從 .xls 文件中讀取圖像及其位置的參考

Question

在我的一個項目中，我需要從.xls文件中讀取圖像。 對於每一行，有一列包含我需要讀出的圖像。

看起來我可以一起閱讀所有圖像，但是我怎樣才能獲得每個圖像的位置，例如列號和行號，以便我可以將這些圖像與其他數據相關聯？

只要形狀是圖片，以下都是可能的：

import org.apache.poi.hssf.usermodel.*;
import org.apache.poi.ss.usermodel.*;
import org.apache.poi.ss.util.*;
import org.apache.poi.openxml4j.exceptions.InvalidFormatException;

import java.io.FileOutputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.FileInputStream;
import java.io.InputStream;

class GetShapePosition {

 public static void main(String[] args) {
  try {

   InputStream inp = new FileInputStream("workbook.xls");
   Workbook wb = WorkbookFactory.create(inp);

   HSSFSheet sheet = (HSSFSheet)wb.getSheetAt(0);

   HSSFPatriarch dravingPatriarch = sheet.getDrawingPatriarch();

   java.util.List<HSSFShape> shapes = dravingPatriarch.getChildren();

   for (HSSFShape shape : shapes) {
    if (shape instanceof HSSFPicture) {
     HSSFPicture hssfPicture = (HSSFPicture)shape;
     int picIndex = hssfPicture.getPictureIndex();
     String filename = hssfPicture.getFileName();
     int row = hssfPicture.getClientAnchor().getRow1();
     int col = hssfPicture.getClientAnchor().getCol1();
     System.out.println("Picture " + picIndex + " with Filename: " + filename + " is located row: " + row + ", col: " + col);
    }
  }

  } catch (InvalidFormatException ifex) {
  } catch (FileNotFoundException fnfex) {
  } catch (IOException ioex) {
  }
 }
}
