Introduction

Aspose.Slides for .NET is a powerful library that facilitates working with PowerPoint presentations in the .NET environment. If you want to enhance your presentations by formatting rectangle shapes dynamically, this tutorial is for you. In this step-by-step guide, we will walk you through the process of formatting a rectangle shape in a presentation using Aspose.Slides for .NET.

Prerequisites

Before we dive into the tutorial, make sure you have the following prerequisites in place:

• A development environment with Aspose.Slides for .NET installed.
• Basic knowledge of C# programming language.
• Familiarity with creating and manipulating PowerPoint presentations. Now, let’s get started with the tutorial!

Import Namespaces

In your C# code, you need to import the necessary namespaces to use Aspose.Slides functionalities. Add the following namespaces at the beginning of your code:

using System.IO;
using Aspose.Slides;
using System.Drawing;

Step 1: Set up Your Document Directory

Begin by setting up the directory where you want to save your PowerPoint presentation file. Replace "Your Document Directory" with the actual path to your directory.

string dataDir = "Your Document Directory";
bool IsExists = System.IO.Directory.Exists(dataDir);
if (!IsExists)
    System.IO.Directory.CreateDirectory(dataDir);

Step 2: Create a Presentation Object

Instantiate the Presentation class to represent the PPTX file. This will be the foundation for your PowerPoint presentation.

using (Presentation pres = new Presentation())
{
    // Your code goes here
}

Step 3: Get the First Slide

Access the first slide in your presentation, as it will be the canvas where you add and format the rectangle shape.

ISlide sld = pres.Slides[0];

Step 4: Add a Rectangle Shape

Use the Shapes property of the slide to add an auto shape of rectangle type. Specify the position and dimensions of the rectangle.

IShape shp = sld.Shapes.AddAutoShape(ShapeType.Rectangle, 50, 150, 150, 50);

Step 5: Apply Formatting to the Rectangle Shape

Now, let’s apply some formatting to the rectangle shape. Set the fill color, line color, and width of the shape to customize its appearance.

shp.FillFormat.FillType = FillType.Solid;
shp.FillFormat.SolidFillColor.Color = Color.Chocolate;
shp.LineFormat.FillFormat.FillType = FillType.Solid;
shp.LineFormat.FillFormat.SolidFillColor.Color = Color.Black;
shp.LineFormat.Width = 5;

Step 6: Save the Presentation

Write the modified presentation to disk using the Save method, specifying the file format as PPTX.

pres.Save(dataDir + "RectShp2_out.pptx", SaveFormat.Pptx);

Congratulations! You’ve successfully formatted a rectangle shape in a presentation using Aspose.Slides for .NET.
