我可以获取图片文件,但我不知道如何获取图片的位置。 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++;
}
最佳答案
还有另一种方法可以从 XSSFSheet 获取位置信息。
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();
}
}
}
