Convert Presentations to Animated GIF Using Default Settings

This sample code shows you how to convert a presentation to animated GIF using standard settings:

  $pres = new Presentation("pres.pptx");
  try {
    $pres->save("pres.gif", SaveFormat::Gif);
  } finally {
    if (!java_is_null($pres)) {
      $pres->dispose();
    }
  }

The animated GIF will be created with default parameters.

    $gifOptions->setDefaultDelay(2000);// how long each slide will be showed until it will be changed to the next one

    $gifOptions->setTransitionFps(35);// increase FPS to better transition animation quality

FAQ

What if the fonts used in the presentation aren’t installed on the system?

Install the missing fonts or configure fallback fonts. Aspose.Slides will substitute, but the appearance may differ. For branding, always ensure the required typefaces are explicitly available.

Can I overlay a watermark on the GIF frames?

Yes. Add a semi-transparent object/logo to the master slide or to individual slides before export — the watermark will appear on every frame.
