I think that jshand2010 wanted to ask if there is a package or unit that converts a barcode in form of an image file to numbers or text, i.e. a software solution in Free Pascal.
Of course, most barcode scanners are recognized as keyboards, but obviously that wasn't what jshand2010 was searching for. Likewise, these Excel barcode add-ins create barcodes from numbers or strings, but the question was for the oppositve conversion.
