通过 Java 将 PPTX 转换为 JPEG

// load PPTX with Aspose.Slides
Presentation presentation = new Presentation("template.pptx");
   
    // iterate over all slides in the presentation
for (ISlide sld : presentation.getSlides()) 
{
  
  // create a full scale image of each slide
  BufferedImage bi = sld.getThumbnail(new RenderingOptions());

  // create a new file of type JPEG for every slide
  File outputfile = new File(sld.getSlideNumber() + ".jpeg");
  
  // save the slide image to disk
  ImageIO.write(bi, "jpeg", outputfile);
}
