如何在 VB ASP.NET 中生成像素优化的 PDF417？

请将以下代码插入 Page_Load 事件

  Me.BarcodeControl1.Barcode.BarcodeType = BarcodeType.Pdf417
  Me.BarcodeControl1.Barcode.Data = data

  ' TBarCode V7, V8:
  Dim horizModules As Integer
  Dim verticRows As Integer

  horizModules = Me.BarcodeControl1.Barcode.CalculateXColumnsOf2DBarcode()
  verticRows = Me.BarcodeControl1.Barcode.CalculateNumberOfRows()

  Me.BarcodeControl1.Barcode.SizeMode =  SizeMode.FitToBoundingRectangle
  ' for the dpi use at least 3 times the screen resolution (or >= 300 dpi)
  Me.BarcodeControl1.Barcode.Dpi = 96 * 3
  Me.BarcodeControl1.Width = New Unit(horizModules)
  ' for the height use a multiplier of 3 - 5
  Me.BarcodeControl1.Height = New Unit(verticRows * 5)

End Sub
