java - 使用 Apache POI 获取 .xlsx 文件中图像的图像位置/位置

Question

我只能通过.getAllPictures()这个方法获取图片数据

List<XSSFPictureData> lst = (List)workbook.getAllPictures();

每当我使用 getShapes()

时我都会得到这个

是否有可能或有什么方法可以让我在 .xlsx 文件中获取图像位置/位置？

您可以通过 XSSFPicture.getClientAnchor() 方法检索位置，ClientAnchor 有一个行/列位置和一个像素偏移量，应该允许获取您要查找的信息，例如:

XSSFDrawing dp = wb.getSheetAt(0).createDrawingPatriarch();
List<XSSFShape> pics = dp.getShapes();
XSSFPicture inpPic = (XSSFPicture)pics.get(0);

XSSFClientAnchor clientAnchor = inpPic.getClientAnchor();

System.out.println("col1: " + clientAnchor.getCol1() + ", col2: " + clientAnchor.getCol2() + ", row1: " + clientAnchor.getRow1() + ", row2: " + clientAnchor.getRow2());
System.out.println("x1: " + clientAnchor.getDx1() + ", x2: " + clientAnchor.getDx2() +  ", y1: " + clientAnchor.getDy1() +  ", y2: " + clientAnchor.getDy2());

会打印出类似的东西

col1: 0, col2: 2, row1: 1, row2: 7
x1: 252000, x2: 63720, y1: 60480, y2: 201600
