Inserting charts to your PPT document is an easy and eye catching way to display important information. Spire.Presentation includes many different types of data charts including column charts, cylinder charts, cone charts, pyramid charts, clustered charts, line charts, pie charts, bar charts, area charts, scatter charts, stock charts, surface charts, contour charts, doughnut charts, bubble charts and radar charts.
Spire.Presentation for .NET, a reliable .NET PPT component, enables you to generate, read, edit, convert even print your PPT documents without installing Microsoft PowerPoint on your machine. Using Spire.Presentation for .NET, you also can insert charts in your PPT document with C#. Please see the target PPT document with chart as below picture:
The steps of method are:
Step 1: Create the PPT document.
Presentation presentation = new Presentation();
Step 2: Insert chart, set title and style of the chart.
RectangleF rect = new RectangleF(presentation.SlideSize.Size.Width / 2 - 200, 100, 400, 400); IChart chart = presentation.Slides[0].Shapes.AppendChart(Spire.Presentation.Charts.ChartType.Cylinder3DClustered, rect); chart.ChartTitle.TextProperties.Text = "Report"; chart.ChartTitle.TextProperties.IsCentered = true; chart.ChartTitle.Height = 30; chart.HasTitle = true;
Step 3: Prepare data for the chart. Load a simple DataTable from XML file via LoadData() method.
DataTable dataTable = LoadData();
private DataTable LoadData()
{
DataSet ds = new DataSet();
ds.ReadXmlSchema("data-schema.xml");
ds.ReadXml("data.xml");
return ds.Tables[0];
}
Step 4: Attach the data to chart. We can use chart.ChartData[rowIndex, columnIndex] to get/set the value of the specified cell in the data table of chart. Using the property chart.ChartData[rowIndex, columnIndex].Text to get/set the text value. Using the property chart.ChartData[rowIndex, columnIndex].Value to get/set numeric value. In this article we define a method InitChartData to attach the Data of the chart.
private void InitChartData(IChart chart, DataTable dataTable)
{
for (int c = 0; c < dataTable.Columns.Count; c++)
{
chart.ChartData[0, c].Text = dataTable.Columns[c].Caption;
}
for (int r = 0; r < dataTable.Rows.Count; r++)
{
object[] data = dataTable.Rows[r].ItemArray;
for (int c = 0; c < data.Length; c++)
{
chart.ChartData[r + 1, c].Value = data[c];
}
}
}
Step 5: Set the Series label and Category label.
chart.Series.SeriesLabel = chart.ChartData["B1", "D1"]; chart.Categories.CategoryLabels = chart.ChartData["A2", "A7"];
Step 6: Assign data to each Series and set each Series' fill color.
chart.Series[0].Values = chart.ChartData["B2", "B7"]; chart.Series[0].Fill.FillType = FillFormatType.Solid; chart.Series[0].Fill.SolidColor.KnownColor = KnownColors.Brown; chart.Series[1].Values = chart.ChartData["C2", "C7"]; chart.Series[1].Fill.FillType = FillFormatType.Solid; chart.Series[1].Fill.SolidColor.KnownColor = KnownColors.Green; chart.Series[2].Values = chart.ChartData["D2", "D7"]; chart.Series[2].Fill.FillType = FillFormatType.Solid; chart.Series[2].Fill.SolidColor.KnownColor = KnownColors.Orange;
Step 7: Set the 3D rotation.
chart.RotationThreeD.XDegree = 10; chart.RotationThreeD.YDegree = 10;
Step 8: Save the document.
presentation.SaveToFile("chart.pptx", FileFormat.Pptx2010);

Set a Background for a Slide Master in PowerPoint in C# and VB.NET
If you don’t wish to set backgrounds for slides one by one, you can set a background for the slide master, then all slides using the same slide master will be applied with the background automatically. The following steps show how to set a solid background color for a slide master:
- Initialize an instance of the Presentation class.
- Load a PowerPoint presentation using Presentation.LoadFromFile() method.
- Get a specific slide master using Presentation.Masters[int index] property.
- Access the background of the slide using ISlide.SlideBackground property.
- Set the type of the slide's background as a custom type using SlideBackground.Type property.
- Set the fill mode of the slide’s background as a solid fill using SlideBackground.Fill.FillType property.
- Set a color for the slide’s background using SlideBackground.Fill.SolidColor.Color property.
- Save the result presentation using Presentation.SaveToFile() method.
- C#
- VB.NET
using Spire.Presentation;
using Spire.Presentation.Drawing;
using System.Drawing;
namespace AddBackgroundToSlideMaster
{
internal class Program
{
static void Main(string[] args)
{
//Initialize an instance of the Presentation class
Presentation ppt = new Presentation();
//Load a PowerPoint presentation
ppt.LoadFromFile("Sample.pptx");
//Get the first slide master
IMasterSlide slide = ppt.Masters[0];
//Access the background of the slide
SlideBackground background = slide.SlideBackground;

Incorporating images into a PowerPoint presentation is crucial for captivating your audience and reinforcing your message. Visual elements not only break up text but also make complex information more digestible. From personal photos to professional graphics, the right images can elevate your slides and enhance understanding.
