Since the image and the recognized text are isolated, a PDF library only needs to extract the page image layer and pass it to a barcode engine for processing.

Image-over-Text PDFs are also referred to as searchable PDFs. A mapping is created for each word from the OCR text to the zone from which the text was located on the scanned image. When running an image-only PDF file through an OCR engine, the recognized text is embedded behind the scanned image of a document. Scanning barcodes and QR codes from scanned PDFs is not too different from scanning from images, except that the PDF library needs to separate the pages into individual images. This is why they are sometimes referred to as scanned PDFs. Image-only PDFs are mostly generated from MFPs, scanners, and camera captures. Note: The ‘PDFRM_RASTER’ mode works for all barcode formats, including linear barcode, PDF417, QR code, and other 2D codes. Conversely, a small ‘PDFRasterDPI’ renders a small image where the barcode region may be distorted. A large ‘PDFRasterDPI’ value renders a large image and slows down the processing speed. The tricky part is to choose the appropriate value of ‘PDFRasterDPI’ for rendering the image. Settings.PDFReadingMode = EnumPDFReadingMode.PDFRM_RASTER Refer to the code snippet below.Ĭ# Code snippet (barcode format pdf page pdf reading mode PDFRasterDPI )ĭ settings = reader.GetRuntimeSettings() We set the parameter ‘ PDFReadingMode’ as ‘PDFRM_RASTER’. Render each page of the PDF as an imageĪnother option is to render the page as a full-page image.

To get the best result in all 3 types of files, Dynamsoft Barcode Reader comes with a customizable parameter ‘ PDFReadingMode’ which can be used to set how to render PDF files. They are created using OCR to recognize the text in image-only PDFs.ĭynamsoft Barcode Reader comes with a PDF library embedded. These are mostly from scanned documents or snapshots from cameras.

They are created using software such as Microsoft® Word®, Excel® or via the “print” function within a software application (virtual printer). In this article, we will explore how the industry’s best barcode SDK decodes a QR code in different types of PDFs.īased on how PDF files are created, PDFs can be roughly divided into 3 categories: So, as long as the QR codes are clearly captured, a near 100% accuracy in form-based data capture is achievable.

QR Codes are generated with error correction. The QR code enclosed within the PDF file can be decoded to reveal the complete user-supplied data on the form. The recipient would simply capture the documents via a traditional scanner or a camera and save as a PDF file. It would encode all the information that a user enters when the form is filled. A QR Code can be embedded in the paper-based form.

QR Code has been proven to streamline manual processes and improve efficiency. However, it still requires some human supervision to ensure the data capture process is done correctly. Optical Character Recognition (OCR) can help reduce the amount of human involvement. Re-keyed-paper-based-form data not only is human-intensive, it’s also error-prone.

Accurately capturing data from paper forms can be extremely challenging.
