一, 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(); } } }

二、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)));    
           }    
    
       }

三、操作文本对象

import java.awt.Color; 
             import java.awt.Rectangle; 
             import java.io.FileOutputStream; 
    
             import org.apache.poi.hslf.model.AutoShape; 
             import org.apache.poi.hslf.model.Line; 
             import org.apache.poi.hslf.model.ShapeTypes; 
             import org.apache.poi.hslf.model.Slide; 
             import org.apache.poi.hslf.model.TextBox; 
             import org.apache.poi.hslf.model.TextRun; 
             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")); 
    
                 }    
    
             }

四、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:)    
           }    
       }
