该文将详细描述如何使用Spire.Presentation for Java添加、删除和隐藏PowerPoint 幻灯片，以及如何调整PowerPoint里的幻灯片顺序。

添加新幻灯片到已有的PowerPoint文档：

import com.spire.presentation.*;

public class Slides {
    public static void main(String[] args) throws Exception {

        //创建一个PowerPoint文档并加载示例文档

        Presentation presentation = new Presentation();
        presentation.loadFromFile("C:\\Users\\Administrator\\Desktop\\Sample.pptx");
        
        //在文档末尾添加新幻灯
        presentation.getSlides().append();

        //在第二页插入空白幻灯片
        presentation.getSlides().insert(1);

       //保存文档
        presentation.saveToFile("output/AddSlide.pptx", FileFormat.PPTX_2010);
    }

}

隐藏幻灯片

import com.spire.presentation.*;

public class Slides {
    public static void main(String[] args) throws Exception {

        //创建一个PowerPoint文档并加载示例文档
        Presentation presentation = new Presentation();
        presentation.loadFromFile("C:\\Users\\Administrator\\Desktop\\Sample.pptx");

        //隐藏第二张幻灯片
        presentation.getSlides().get(1).setHidden(true);

        //保存文档
        presentation.saveToFile("output/Hideslide.pptx", FileFormat.PPTX_2010);
    }

}

删除幻灯片

import com.spire.presentation.*;

public class Slides {
    public static void main(String[] args) throws Exception {

        //创建一个PowerPoint文档并加载示例文档
        Presentation presentation = new Presentation();
        presentation.loadFromFile("C:\\Users\\Administrator\\Desktop\\Sample.pptx");

        //删除第二张幻灯片
        presentation.getSlides().removeAt(1);

        //保存文档
        presentation.saveToFile("output/Removeslide.pptx", FileFormat.PPTX_2010);
    }

}

调整幻灯片顺序

import com.spire.presentation.*;

public class Slides {
    public static void main(String[] args) throws Exception {

        //创建一个PowerPoint文档并加载示例文档
        Presentation presentation = new Presentation();
        presentation.loadFromFile("C:\\Users\\Administrator\\Desktop\\Sample.pptx");

        //获取文档中的第一张幻灯片并将其设置为第二张
        ISlide slide = presentation.getSlides().get(0);
        slide.setSlideNumber(2);

       //保存文档
        presentation.saveToFile("output/Reorderslide.pptx", FileFormat.PPTX_2010);
    }

}
