（使用工具： Free Spire.Presentation for Java）
JAR包导入
方法一：下载Free Spire.Presentation for Java包并解压缩，然后将lib文件夹下的jar包作为依赖项直接导入到Java应用程序中。
方法二：通过Maven仓库安装jar包，配置pom.xml文件的代码如下：
<repositories>
<repository>
<id>com.e-iceblue</id>
<url>http://repo.e-iceblue.cn/repository/maven-public/</url>
</repository></repositories><dependencies>
<dependency>
<groupId>e-iceblue</groupId>
<artifactId>spire.presentation.free</artifactId>
<version>3.9.0</version>
</dependency></dependencies>
Java代码示例
import com.spire.presentation.Presentation;
import com.spire.presentation.diagrams.ISmartArt;import java.io.*;
//java项目www.fhadmin.org
public class extractTextFromSmartArt { public static void main(String[] args) throws Exception {
Presentation presentation = new Presentation();
presentation.loadFromFile("SmartArt.pptx"); //新建txt文档
String result = "output/extractTextFromSmartArt.txt";
File file=new File(result); if(file.exists()){
file.delete();
}
file.createNewFile();
FileWriter fw =new FileWriter(file,true);
BufferedWriter bw =new BufferedWriter(fw);
bw.write("以下内容为从SmartArt中提取到的文本:" + "\r\n"); //遍历所有幻灯片并获取SmartArt图形.
for (int i = 0; i < presentation.getSlides().getCount(); i++)
{ for (int j = 0; j < presentation.getSlides().get(i).getShapes().getCount(); j++)
{ if (presentation.getSlides().get(i).getShapes().get(j) instanceof ISmartArt)
{
ISmartArt smartArt = (ISmartArt)presentation.getSlides().get(i).getShapes().get(j); //提取SmartArt中的文本
for (int k = 0; k < smartArt.getNodes().getCount(); k++)
{
bw.write(smartArt.getNodes().get(k).getTextFrame().getText() + "\r\n");
}
}
}
}
bw.flush();
bw.close();
fw.close();
}
}
代码运行结果：
