.
GradientStop stop1 = new GradientStop(0f, Color.FromArgb(0x1B, 0x98, 0xE0));
GradientStop stop2 = new GradientStop(0.5f, Color.FromArgb(0xF3, 0xFF, 0xBD));
GradientStop stop3 = new GradientStop(1f, Color.FromArgb(0xFF, 0x16, 0x54));
border.Fill.SetGradientFill(GradientType.Linear, new GradientStop[] { stop1, stop2, stop3 });
border.Fill.GradientFill.Angle = 30;
// Set the line width.
border.Thickness = 6;

Use the LineFillFormat.GradientFill property to adjust existing gradient settings or add more gradient stops.
