Tapirscan is a browser-based interactive demo focused on barcode scanning, with particular attention to barcodes rotated at different angles. It positions itself as a comparison environment where the Tapirscan scanner is evaluated alongside independent readers such as ZXing and ZBar, helping visitors see how different engines behave on the same input.
The core of the site is a side-by-side comparison. Each selected scanner analyzes identical image pixels, and colored outlines mark detected barcode locations with labels showing decoded values and which scanners found them. Tapirscan itself offers four scanning effort levels—TS-Low, TS-Med, TS-High and TS-VHigh—trading speed against detection effort. Additional scanners include Quagga2 for linear barcodes, ZXing-JS with optional extra search passes, jsQR for QR codes and the native BarcodeDetector where supported.
Input options are flexible: visitors can pick a demo image, load their own photo or PDF, or use a webcam or phone camera. Images can be rotated and zoomed for closer inspection. Result cards report decoded values and processing times, making it easy to compare accuracy and speed across configurations.
This site is aimed at developers and technical users who need to choose or benchmark a barcode scanning library, especially for challenging cases like rotated codes. It is an exploratory demo rather than a comprehensive benchmark, so results on individual images should be treated as indicative rather than definitive.
