Profiles - VB.NET

PDF Extractor SDK sample in VB.NET demonstrating ‘Profiles’

Program.vb
Imports Bytescout.PDFExtractor

' This example demonstrates the use of profiles. Profiles are set of properties 
' allowing to apply them to Extractor in any combination quickly. You can use 
' predefined profiles or create you own in JSON format like in this example.

Class Program

    Friend Shared Sub Main(args As String())

        ' Create Bytescout.PDFExtractor.TextExtractor instance
        Dim extractor As New TextExtractor()
        extractor.RegistrationName = "demo"

        extractor.OCRLanguageDataFolder = "c:\Program Files\Bytescout PDF Extractor SDK\ocrdata_best"

        ' Load sample PDF document
        extractor.LoadDocumentFromFile("sample_ocr.pdf")

        ' Apply predefined profiles
        extractor.Profiles = "ocr, newspaper-layout"
        ' Extract text to file
        extractor.SaveTextToFile("result1.txt")


        extractor.Reset()
