The central bull's-eye is 9×9 or 13×13 pixels, and one row of pixels around that encodes basic coding parameters, producing a "core" of 11×11 or 15×15 squares. Data is added in "layers", each one containing two rings of pixels, giving total sizes of 15×15, 19×19, 23×23, etc.
An example of a High Capacity Color Barcode: a Microsoft Tag referring to the HCCB article on the English Wikipedia. High Capacity Color Barcode (HCCB) is a technology developed by Microsoft for encoding data in a 2D "barcode" using clusters of colored triangles instead of the square pixels conventionally associated with 2D barcodes or QR codes.

Python Bar Code 128 – This code appears to draw boxes one pixel wide. It appears it was modified from a short line long line bar code which would have drawn lines. The "Black boxes" should be the same size as the "White Boxes". GenCode128 – Free C# source code implementation of Code128. Almost all features are implemented, but is not 100% ...
MaxiCode is a public domain, machine-readable symbol system originally created by the United Parcel Service (UPS) in 1992. [1] Suitable for tracking and managing the shipment of packages, it resembles an Aztec Code or QR code, but uses dots arranged in a hexagonal grid instead of square grid. MaxiCode has been standardised under ISO/IEC 16023. [2]
Barcode library or Barcode SDK is a software library that can be used to add barcode features to desktop, web, mobile or embedded applications. Barcode library presents sets of subroutines or objects which allow to create barcode images and put them on surfaces or recognize machine-encoded text / data from scanned or captured by camera images with embedded barcodes.
GS1 introduced the barcode in 1974. [8] A barcode encodes a product identification number that can be scanned electronically, making it easier for products to be tracked, processed, and stored. Barcodes improve the efficiency, safety, speed and visibility of supply chains across physical and digital channels.
C2: Marker for the center of the barcode. 6 digits in the left group: 003994. 6 digits in the right group (the last digit is the check digit): 155486. A digit is encoded in seven areas, by two black bars and two white spaces. Each black bar or white space can have a width between 1 and 4 areas.
The presentation of the Check Digit both electronically and in printed form on the label and packaging is very important. Logistics (using bar-code reader) and EIR/CEIR administration cannot use the Check Digit unless it is printed outside of the packaging, and on the ME IMEI/Type Accreditation label.
