Here’s some C code that shows how to read an opencv cv::Mat image using the barcode reader toolkit. The main points to note are: Read the image using the cv::IMREAD_GRAYSCALE flag Flip the image vertically Align the scan lines to 4 byte boundaries #include <barcode.h> #include <iostream> #include <opencv2/core/core.hpp> #include <opencv2/highgui/highgui.hpp> #include <opencv2/imgproc/imgproc.hpp> static void

A barcode font is a quick and easy way to create a barcode and a lot cheaper than buying software to create the barcode, so what could be wrong in using a Code128 font? A Code 128 barcode breaks down as follows: Start character Data characters Checksum character Stop character The start and stop characters
We’ve made some changes to BardecodeFiler to improve speed when handling very large batches: 2 new options have been added under Options/Log Files/Enable Disable: Hide file details in tree until end of batch – do not display details for each file processed in a batch until the batch has completed. Clear tree data at start
The Natural History Museum in London is currently digitizing its collection, including insect slides with barcodes. BardecodeFiler is used to read the barcode from a photo of the slide and rename the photo to the code for the specimen. Here’s a link to video that explains the whole process: https://www.wired.co.uk/video/how-the-natural-history-museum-is-scanning-80-million-dead-creatures Here’s another link to an
We’re pleased to announce the release of BardecodeFiler version 18.104.22.168. The main highlight of this release is the new way of presenting information in the main output window.

We’re pleased to announce that version 22.214.171.124 of the Windows barcode reader SDK has been released. This version has significant speed improvements to datamatrix recognition and enhanced support for datamatrix barcodes printed in a dotted pattern. Here’s the full list of changes: Fix for random barcode coordinates when MultipleRead is not enabled. Fix for false
Here’s an interesting article on how it’s possible to fool technology designed to keep an eye on us all. In this case it’s number plate recognition but similar problems can occur with barcode recognition – random artefacts in an image can resemble the patterns created by barcodes. Fortunately it’s easier to distinguish the false positive
Version 126.96.36.199 of our barcode reader SDK for Windows has been released. This should be of particular interest to developers using Chinese characters in QR Codes and anyone reading PDF417 barcodes. 1. Performance improvement for images with certain types of repeated pattern. 2. Fix for recognition of Kanji characters using the Kanji byte compaction scheme
BardecodeFiler Version 188.8.131.52 has been released. This version processes large files in the desktop interface much faster. For example, a 6000 page PDF file should process at at least 2X the speed of version 2.4.
