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

import java.awt.Color;
         import java.awt.Rectangle;

         import org.apache.poi.hslf.usermodel.RichTextRun;
         import org.apache.poi.hslf.usermodel.SlideShow;    
         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();
                 _textRun.setRawText("杜磊米");
                 _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();
                 _autoText.setRawText("杜磊米");
                 _autoShape.setAnchor(new Rectangle(200,200,100,100));
                 _autoShape.setFillColor(new Color(170,215,255));
                 _autoShape.setLineWidth(5.0);
                 _autoShape.setLineStyle(Line.LINE_DOUBLE);    
                 // AutoShape 对象可以设置多个不同样式文本
                 TextRun _autoText2 = _autoShape.createTextRun();
                 RichTextRun _richText = _autoText2.appendText("杜");
                 _richText.setFontColor(new Color(255,255,255));
                 RichTextRun _richText2 = _autoText2.appendText("磊米");
                 _richText2.setFontColor(new Color(255,0,0));
                 _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.awt.Dimension;
   import java.io.FileOutputStream;    
   import org.apache.poi.hpsf.DocumentSummaryInformation;
   import org.apache.poi.hpsf.SummaryInformation;
   import org.apache.poi.hslf.HSLFSlideShow;
   import org.apache.poi.hslf.model.Slide;
   import org.apache.poi.hslf.usermodel.SlideShow;    
   public class PPTProperty {
       public static void main(String [] args)throws Exception{    
           HSLFSlideShow hslf = HSLFSlideShow.create();
           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:)
       }
