C#绘制条码CODE39和CODE39全码模式
使用
- MyImage.BandCode.Code39 _Code39 = new MyImage.BandCode.Code39();
- _Code39.Height = 120;
- _Code39.Magnify = 1;
- _Code39.ViewFont = new Font("宋体", 20);
- pictureBox1.Image = _Code39.GetCodeImage("123ABC4567890", MyImage.BandCode.Code39.Code39Model.Code39Normal, true);
- pictureBox1.Image.Save(@"C:\1.bmp");
