Create a PowerPoint Presentation using Java

To begin with the PowerPoint automation, let’s first create an empty presentation document and save it as a PPTX file. The following are the steps to create a presentation document.

The following code sample shows how to create a PowerPoint presentation using Java.

Open an Existing PowerPoint Presentation using Java

Aspose.Slides for Java also allows you to open existing PowerPoint presentations in order to update their content. The following are the steps to load a PowerPoint PPTX file.

Create a Table in Presentation using Java

Table is an important element that is used to organize the content in the form of rows and columns. For adding table to a slide, you can following the below steps.

  • Create an instance of the Presentation class and provide the PPTX file’s path to its constructor.
  • Get the reference of the slide you want to add the text to.
  • Create an array of columns’ width.
  • Create an array of rows’ height.
  • Add a Table to the slide using ISlide.getShapes().addTable() method and get its reference to ITable object.
  • Iterate through each cell to apply formatting to the Top, Bottom, Right and Left Borders.
  • Add some text to the cell.
  • Save the updated presentation using Presentation.save(String, SaveFormat) method.
