Import PowerPoint from PDF

In this case, you get to convert a PDF to a PowerPoint presentation.

1. Create an instance of the Presentation class.
2. Call the addFromPdf() method and pass the PDF file.
3. Use the save() method to save the file in the PowerPoint format.

This Java code demonstrates the PDF to PowerPoint operation:

Presentation pres = new Presentation();
try {
    pres.getSlides().addFromPdf("InputPDF.pdf");
    pres.save("OutputPresentation.pptx", SaveFormat.Pptx);
} finally {
    if (pres != null) pres.dispose();
