Java 利用POI操作PPT

解析PPT文件中的图片

import java.io.File;    
    import java.io.FileOutputStream;    

    import org.apache.poi.hslf.HSLFSlideShow;    
    import org.apache.poi.hslf.model.Picture;    
    import org.apache.poi.hslf.usermodel.PictureData;    
    import org.apache.poi.hslf.usermodel.SlideShow;    

   public class OutputPicture {    
       // 图片默认存放路径    
       public final static String path = "F:\ppt";    

       public static void main(String[] args) throws Exception {    
           // 加载PPT    
           HSLFSlideShow _hslf = new HSLFSlideShow("F:\Downloads\myPPT.ppt");    
           SlideShow _slideShow = new SlideShow(_hslf);    

           // 获取PPT文件中的图片数据    
           PictureData[] _pictures = _slideShow.getPictureData();    

           // 循环读取图片数据    
           for (int i = 0; i < _pictures.length; i++) {    
               StringBuilder fileName = new StringBuilder(path);    
               PictureData pic_data = _pictures[i];    
               fileName.append(i);    
               // 设置格式    
               switch (pic_data.getType()) {    
             case Picture.JPEG:    
                   fileName.append(".jpg");    
                   break;    
               case Picture.PNG:    
                   fileName.append(".png");    
                   break;    
               default:    
                   fileName.append(".data");    
               }    
               // 输出文件    
               FileOutputStream fileOut = new FileOutputStream(new File(fileName.toString()));    
               fileOut.write(pic_data.getData());    
               fileOut.close();    
           }    
       }    
   }   

在PPT文件中加入外部图片

import java.awt.Rectangle;    
   import java.awt.image.BufferedImage;    
   import java.io.File;    
   import java.io.FileOutputStream;    
   import javax.imageio.ImageIO;    
   import org.apache.poi.hslf.model.Picture;    
   import org.apache.poi.hslf.model.Slide;    
   import org.apache.poi.hslf.usermodel.SlideShow;    


   public class InputPicture {    

       public static String path = "F:\images\myImage.png";    
       public static String OUTPUT = "F:\ppt\myppt.ppt";    

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

           if(args.length != 0){    
               path = args[0];    
           }    
           // 构建PPT    
           SlideShow _slideShow = new SlideShow();    
           // 创建幻灯片    
           Slide _slide = _slideShow.createSlide();    

           // 设置图片类型    
           int pic_type = -1;    
           if(path.indexOf(".png") != -1){    
               pic_type = Picture.PNG;    
           }else{    
               pic_type = Picture.JPEG;    
           }    
           File file = new File(path);    
           BufferedImage image = ImageIO.read(file);    
           // 新置入图片索引位置    
          int newIndex = _slideShow.addPicture(file, pic_type);    
           // 根据索引位置 , 创建图片对象    
          Picture _picture = new Picture(newIndex);    
           // 设置图片显示位置    
           _picture.setAnchor(new Rectangle(100,100,image.getWidth(),image.getHeight()));    

           // 将图片放入幻灯片    
           _slide.addShape(_picture);    
           // 输出PPT文件    
           _slideShow.write(new FileOutputStream(new File(OUTPUT)));    
       }    

   }  

操作文本对象

         public class InputTextRun {    

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

                 SlideShow _slideShow = new SlideShow();    
                 Slide slide = _slideShow.createSlide();    

                 // 创建并置入简单文本    
                 TextBox _text = new TextBox();    
                 TextRun _textRun = _text.createTextRun();

                 _text.setAnchor(new Rectangle(10,10,100,100));    

                 // 创建并置入带有样式的文本    
                 AutoShape _autoShape = new AutoShape(ShapeTypes.Rectangle); //设置形状    
                TextRun _autoText = _autoShape.createTextRun();

                 _richText2.setFontSize(12);    

                 // 将文本对象置入幻灯片    
                 slide.addShape(_text);    
                 slide.addShape(_autoShape);    

                 // 输出文件    
                 _slideShow.write(new FileOutputStream("F:\ppt\text.ppt"));    

             }    

         }  

设置各类文件属性

   import java.io.FileOutputStream;    

   import org.apache.poi.hpsf.DocumentSummaryInformation;    
   import org.apache.poi.hpsf.SummaryInformation;

           SlideShow _slideShow = new SlideShow(hslf);    
           // 设置页面大小    
           _slideShow.setPageSize(new Dimension(400,600));    
           // 设置后创建出相应大小的幻灯片    
           Slide slide = _slideShow.createSlide();    

           DocumentSummaryInformation doc = hslf.getDocumentSummaryInformation();    
           SummaryInformation info = hslf.getSummaryInformation();    

           doc.setCompany("secret");    
           info.setAuthor("杜磊米");    
           info.setTitle("nothing");    
           // 输出文件    
           _slideShow.write(new FileOutputStream("F:\ppt\demo.ppt"));    

           // 完成后, 找到文件 , 右键属性查看:)    
       }
