' By default, "SearchablePDFMaker" uses one of the standard PDF fonts to apply 
' recognized text over the scanned document. Such fonts contain only basic characters 
' from ISO-8859-1 charset. 
' If you run OCR for one of the languages with characters that are not present in the default
' encoding, you should explicitly specify the font that contains the required characters
' using ".LabelingFont" property.
' If you run the application in Windows with a selected locale that matches OCR language, 
' it will be enough to specify the usual font "Arial". But if your app will run in an unknown
' environment (for example, in some virtual machine) you will need to install some full Unicode 
' font (e.g. "Arial Unicode MS") and then use it with SearchablePDFMaker:
' 
' searchablePDFMaker.LabelingFont = "Arial Unicode MS";

' Create Bytescout.PDFExtractor.SearchablePDFMaker object
Set searchablePDFMaker = CreateObject("Bytescout.PDFExtractor.SearchablePDFMaker")
searchablePDFMaker.RegistrationName = "demo"
searchablePDFMaker.RegistrationKey = "demo"

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

' Set the location of OCR language data files
searchablePDFMaker.OCRLanguageDataFolder = "c:\Program Files\Bytescout PDF Extractor SDK\ocrdata_best"
			
' Set OCR language
' "eng" for english, "deu" for German, "fra" for French, "spa" for Spanish etc - according to files in "ocrdata" folder.
searchablePDFMaker.OCRLanguage = "eng"  
' Find more language files at https://github.com/bytescout/ocrdata

' Set PDF document rendering resolution
searchablePDFMaker.OCRResolution = 300
