HSSFSimpleShape用于在电子表格中绘制形状。此类提供了一种方法 setShapeType()，该方法有助于绘制各种形状，例如椭圆形，直线形，矩形等。
让无涯教程来看一个例子。
Apache POI绘制形状示例
package poiexample; import java.io.FileOutputStream; import java.io.OutputStream; import org.apache.poi.hssf.usermodel.HSSFClientAnchor; import org.apache.poi.hssf.usermodel.HSSFPatriarch; import org.apache.poi.hssf.usermodel.HSSFSimpleShape; import org.apache.poi.hssf.usermodel.HSSFWorkbook; import org.apache.poi.ss.usermodel.Cell; import org.apache.poi.ss.usermodel.Row; import org.apache.poi.ss.usermodel.Sheet; import org.apache.poi.ss.usermodel.Workbook; public class ShapeExample { public static void main(String[] args) {Workbook wb = new HSSFWorkbook(); try (OutputStream os = new FileOutputStream("Learnfk.xls")) { Sheet sheet = wb.createSheet("Sheet"); Row row = sheet.createRow(4);//创建行 Cell cell = row.createCell(1);//创建一个单元格 HSSFPatriarch patriarch = (HSSFPatriarch) sheet.createDrawingPatriarch(); HSSFClientAnchor a = new HSSFClientAnchor( 0, 0, 1023, 255, (short) 1, 0, (short) 1, 0 ); HSSFSimpleShape shape = patriarch.createSimpleShape(a); shape.setShapeType(HSSFSimpleShape.OBJECT_TYPE_OVAL); wb.write(os); }catch(Exception e) { System.out.println(e.getMessage()); } } }
输出:
