Jar文件获取及导入：

方法1：官网下载jar文件包。下载后，解压文件，并在java程序中导入lib文件夹下的Spire.Presentation.jar文件。

方法2：可通过maven仓库导入到maven项目。

Java代码示例

测试文档：

【示例1】读取PPT中的文本

import com.spire.presentation.IAutoShape;import com.spire.presentation.ISlide;import com.spire.presentation.ParagraphEx;import com.spire.presentation.Presentation;import java.io.FileWriter;public class ExtractText { public static void main(String[]args) throws Exception{  //加载测试文档  Presentation ppt = new Presentation();  ppt.loadFromFile("test.pptx");  StringBuilder buffer = new StringBuilder();  //遍历文档中的幻灯片，提取文本  for (Object slide : ppt.getSlides()) {   for (Object shape : ((ISlide) slide).getShapes()) {    if (shape instanceof IAutoShape) {     for (Object tp : ((IAutoShape) shape).getTextFrame().getParagraphs()) {      buffer.append(((ParagraphEx) tp).getText());     }    }   }  }  //保存到文本文件  FileWriter writer = new FileWriter("ExtractText.txt");  writer.write(buffer.toString());  writer.flush();  writer.close(); }}

文本读取结果：

【示例2】读取PPT中的所有图片

import com.spire.presentation.Presentation;import javax.imageio.ImageIO;import java.awt.image.BufferedImage;import java.io.File;public class ExtractAllImgs { public static void main(String[] args) throws Exception {  //加载文档  Presentation ppt = new Presentation();  ppt.loadFromFile("test.pptx");  //提取文档中的所有图片  for (int i = 0; i < ppt.getImages().getCount(); i++) {   BufferedImage image = ppt.getImages().get(i).getImage();   ImageIO.write(image, "PNG", new File(String.format("AllImage-%1$s.png", i)));  } }}

【示例3】读取指定幻灯片中的图片

import com.spire.presentation.*;import javax.imageio.ImageIO;import java.awt.image.BufferedImage;import java.io.File;public class ExtractImgsInSpecifiedSlide { public static void main(String[]args) throws Exception{  //加载文档  Presentation ppt = new Presentation();  ppt.loadFromFile("test.pptx");  //获取第2张幻灯片  ISlide slide = ppt.getSlides().get(1);  //提取图片  for(int i = 0; i< slide.getShapes().getCount(); i++)  {   IShape shape = slide.getShapes().get(i);   if(shape instanceof SlidePicture)   {    SlidePicture pic = (SlidePicture) shape;    BufferedImage image = pic.getPictureFill().getPicture().getEmbedImage().getImage();    ImageIO.write(image, "PNG", new File(String.format("extractImageinslide-%1$s.png", i)));   }   if(shape instanceof PictureShape)   {    PictureShape ps = (PictureShape) shape;    BufferedImage image = ps.getEmbedImage().getImage();    ImageIO.write(image, "PNG", new File(String.format("extractImageinslide-%1$s.png", i)));   }  } }}
