Imports Bytescout.PDFExtractor

' This example demonstrates the use of Optical Character Recognition (OCR) with "OCRMaximizeCPUUtilization" property to extract text
' from scanned PDF documents and raster images.

' To make OCR work you should add the following references to your project:
' "Bytescout.PDFExtractor.dll", "Bytescout.PDFExtractor.OCRExtension.dll".
