java 提取 powerpoint 中 smartart 图形的文本内容-k8凯发天生赢家

该文将介绍如何使用spire.presentation for java来提取ppt中smartart图形的文本内容。

首先， 准备一个文档中含有smartart图形的幻灯片文件:

提取ppt中smartart图形的文本内容代码如下：

import com.spire.presentation.presentation;
import com.spire.presentation.diagrams.ismartart;
import java.io.*;
public class extracttextfromsmartart {
    public static void main(string[] args) throws exception {
        presentation presentation = new presentation();
        presentation.loadfromfile("sample.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("below is extracted text from smartart:"   "\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();
    }
}
