Java 如何使用ApachePOI获取xlsx文件中图片的位置

我可以得到图片文件，但我不知道如何得到图片的位置。 我在POI中找不到正确的方法

    InputStream is= new FileInputStream("test.xlsx");  
    XSSFWorkbook workbook = new XSSFWorkbook(is);  

    List<PictureData> list = (List)workbook.getAllPictures();
    int i = 0;
    System.out.println(list.size());
    for(Iterator<PictureData> it = list.iterator(); it.hasNext(); ){
        PictureData pd = it.next();
        savePic(i, pd);
        i++;
    }

InputStream is=新文件InputStream（“test.xlsx”）；
XSSF工作簿=新XSSF工作簿（is）；
列表=（列表）工作簿。getAllPictures（）；
int i=0；
System.out.println（list.size（））；
for（Iterator it=list.Iterator（）；it.hasNext（）；）{
PictureData pd=it.next（）；
savePic（i，pd）；
i++；
}

getAllPictures（）是如何实现的：使用getRelations（）查询XSSFSheet（inSheet）并查找XSSFDrawing

CTDrawing类提供了几种获取图片锚定的方法

for(POIXMLDocumentPart dr : inSheet.getRelations()) {
    if(dr instanceof XSSFDrawing) {
        CTDrawing ctDrawing = ((XSSFDrawing) dr).getCTDrawing();
        for (CTTwoCellAnchor anchor: ctDrawing.getTwoCellAnchorList()) {
            CTMarker from = anchor.getFrom();
            int row1 = from.getRow();
            int col1 = from.getCol();

            CTMarker to = anchor.getTo();
            int row2 = to.getRow();
            int col2 = to.getCol();

            // do something here
        }
    }
}

以下是getAllPictures（）的实现方式：使用getRelations（）查询XSSFSheet（inSheet）并查找XSSFDrawing

for(POIXMLDocumentPart dr : inSheet.getRelations()) {
    if(dr instanceof XSSFDrawing) {
        CTDrawing ctDrawing = ((XSSFDrawing) dr).getCTDrawing();
        for (CTTwoCellAnchor anchor: ctDrawing.getTwoCellAnchorList()) {
            CTMarker from = anchor.getFrom();
            int row1 = from.getRow();
            int col1 = from.getCol();

            CTMarker to = anchor.getTo();
            int row2 = to.getRow();
            int col2 = to.getCol();

            // do something here
        }
    }
}

还有另一种从XSSFSheet获取位置信息的方法

        XSSFSheet sheet = workBook.getSheetAt(0);
        XSSFDrawing drawing = sheet.createDrawingPatriarch(); // I know it is ugly, actually you get the actual instance here
        for (XSSFShape shape : drawing.getShapes()) {
            if (shape instanceof XSSFPicture) {
                XSSFPicture picture = (XSSFPicture) shape;
                XSSFPictureData xssfPictureData = picture.getPictureData();
                ClientAnchor anchor = picture.getPreferredSize();
                int row1 = anchor.getRow1();
                int row2 = anchor.getRow2();
                int col1 = anchor.getCol1();
                int col2 = anchor.getCol2();
                System.out.println("Row1: " + row1 + " Row2: " + row2);
                System.out.println("Column1: " + col1 + " Column2: " + col2);
                // Saving the file
                String ext = xssfPictureData.suggestFileExtension();                
                byte[] data = xssfPictureData.getData();
                String filePath = "C:\\..\\Images\\" + xssfPictureData.getPackagePart().getPartName();
                try (FileOutputStream os = new FileOutputStream(filePath)) {
                    os.write(data);
                    os.flush();         
                }

            }
        }
