Color

GradientStop.Color property

Gets or sets a value representing the color of the gradient stop.

public Color Color { get; set; }

Examples

Shows how to add gradient stops to the gradient fill.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

Shape shape = builder.InsertShape(ShapeType.Rectangle, 80, 80);
shape.Fill.TwoColorGradient(Color.Green, Color.Red, GradientStyle.Horizontal, GradientVariant.Variant2);

// Get gradient stops collection.
GradientStopCollection gradientStops = shape.Fill.GradientStops;

// Change first gradient stop.
gradientStops[0].Color = Color.Aqua;
gradientStops[0].Position = 0.1;
gradientStops[0].Transparency = 0.25;

// Add new gradient stop to the end of collection.
GradientStop gradientStop = new GradientStop(Color.Brown, 0.5);
gradientStops.Add(gradientStop);

// Remove gradient stop at index 1.
gradientStops.RemoveAt(1);
// And insert new gradient stop at the same index 1.
gradientStops.Insert(1, new GradientStop(Color.Chocolate, 0.75, 0.3));

// Remove last gradient stop in the collection.
gradientStop = gradientStops[2];
gradientStops.Remove(gradientStop);

Assert.AreEqual(2, gradientStops.Count);

Assert.AreEqual(Color.FromArgb(255, 0, 255, 255), gradientStops[0].BaseColor);
Assert.AreEqual(Color.Aqua.ToArgb(), gradientStops[0].Color.ToArgb());
Assert.AreEqual(0.1d, gradientStops[0].Position, 0.01d);
Assert.AreEqual(0.25d, gradientStops[0].Transparency, 0.01d);

Assert.AreEqual(Color.Chocolate.ToArgb(), gradientStops[1].Color.ToArgb());
Assert.AreEqual(0.75d, gradientStops[1].Position, 0.01d);
Assert.AreEqual(0.3d, gradientStops[1].Transparency, 0.01d);

// Use the compliance option to define the shape using DML
// if you want to get "GradientStops" property after the document saves.
OoxmlSaveOptions saveOptions = new OoxmlSaveOptions { Compliance = OoxmlCompliance.Iso29500_2008_Strict };

doc.Save(ArtifactsDir + "Shape.GradientStops.docx", saveOptions);
