Aspose.Slides v21.12C#和Java支持摘要放大和分段放大，以.NET代码为例：

using (Presentation pres = new Presentation())
{
   //Adds a new slide to the presentation
   ISlide slide = pres.Slides.AddEmptySlide(pres.Slides[0].LayoutSlide);
   slide.Background.FillFormat.FillType = FillType.Solid;
   slide.Background.FillFormat.SolidFillColor.Color = Color.Brown;
   slide.Background.Type = BackgroundType.OwnBackground;

   // Adds a new section to the presentation
   pres.Sections.AddSection("Section 1", slide);

   //Adds a new slide to the presentation
   slide = pres.Slides.AddEmptySlide(pres.Slides[0].LayoutSlide);
   slide.Background.FillFormat.FillType = FillType.Solid;
   slide.Background.FillFormat.SolidFillColor.Color = Color.Aqua;
   slide.Background.Type = BackgroundType.OwnBackground;

   // Adds a new section to the presentation
   pres.Sections.AddSection("Section 2", slide);

   //Adds a new slide to the presentation
   slide = pres.Slides.AddEmptySlide(pres.Slides[0].LayoutSlide);
   slide.Background.FillFormat.FillType = FillType.Solid;
   slide.Background.FillFormat.SolidFillColor.Color = Color.Chartreuse;
   slide.Background.Type = BackgroundType.OwnBackground;

   // Adds a new section to the presentation
   pres.Sections.AddSection("Section 3", slide);

   //Adds a new slide to the presentation
   slide = pres.Slides.AddEmptySlide(pres.Slides[0].LayoutSlide);
   slide.Background.FillFormat.FillType = FillType.Solid;
   slide.Background.FillFormat.SolidFillColor.Color = Color.DarkGreen;
   slide.Background.Type = BackgroundType.OwnBackground;

   // Adds a new section to the presentation
   pres.Sections.AddSection("Section 4", slide);

   // Adds a SectionZoomFrame object
   ISectionZoomFrame sectionZoomFrame = pres.Slides[0].Shapes.AddSectionZoomFrame(20, 20, 300, 200, pres.Sections[1]);

   // Adds SummaryZoomFrame object
   ISummaryZoomFrame summaryZoomFrame = pres.Slides[0].Shapes.AddSummaryZoomFrame(350, 50, 300, 200);

   // Saves the presentation
   pres.Save("presentation.pptx", SaveFormat.Pptx);
}

PPT转PDF低代码API优化，以C#代码为例，一行解决功能：

Convert.AutoByExtension("pres.pptx", "pres.pdf")

ObjectData、EmbeddedFileExtension和EmbeddedFileData已从IOleObjectFrame接口中删除

过时的属性ObjectData、EmbeddedFileExtension和EmbeddedFileData已经从IOleObjectFrame接口中移除。使用IOleObjectFrame接口的SetEmbeddedData方法和EmbeddedData属性来代替。
