@xiaoman,

请参阅以下示例代码来完成您的任务。请参考它，然后根据您的需要编写/更新您的代码。
例如，
示例代码：

//Open the Excel file
Workbook workbook = new Workbook("d:\\files\\Book1.xlsx");
Worksheet worksheet = workbook.getWorksheets().get(0);

//Get all the images in the worksheet
PictureCollection pictures = worksheet.getPictures();

for (int i = 0; i < pictures.getCount(); i++)
{
            Picture picture = pictures.get(i);

            //Get the cell containing the picture
            int row = picture.getUpperLeftRow();
            int column = picture.getUpperLeftColumn();
            Cell cell = worksheet.getCells().get(row, column);

            
            double cellWidth = worksheet.getCells().getColumnWidthPixel(column);
            double cellHeight = worksheet.getCells().getRowHeightPixel(row);

            //Get the original dimensions of the picture
            double picWidth = picture.getWidth();
            double picHeight = picture.getHeight();

            //Calculate the scale factors to fit the image within the cell
            double scaleX = cellWidth / picWidth;
            double scaleY = cellHeight / picHeight;

            //Choose the smaller scale to maintain the aspect ratio
            double scale = Math.min(scaleX, scaleY);

            //Resize the picture
            picture.setWidth((int)(picWidth * scale));
            picture.setHeight((int)(picHeight * scale));

            //Center the image within the cell by adjusting the left and top offsets
            int leftOffset = (int)((cellWidth - picture.getWidth()) / 2);
            int topOffset = (int)((cellHeight - picture.getHeight()) / 2);
            picture.setLeft(leftOffset);
            picture.setTop(topOffset);
}

//Save the updated workbook
workbook.save("d:\\files\\out1.xlsx");

希望这会有所帮助。

你可以使用单元格嵌入图片来实现需求，请查看附件。result.zip (4.1 MB)

样例代码如下：

//Open the Excel file
Workbook workbook = new Workbook(filePath + "sample.xlsx");
Worksheet worksheet = workbook.getWorksheets().get(0);

//Get all the images in the worksheet
PictureCollection pictures = worksheet.getPictures();

for (int i = 0; i < pictures.getCount(); i++)
{
            Picture picture = pictures.get(i);

            //Get the cell containing the picture
            int row = picture.getUpperLeftRow();
            int column = picture.getUpperLeftColumn();
            Cell cell = worksheet.getCells().get(row, column);

            Style style = cell.getStyle();
            style.setHorizontalAlignment(TextAlignmentType.CENTER);
            style.setVerticalAlignment(TextAlignmentType.CENTER);
            
            cell.setEmbeddedImage(picture.getData());
            cell.setStyle(style);
}
pictures.clear();

//Save the updated workbook
workbook.save(filePath + "out_java.xlsx");

好像并不行

请提供你的样例文件，你可以压缩成zip格式并上传到这里。我们很快就会检查。另外，请注意，单元格嵌入图片功能是高版本Excel才支持的，你需要使用office 365进行查看。

@xiaoman ,

放在单元格中的图片(Placed in Cell Picture)是Microsoft Excel的新的特性，如果你使用的是WPS或者低版本的Microsoft Excel，此特性可能没有支持。
