Rohan Ahmed · Answer

If you want to detect the barcode location in the PDF file automatically then crop the barcode portion and save it as image you might need to use a programming toolkit (leadtools) that supports barcode recognition features. Also they have image processing functions (including Crop) that can be added to a new image and saved to any supported image format. You can find more details in this article: http://www.codeproject.com/Articles/278301/How-to-Read-Barcodes-from-Images-using-LEADTOOLS
