Different utilities generate different-looking barcode symbols #93

hi, I wanted to use postscriptbarcode to create qrcode. I have always used the program on the web "https://keremerkan.net/qr-code-and-2d-code-generator". But I saw that the design of the generated code is different from the one generated by postscriptbarcode. An example: "http://inforsrl.net/skillrow/rower?et=RWX18006000XAB" is very different. I used the same level = H. Are there any other options to make it the same? Thank you |

2D symbologies such as QR Code provide a range of different encoding modes that are optimal for different types of data. It is possible to switch between modes to encode different components of the input optimally, and there is freedom of choice for implementations in how to achieve this. Some encoders strive harder than others to optimise the data compaction. BWIPP should be maximally efficient and therefore tends to generate smaller symbols that some other encoders. Perhaps this is what you are seeing? Despite appearing different the symbols should be read identically. A typical scanner does not communicate symbol metrics, only data payload, to the host over a basic channel such as keyboard wedge or USB emulation. If you require a metrically-compatible symbol with a stable size for design purposes then you can fix the size of the symbol using the |
