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(); } } } - 1

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))); } } - 1

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")); } } - 1

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:) } } - 1
