A gradient is a smooth transition from one color to another, and the gradient backgrounds make your presentation very cool. This article will show you how to create a shape with gradient effects by using Spire.Presentation. With the help of Spire.Presentation, you can not only insert gradient shapes into the slides, but also insert solid shapes in PowerPoint in C# easily.
The following steps will give you clear information of how to fill a shape with gradient effects. We will use rectangle shape in this example.
Step 1: Create an instance of presentation.
Presentation ppt = new Presentation();
Step 2: Add a rectangle to the slide.
IAutoShape GradientShape = (IAutoShape)ppt.Slides[0].Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(200, 100, 287, 100));
Step 3: Set the Fill Type of the Shape to Gradient.
GradientShape.Fill.FillType = FillFormatType.Gradient;
Step 4: Set the start and end color for the gradient effects.
GradientShape.Fill.Gradient.GradientStops.Append(0, Color.Purple); GradientShape.Fill.Gradient.GradientStops.Append(1, Color.Red);
Step 5: Save and Launch to view the resulted PPTX file.
ppt.SaveToFile("CreateGradientShape.pptx", FileFormat.Pptx2010);
System.Diagnostics.Process.Start("CreateGradientShape.pptx");
Effective screenshot of the resulted gradient shape:

{
Presentation ppt = new Presentation();
IAutoShape GradientShape = (IAutoShape)ppt.Slides[0].Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(200, 100, 287, 100));
GradientShape.Fill.FillType = FillFormatType.Gradient;
GradientShape.Fill.Gradient.GradientStops.Append(0, Color.Purple);
GradientShape.Fill.Gradient.GradientStops.Append(1, Color.Red);
ppt.SaveToFile("CreateGradientShape.pptx", FileFormat.Pptx2010);
System.Diagnostics.Process.Start("CreateGradientShape.pptx");
}
}
}
