  • PPTXDocument: this class is used as an abstraction to represent one in-memory PowerPoint document file and it is derived from super class REDocument.
  • PPTXPage: this class is defined to display one PPT slide in Visual Basic .NET programming application.
  • ToImage(): as this VB.NET PowerPoint barcode reader control can only read barcode from image object, it will render source PPT slide to image object using ToImage method first.
  • Scan(): this barcode reading method will direct VB.NET PPT barcode scanner to detect barcode image(s) from scanning whole PPT slide.
  • ScanRegions(): if you just want to detect barcode image(s) from scanning defined slide area, please use this method to customize your VB.NET PPT barcode scanning process.
