Create new Presentation and set Image as Background for Slide in Java

  • To make your slides more visually appealing and attractive. An image background can add color, texture, and style to your presentation, making it more engaging and memorable for your audience.
  • To convey a message or emotion with your slides. An image background can help you communicate your main point or evoke a certain feeling with your slides, such as excitement, curiosity, or inspiration.
  • To highlight or contrast your text and other elements on your slides. An image background can help you draw attention to the most important information or objects on your slides, such as titles, headings, bullet points, charts, graphs, etc.

Please use following code to add background to your presentation:

Convert Presentation to PDF in Java

One of the challenges of creating and sharing PowerPoint presentations is that they can be large, complex, and difficult to view on different devices. That’s why many people choose to convert their PowerPoint presentations to PDF files, which offer several benefits. Here are some of the benefits of converting PowerPoint presentations to PDF files:

  • PDF files are compatible with any device and software that can open and view a PDF file. You don’t need to worry about the formatting or layout of your presentation being distorted or lost when you share it with others.
  • PDF files reduce the file size and make it easier to share and archive. You can compress your presentation and reduce its file size by up to one-third when you convert it to a PDF file.
