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 2.6.1.1. The main highlight of this release is the new way of presenting information in the main output window. Gone is the free format text output, replaced by a tree structure that allows the user to explore the results from a batch and review previous batches
We’re pleased to announce that version 8.3.3.5 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
The Softek Barcode Reader SDK and our BardecodeFiler Windows application both use ‘regex’ pattern matching for matching barcode values. We often get asked advice on how to build a regex so we thought a short guide to the basics might be useful. Here is a simple example: ^\d{5}$ So let’s break it down: ^
The following script can be used for barcode testing on Linux in a similar way to the test option in SoftekSDKDemo (using the same options): echo “Test only with supplied options” r=`./bardecode $*` if test -n “$r” then echo “Found barcode: $r” exit fi echo “Test: Small quiet zones around barcodes (-q 10)” r=`./bardecode -q
