將形狀添加到Excel工作表：

import com.spire.xls.*;
import com.spire.xls.core.*;
import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.File;

public class addShapestoExcel {
    public static void main(String[] args) throws Exception {

        String output = "output/AddShapesToExcelSheet.xlsx";

        //create a workbook.
        Workbook workbook = new Workbook();

        //get the first worksheet.
        Worksheet sheet = workbook.getWorksheets().get(0);

        //add a triangle shape.
        IPrstGeomShape triangle = sheet.getPrstGeomShapes().addPrstGeomShape(2, 2, 100, 100, PrstGeomShapeType.Triangle);
        //fill the triangle with solid color.
        triangle.getFill().setForeColor( Color.YELLOW);
        triangle.getFill().setFillType( ShapeFillType.SolidColor);

        //add a heart shape.
        IPrstGeomShape heart = sheet.getPrstGeomShapes().addPrstGeomShape(2, 5, 100, 100, PrstGeomShapeType.Heart);
        //fill the heart with gradient color.
        heart.getFill().setForeColor(Color.RED);
        heart.getFill().setFillType(ShapeFillType.Gradient);

        //add an arrow shape with default color.
        IPrstGeomShape arrow = sheet.getPrstGeomShapes().addPrstGeomShape(10, 2, 100, 100, PrstGeomShapeType.CurvedRightArrow);

        //add a cloud shape.
        IPrstGeomShape cloud = sheet.getPrstGeomShapes().addPrstGeomShape(10, 5, 100, 100, PrstGeomShapeType.Cloud);
        //fill the cloud with custom picture
        BufferedImage image = ImageIO.read(new File("SpireXls.png"));
        cloud.getFill().customPicture(image, "SpireXls.png");
        cloud.getFill().setFillType( ShapeFillType.Picture);

        //save to file.
        workbook.saveToFile(output, ExcelVersion.Version2013);
        }
}

輸出如下：

從Excel工作表中刪除特定形狀或所有形狀：

import com.spire.xls.*;

public class removeShape {
    public static void main(String[] args) throws Exception {

                 //Load the sample file
                Workbook workbook = new Workbook();
                workbook.loadFromFile("output/AddShapesToExcelSheet.xlsx");

                //get the first worksheet.
                Worksheet sheet = workbook.getWorksheets().get(0);

                //delete the second shape in the worksheet
                sheet.getPrstGeomShapes().get(1).remove();

              /* //delete all shapes in the worksheet
                for (int i = sheet.getPrstGeomShapes().getCount()-1; i >= 0; i--)
                 {
                   sheet.getPrstGeomShapes().get(i).remove();
                 }*/

                //save to file.
                workbook.saveToFile("output/RemoveParticularShape.xlsx", ExcelVersion.Version2013);
            }
        }
