C++ PowerPoint API
Aspose.Slides for C++ is designed to automate PowerPoint presentation manipulation features within C++ applications. Using the API, you can create, edit, or convert the PowerPoint presentations seamlessly. You can download the complete package of the API files or get it from NuGet.
Create a PowerPoint Presentation in C++
Let’s start by creating an empty PowerPoint presentation using Aspose.Slides for C++. The following are the steps to perform this operation.
- Create an object of the Presentation class.
- Save the presentation using Presentation->Save(String, SaveFormat::Pptx) method.
The following code sample shows how to create a PowerPoint presentation using C++.
Add Slide to a Presentation in C++
Once you have created the PowerPoint presentation, you can insert slides into it. The following are the steps to add slides to a PowerPoint presentation:
- Create an object of the Presentation class.
- Get slides in the ISlideCollection object using Presentation->get_Slides() method.
- Add slide using ISlideCollection->AddEmptySlide() method.
- Save the presentation using Presentation->Save(String, SaveFormat::Pptx) method.
The following code sample shows how to add slides to a PowerPoint presentation using C++.

Add Text to a PowerPoint Slide using C++
Now, let’s add text to a slide in the PowerPoint presentation. For this, you need to insert a textbox to the slide. Below are the steps to perform this operation.
- Create a new presentation or load an existing one using Presentation class.
- Obtain the reference of the slide into ISlide object using Presentation->get_Slides()->idx_get(int) method.
- Add a rectangle to the slide using ISlide->get_Shapes()->AddAutoShape(ShapeType::Rectangle, int, int, int, int) method and get its reference in IAutoShape object.
- Add text frame using IAutoShape->AddTextFrame(u" “) method.
- Get the text frame using IAutoShape->get_TextFrame() into ITextFrame object.
- Get paragraph using ITextFrame->get_Paragraphs()->idx_get(0) into IParagraph object.
- Access portion of the paragraph using IParagraph->get_Portions()->idx_get(0) into IPortion object.
- Set text using IPortion->set_Text(u"Aspose TextBox”) method.
- Save the presentation using Presentation->Save(String, SaveFormat::Pptx) method.

Create a Table in Presentation using C++
The following are the steps to add a table in a PowerPoint presentation’s slide using Aspose.Slides for C++.
- Create an instance of a Presentation class.
- Obtain the reference of a slide into an ISlide object.
- Define arrays of columns and rows by providing the width.
- Add a table to the slide using ISlide->get_Shapes()->AddTable() method.
- Iterate through each cell to apply formatting to the top, bottom, right, and left borders.
- Merge cells if required.
- Access the text frame of a cell to add some text.
- Save the presentation as a PPTX file.

Create a Chart in Presentation using C++
Aspose.Slides for C++ supports various types of charts such as scattered, treemap, histogram, and etc. For the demonstration, let’s create a normal chart. Below are the steps to perform this operation.
- Create an instance of the Presentation class.
- Obtain the reference of a slide you want to add the chart on.
- Add chart with default data along with desired type using ISlide->get_Shapes()->AddChart() method.
- Get the reference of the chart in the IChart object.
- Clear the chart data and add new series and categories.
- Add new chart data for chart series.
- Set fill color for chart series.
- Add chart series labels.
- Save the presentation as a PPTX file.
The following code sample shows how to insert a chart in a PowerPoint presentation using C++.

Open a PowerPoint Presentation in C++
You can also open an existing PowerPoint presentations in order to edit the content. For this, you can follow the below steps:
- Load the PPTX file using Presentation class by providing the file’s name.
- Update the content of the presentation.
- Save the updated file using the Presentation->Save(String, SaveFormat) method.
The following code sample shows how to open an existing PowerPoint presentation using C++.
