提取MS字表单元格作为图像？

Question

  public static void readTablesDataInDocx(XWPFDocument doc) {
    int tableIdx = 1;
    int rowIdx = 1;
    int colIdx = 1;
    List table = doc.getTables();
    System.out.println("==========No Of Tables in Document=============================================" + table.size());
    for (int k = 0; k < table.size(); k++) {
        XWPFTable xwpfTable = (XWPFTable) table.get(k);
        System.out.println("================table -" + tableIdx + "===Data==");
        rowIdx = 1;
        List row = xwpfTable.getRows();
        for (int j = 0; j < row.size(); j++) {
            XWPFTableRow xwpfTableRow = (XWPFTableRow) row.get(j);
            System.out.println("Row -" + rowIdx);
            colIdx = 1;
            List cell = xwpfTableRow.getTableCells();
            for (int i = 0; i < cell.size(); i++) {
                XWPFTableCell xwpfTableCell = (XWPFTableCell) cell.get(i);
                if (xwpfTableCell != null) {
                    System.out.print("\t" + colIdx + "- column value: " + xwpfTableCell.getText());
                }
                colIdx++;
            }
            System.out.println("");
            rowIdx++;
        }
        tableIdx++;
        System.out.println("");
    }
}

System.out.print("\t" + colIdx + "- column value: " + xwpfTableCell.getText());

当您有一个单元格时，您可以获得形成该单元格的段落。这些段落依次由运行形成，您可以通过调用getruns方法获得运行。运行本身可以包含嵌入的图像，您可以通过调用GetEmbeddedPictures方法获得这些图像。

因此，您可以使用一个方法来获取单元格的嵌入图片：

public static void printDescriptionOfImagesInCell(XWPFTableCell cell) {
    List<XWPFParagraph> paragrahs = cell.getParagraphs();
    for (XWPFParagraph paragraph : paragraphs) {
        List<XWPFRun> runs = paragraph.getRuns();
        for (XWPFRun run : runs) {
            List<XWPFPicture> pictures = run.getEmbeddedPictures();
            for (XWPFPicture picture : pictures) {
                //Do anything you want with the picture:
                System.out.println("Picture: " + picture.getDescription());
            }
        }
    }
}

您应该能够通过图片文档发现关于实际图片的更多信息，并更改方法以实际获取图像数据、名称等。
