我正在使用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 . 此方法存在两个问题：
-
图像不保持原始尺寸（稍微拉伸） .
-
调整列/行的大小时，图像会被拉伸 . 有没有办法在没有锚点的情况下将图像插入Excel？ （与使用Excel / Insert / Picture相同）
我在Apache POI文档页面中使用以下示例：
//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();
感谢您的回答 .

顺便说一句，因为方法'resize'javadoc中的这个注释：
