Open Source C Barcode Scanners

A comprehensive software suite for reading barcodes. Supports EAN/UPC, Code 128, Code 39, Interleaved 2 of 5 and QR Code. Includes libraries and applications for decoding captured barcode images and using a video device (eg, webcam) as a barcode scanner.

ZBar is an open source software suite for reading bar codes from various sources, including webcams. As its development stopped in 2012, I took the task of keeping it updated with the V4L2 API. This is the main repository for it. A library for reading barcodes from various sources, useful for applications needing barcode scanning.

This is a driver for reading from an USB barcode reader.

Here is a c_version of Thomas Bleeker's pnglib 1.0, a free graphy library. His site is https://www.madwizard.org/programming/projects/pnglib Thomas's original code is x86-asm. She(the code) can read and display PNG images in programs, and link without Zlib. With the author's permission, Leisure bamboo translate her to c. So she can be compile by turbo c 2.0, borland c 4.5, visual c 6.0, keil c51 7.5, or others. Some(not all) plainform where she can run, as below: 1)dosbox, see about her in sample.tc2. dpmi.bc4; 2)window, see about her in sample.bc4, dpmi.bc4, sample.vc6; 3)c51's uv2 simulator, see about her in sample.uv2; 4)arm singlechip, that is cino f780 barcode scanner. She can decompress apng(Animated PNG) now, There are some demo file 01.png, 04.png ... 32.png in root folder. She is small(12k for vc6, 32bit code; 21k for bc4, 32bit code; 27k for tc2, 16bit code) and beautiful.

Generate QR codes, scan QR codes, and identify QR codes for pictures. The modification range is large, and there is no plan to submit a PR for the barcodescanner library. Various scan frames can be customized. Customizable full-screen scan or only recognize the code within the scan frame area. The format of the code to be recognized can be customized (see the onClick method in TestScanActivity for detailed usage). Can control the flash, convenient to use at night. Can be set to scan with the front camera. Two-finger zoom preview. Can monitor the ambient brightness and prompt the user to turn on and off the flash. Automatically zoom in when a smaller code is recognized. ZXing generates a QR code with customizable color and logo. ZXing generates one-dimensional codes. ZXing scan barcode, QR code. ZXing recognizes barcode and QR code images in the gallery.

XMMS Jukebox Component. The jukebox that lets you pick the next N songs, and plays them. Then switches back to random mode playing. Eventually I would like to also track the most requested songs etc, as well as be driven by a barcode reader.
