C#绘制条码CODE39和CODE39全码模式

不使用字体来绘制CODE39码

效果图

使用

1. MyImage.BandCode.Code39_Code39= new MyImage.BandCode.Code39();
3. _Code39.Height=120;
4. _Code39.Magnify=1;
5. _Code39.ViewFont= new Font( "宋体" ,20);
6. pictureBox1.Image=_Code39.GetCodeImage( "123ABC4567890" ,MyImage.BandCode.Code39.Code39Model.Code39Normal, true );
7. pictureBox1.Image.Save(@ "C:/1.bmp" );
