import com.spire.xls.core.ITextBoxLinkShape;

import java.awt.*;

public class AddTextBox {
    public static void main(String[] args) {
        //创建实例
        Workbook wb = new Workbook();

        //获取工作表
        Worksheet sheet = wb.getWorksheets().get(0);

        //添加文本框1

        textBox1.setText("添加文本到文本框");//添加文本到文本框
        ((ITextBoxLinkShape) textBox1).getFill().setFillType(ShapeFillType.SolidColor);//设置文本框填充类型

        textBox1.setHAlignment(CommentHAlignType.Center);//设置文本对齐方式
        textBox1.setVAlignment(CommentVAlignType.Center);
        textBox1.setTextRotation(TextRotationType.TopToBottom);//设置文本方向
        ((ITextBoxLinkShape) textBox1).setVisible(true);//设置文本框可见
        ((ITextBoxLinkShape) textBox1).setName("文本框1");//设置文本框名称

        //添加文本框2
        ITextBox textBox2 = sheet.getTextBoxes().addTextBox(7,10,120,300);//指定文本框位置、大小

import java.io.File;
import java.io.IOException;

public class ReadTextBox {
    public static void main(String[] args) throws IOException {
        //创建实例，并加载测试文档
        Workbook wb = new Workbook();
        wb.loadFromFile("AddTextBox.xlsx");

        //获取工作表
        Worksheet sheet = wb.getWorksheets().get(0);

        //获取第一个文本框，读取文本及填充色
        XlsTextBoxShape textBoxShape1 = (XlsTextBoxShape) sheet.getTextBoxes().get(0);
        String  text = textBoxShape1.getText();
        Color color = textBoxShape1.getFillColor();
        String  name = textBoxShape1.getName();
        System.out.println("文本内容："+ text + " 填充色：" + color + " 名称："+ name);

        //获取第一个文本框，读取填充图片
        XlsTextBoxShape textBoxShape2 = (XlsTextBoxShape) sheet.getTextBoxes().get(1);
        BufferedImage image = textBoxShape2.getFill().getPicture();
        ImageIO.write(image,"png", new File("ExtractedImg.png"));
    }
}

        Workbook wb = new Workbook();
        wb.loadFromFile("AddTextBox.xlsx");

        //获取工作表
        Worksheet sheet = wb.getWorksheets().get(0);

        //获取文本框，删除
        XlsTextBoxShape textBoxShape = (XlsTextBoxShape) sheet.getTextBoxes().get(0);
        textBoxShape.remove();

        //保存文档
        wb.saveToFile("RemoveTextBox.xlsx",FileFormat.Version2013);
