要支持复制行图片,需要修改copyRow()方法,并添加处理图像的逻辑。以下是修改后的代码示例:
private void copyRow(Row source, Row target, Workbook workbook) {
// 遍历源行的每个单元格
for (int i = source.getFirstCellNum(); i <= source.getLastCellNum(); i++) {
Cell sourceCell = source.getCell(i);
// 如果源单元格为null,则不创建新单元格
if (sourceCell != null) {
Cell targetCell = target.createCell(i, sourceCell.getCellType());
// 复制单元格样式(如果需要)
CellStyle sourceCellStyle = sourceCell.getCellStyle();
CellStyle targetCellStyle = workbook.createCellStyle();
targetCellStyle.cloneStyleFrom(sourceCellStyle);
targetCell.setCellStyle(targetCellStyle);
// 复制值和图像
switch (sourceCell.getCellTypeEnum()) {
case STRING:
targetCell.setCellValue(sourceCell.getStringCellValue());
break;
case NUMERIC:
targetCell.setCellValue(sourceCell.getNumericCellValue());
break;
case BOOLEAN:
targetCell.setCellValue(sourceCell.getBooleanCellValue());
break;
case FORMULA:
// 如果单元格是公式,则复制公式本身
targetCell.setCellFormula(sourceCell.getCellFormula());
break;
case BLANK:
// target.setBlank();
break;
default:
// 默认处理
}
// 处理图像(如果存在)
if (source instanceof XSSFSheet && target instanceof XSSFSheet) {
XSSFSheet srcSheet = (XSSFSheet) source.getSheet();
XSSFSheet tgtSheet = (XSSFSheet) target.getSheet();
List<POIXMLDocumentPart> relations = srcSheet.getRelations();
for (POIXMLDocumentPart rel : relations) {
if (rel instanceof XSSFDrawing) {
XSSFDrawing srcDrawing = (XSSFDrawing) rel;
XSSFDrawing tgtDrawing = tgtSheet.createDrawingPatriarch();
List<XSSFShape> shapes = srcDrawing.getShapes();
for (XSSFShape shape : shapes) {
if (shape instanceof XSSFPicture) {
XSSFPicture srcPicture = (XSSFPicture) shape;
XSSFClientAnchor anchor = srcPicture.getClientAnchor();
XSSFClientAnchor newAnchor = new XSSFClientAnchor(
anchor.getDx1(), anchor.getDy1(), anchor.getDx2(), anchor.getDy2(),
targetCell.getColumnIndex(), target.getRowNum(), targetCell.getColumnIndex() + 1, target.getRowNum() + 1);
int pictureIndex = workbook.addPicture(srcPicture.getPictureData().getData(), Workbook.PICTURE_TYPE_PNG);
XSSFPicture tgtPicture = tgtDrawing.createPicture(newAnchor, pictureIndex);
tgtPicture.resize();
}
}
}
}
}
}
}
}
请注意,上述代码假设源文件和目标文件都是基于Apache POI库进行操作的。修改后的代码将复制行数据的同时复制图像,并根据目标单元格的位置调整图像位置。
