.net 導出帶條碼的PDF

1. Nuget添加引用：ZXing.Net生成條形碼，ZXing.Net.Bindings.ImageSharp生成圖片
2. 將圖片流插入單元格

舉個栗子：

BarcodeWriter writer = new BarcodeWriter();
writer.Format = BarcodeFormat.CODE_128;
writer.Options = new ZXing.Common.EncodingOptions
{
Height = 40,
Width = 200,
PureBarcode = true
};
MemoryStream stream = new MemoryStream();

using (var image = writer.Write("條碼字符"))
{
image.Save(stream, System.Drawing.Imaging.ImageFormat.Bmp);
}
Aspose.Cells.Drawing.PictureCollection pictures = sheet.Pictures;
pictures.Add(0, 12, stream);
