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 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"));    

             }    

         }

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:)

       }

   }
