通過 C# 將 ODP 轉換為 JPEG

using (var presentation = new Presentation("template.odp"))
{
    // iterate over all slides in the presentation
    foreach (var slide in presentation.Slides)
    {
        // create a full scale image
        var bitmap = slide.GetThumbnail(1f, 1f);

        // save the image to disk in JPEG format
        bitmap.Save(string.Format("Slide_{0}.jpeg", slide.SlideNumber), System.Drawing.Imaging.ImageFormat.Jpeg);
    }
}
