ZBar is an open-source C barcode reading library with C++, Python, [2] Perl, and Ruby bindings. [3] [4] [5] It is also implemented on Linux and Microsoft Windows as a command-line application, [6] and as an iPhone application.
The Postal Alpha Numeric Encoding Technique (PLANET) barcode was used by the United States Postal Service to identify and track pieces of mail during delivery – the Post Office's "CONFIRM" services. It was fully superseded by Intelligent Mail Barcode by January 28, 2013.
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.
The Barcode Scanner can automatically search the Web to identify a product with a barcode and use, for example, price-comparison information between vendors. The application can decode several 2D barcodes including the widely used QR Code and Data Matrix. QR codes are often embedded in websites; Barcode Scanner can open a browser at the encoded ...
The four types of symbols in an Intelligent Mail barcode. The Intelligent Mail barcode is a height-modulated barcode that encodes up to 31 decimal digits of mail-piece data into 65 vertical bars. [2] The code is made up of four distinct symbols, which is why it was once referred to as the 4-State Customer Barcode.
Possible corner finder patterns [2]: 6.3.8 on top-right and bottom-left barcode corners. Main finder pattern is used to detect the barcode on image and its corruption can make barcode unrecognizable. Finder pattern has vertical and horizontal size 1-1-3-1-1. Finder sub pattern helps to detect bottom-right corner of the barcode.
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% ...
The barcode scheme does not contain a check digit (in contrast to—for instance—Code 128), but it can be considered self-checking on the grounds that a single erroneously interpreted bar cannot generate another valid character. Possibly the most serious drawback of Code 39 is its low data density: It requires more space to encode data in ...
