Data Matrix Code web image analysis
After I decoded a lot of QR Code images, it was an easy step to download Data Matrix Code images and find out, what kind of content people encode in these. For those, who are interested, for the decoding, I used the libdmtx library. As a backup, I used other libraries to check, if the code was really a Data Matrix or if the content of the image contained other types of codes. Therefore in some cases, I found QRcodes and 1D Barcodes, which is effected by the results of the image search engines.
