Question
DocumentOCR - ProcessToText method output
I am trying to process a text from scanned receipt using DocumentOcr's ProcessToText method. The method returns a string containing two whitespaces(apart from linespace) - \u2028 and u\2029 that should help format the string to match formatting of the scanned file. However, I cannot figure out how that can be achieved and the method seems to be processing different parts of the image at random - not by lines, not by columns, not by some kind of parts.
Attached is one example of the input for the method(test_ocr.jpg) along with a text file with output(output.txt) - new line and the ";" are the different whitespaces. As you can see, there seems to be no apparent order in which the method processes the text.
Is there a way to format the processed data to recreate (at least) relative positions of text from the original image?
Same flow is not working for me. It always return the false value. please help with this.
Hello Jacub,
Unfortunately, this random parsing is a limitation of Abbyy OCR engine in cases like this (crumpled paper, tilted text, low resolution).
Try to use ProcesstoPdf method instead. It reads an image as a one piece of text and puts it in PDF as is. Then you can use PdfConnector and parse the text from pdf as you like. Some info on these methods: http://help.openspan.com/80/Components/DocumentOCR_Component.htm#ProcessToPdf and http://help.openspan.com/80/Components/PDFConnector_Component_Properties,_Methods,_and_Events.htm
