Apache POI PPT - 读取图形

• 

  简述

  您可以使用 XSLFShape 类的方法 getShapeName() 来计算演示文稿中使用的形状数量。 下面给出的是从演示文稿中读取形状的程序 −

  
  
  import java.io.File;
  
  import java.io.FileInputStream;
  
  import java.io.FileOutputStream;
  
  import java.io.IOException;
  
  import java.util.List;
  
  import org.apache.poi.xslf.usermodel.XMLSlideShow;
  
  import org.apache.poi.xslf.usermodel.XSLFShape;
  
  import org.apache.poi.xslf.usermodel.XSLFSlide;
  
  
  
  public class ReadingShapes {
  
     public static void main(String args[]) throws IOException {
  
        //creating a slideshow 
  
        File file = new File("shapes.pptx");
  
        XMLSlideShow ppt = new XMLSlideShow(new FileInputStream(file));
  
        
  
        //get slides 
  
        List<XSLFSlide> slide = ppt.getSlides();
  
        
  
        //getting the shapes in the presentation
  
        System.out.println("Shapes in the presentation:");
  
        for (int i = 0; i < slide.size(); i++){
  
           List<XSLFShape> sh = slide.get(i).getShapes();
  
           for (int j = 0; j < sh.size(); j++){
  
              //name of the shape
  
              System.out.println(sh.get(j).getShapeName());
  
           }
  
        }
  
        FileOutputStream out = new FileOutputStream(file);
  
        ppt.write(out);
  
        out.close();   
  
     }
  
  }
  
  

  将上面的Java代码保存为ReadingShapes.java，然后在命令提示符下编译执行如下 −

  
  
  $javac ReadingShapes.java
  
  $java ReadingShapes
  
  

  它将编译并执行以生成以下输出。

  
  
  Shapes in the presentation: 
  
  Rectangle 1
  
  Oval 1
  
  Isosceles Triangle 1
  
  

  新添加的各种形状的幻灯片如下所示−
