不带锚点的Apache POI插入映像

Question

我使用Apache POI在Java中创建Excel文件，它可以工作，但插入的图像锚定到列/行。这种方法有2个问题：

//create a new workbook
Workbook wb = new XSSFWorkbook(); //or new HSSFWorkbook();

//add picture data to this workbook.
InputStream is = new FileInputStream("image1.jpeg");
byte[] bytes = IOUtils.toByteArray(is);
int pictureIdx = wb.addPicture(bytes, Workbook.PICTURE_TYPE_JPEG);
is.close();

CreationHelper helper = wb.getCreationHelper();

//create sheet
Sheet sheet = wb.createSheet();

// Create the drawing patriarch.  This is the top level container for all shapes. 
Drawing drawing = sheet.createDrawingPatriarch();

//add a picture shape
ClientAnchor anchor = helper.createClientAnchor();
//set top-left corner of the picture,
//subsequent call of Picture#resize() will operate relative to it
anchor.setCol1(3);
anchor.setRow1(2);
Picture pict = drawing.createPicture(anchor, pictureIdx);

//auto-size picture relative to its top-left corner
pict.resize();

//save workbook
String file = "picture.xls";
if(wb instanceof XSSFWorkbook) file += "x";
FileOutputStream fileOut = new FileOutputStream(file);
wb.write(fileOut);
fileOut.close();

谢谢你的回答。

可以肯定的是，由于方法“resize”中的这个注释，Javadoc：

请注意，此方法仅适用于默认字体大小的工作簿（Arial 10pt用于.xls,Calibri11pt用于.xlsx）。如果更改了默认字体，则调整大小的图像可以垂直或水平地排列。