In this article, you will learn how to insert images from your local disk or a URL into a PowerPoint slide using C# and Spire.Presentation for .NET.
Install Spire.Presentation for .NET
To begin with, you need to add the DLL files included in the Spire.Presentation for.NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.
PM> Install-Package Spire.Presentation
Insert an Image from Disk to PowerPoint in C#
To insert an image from your disk to a PowerPoint document, you can use the ISlide.Shapes.AppendEmbedImage() method. The method requires the following three parameters:
- ShapeType: The type of shape for the image, typically a rectangle.
- IImageData: The data corresponding to the image you want to insert.
- RectangleF: Defines the position and size of the image.
The steps to insert an image from disk to a PowerPoint slide are as follows:
- Create a Presentation object.
- Load a PowerPoint document.
- Load an image from disk using Image.FromFile() method.
- Add the image to the image collection of the document using Presentation.Images.Append() method.
- Create a RectangleF object to specify where the image will be placed and its dimensions.
- Add the image to a specific slide at the specified position using ISlide.Shapes.AppendEmbedImage() method.
- Save the document to a different PowerPoint file.
- C#
using Spire.Presentation;
using Spire.Presentation.Drawing;
using System.Drawing;
namespace InsertImageFromDisk
{
class Program
{
static void Main(string[] args)
{
// Create a Presentation object
Presentation presentation = new Presentation();
// Load a PowerPoint file
presentation.LoadFromFile("C:\\Users\\Administrator\\Desktop\\input.pptx");
// Load an image from the given file path
Image img = Image.FromFile("C:\\Users\\Administrator\\Desktop\\logo.png");
// Add the image to the image collection of the document
IImageData image = presentation.Images.Append(img);
// Get the image width and height
int width = image.Width;
int height = image.Height;
// Specify the image position in the slide
int x = 100;
int y = 100;
// Get a specific slide
ISlide slide = presentation.Slides[0];
// Insert the image to the slide at the specified position
RectangleF rect = new RectangleF(x, y, width, height);
IEmbedImage imageShape = slide.Shapes.AppendEmbedImage(ShapeType.Rectangle, image, rect);
// Set the line fill type of the image shape to none
imageShape.Line.FillType = FillFormatType.None;
// Save the presentation to a different file
presentation.SaveToFile("InsertImage.pptx", FileFormat.Pptx2010);
// Dispose resources
presentation.Dispose();
}
}
}
Insert an Image from a URL to PowerPoint
An image from a URL can be downloaded and saved as a stream using the WebClient class. Once downloaded, it can be loaded as a System.Drawing.Image object using the Image.FromStream() method. Then, you can use the ISlide.Shapes.AppendEmbedImage() method to insert the image into the slide as an image shape.
The steps to insert an image from a URL to a PowerPoint slide are as follows:
- Create a Presentation object.
- Load a PowerPoint document.
- Read and convert an image from a URL into stream using WebClient class.
- Load the image from stream using Image.FromStream() method.
- Add the image to the image collection of the document using Presentation.Images.Append() method.
- Create a RectangleF object to specify where the image will be placed and its dimensions.
- Add the image to a specific slide at the specified position using ISlide.Shapes.AppendEmbedImage() method.
- Save the document to a different PowerPoint file.
- C#
using Spire.Presentation;
using Spire.Presentation.Drawing;
using System.Drawing;
using System.Net;
namespace InsertImageFromUrl
{
class Program
{
static void Main(string[] args)
{
// Create a Presentation object
Presentation presentation = new Presentation();
// Load a PowerPoint file
presentation.LoadFromFile("C:\\Users\\Administrator\\Desktop\\input.pptx");
// Declare a variable
Image img;
// Read an image from a URL
string imageUrl = "https://i.imgur.com/OygmMoN.png";
using (WebClient webClient = new WebClient())
{
using (Stream stream = webClient.OpenRead(imageUrl))
{
// Load the image from stream
img = Image.FromStream(stream);
}
}
// Add the image to the image collection of the document
IImageData image = presentation.Images.Append(img);
// Get the image width and height
int width = image.Width;
int height = image.Height;
// Specify the image position in the slide
int x = 100;
int y = 100;
// Get a specific slide
ISlide slide = presentation.Slides[0];
// Insert the image to the slide at the specified position
RectangleF rect = new RectangleF(x, y, width, height);
IEmbedImage imageShape = slide.Shapes.AppendEmbedImage(ShapeType.Rectangle, image, rect);
// Set the line fill type of the image shape to none
imageShape.Line.FillType = FillFormatType.None;
// Save the presentation to a different file
presentation.SaveToFile("InsertImage.pptx", FileFormat.Pptx2010);
// Dispose resources
