如何使用Java和Apache POI在具有自定義尺寸的xls中寫入圖像

Question

如何使用Java和Apache POI在xls中寫入具有自定義大小的圖像？ 這是我的代碼。 它顯示具有默認尺寸的給定圖像，但我需要自定義尺寸。

Workbook wb = new XSSFWorkbook();
Sheet sheet = wb.createSheet("My Sample Excel");
InputStream inputStream = new FileInputStream("images/myLogo.png");
byte[] bytes = IOUtils.toByteArray(inputStream);
int pictureIdx = wb.addPicture(bytes, Workbook.PICTURE_TYPE_PNG);
inputStream.close();
CreationHelper helper = wb.getCreationHelper();
Drawing drawing = sheet.createDrawingPatriarch();
ClientAnchor anchor = helper.createClientAnchor();
anchor.setCol1(1);
anchor.setRow1(2);
Picture pict = drawing.createPicture(anchor, pictureIdx);
pict.resize();
FileOutputStream fileOut = null;
fileOut = new FileOutputStream("data/myFile.xlsx");
wb.write(fileOut);
fileOut.close();

謝謝。

嘗試在調用drawing.createPicture之前運行它們：

anchor.setAnchorType(ClientAnchor.MOVE_AND_RESIZE);
anchor.setCol2(X);
anchor.setRow2(Y);
