Here is an example that demonstrates how to convert a text file to a PDF document.

VB.NET

    ' get text of text file
    Dim text As String = System.IO.File.ReadAllText(sourceTextFilename, System.Text.Encoding.UTF8)

    ' create PDF document
    Using pdfDocument As New Vintasoft.Imaging.Pdf.PdfDocument(destPdfFilename, Vintasoft.Imaging.Pdf.PdfFormat.Pdf_14)
