问题描述
在我的项目,我需要从的.xls
文件读取的图像之一。对于每一行有含有我需要读出图像的一列。
In one of my projects I need to read images from an .xls
file. For each row there is a column containing an image which I need to read out.
它看起来像我可以读取所有的图像在一起,但我怎么也可以获取每个图像的位置,像列和行号,这样我就可以与其他数据与这些图片?
It looks like I can read all the images together, but how can I also get the position of each image, like column and row numbers, so I can relate those images with other data?
推荐答案
只要形状的图片,以下是可能的:
As long as the shapes are pictures, the following is possible:
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) {
}
}
}
