Changelog | Web Document Scanner

Version 5.1.3 (16 August 2024)​

  • 🐞 Bug fixes:
    • Fixed a camera API quirk in the RTU UI Barcode Scanner component that resulted in a crash in Firefox

Version 5.1.2 (7 August 2024)​

  • 🐞 Bug fixes:
    • Fixes a bug where enabling multi-threading caused a significant slow-down for live-scanners, especially at high resolutions

Version 5.1.1 (10 June 2024)​

  • 🐞 Bug fixes:
    • Fixes a bug where the document outline in the cropping view is not correctly updated
    • Fixes a bug where the RTU UI Barcode Scanner would not scan well if multiple barcodes are visible in the same frame

Version 5.1.0 (31 May 2024)​

  • 🎉 New
    • Introduced a new Ready-To-Use Barcode Scanner UI.
    • Support of new barcode type MICRO_PDF_417.
    • AAMVA Title Document Parser.
    • Added more options to the text data scanner: validationPattern, matchSubstring and allowedCharacters.
  • 🚀 Improvements
    • Large performance increase thanks to improved multi-threading.
    • WASM loading & camera opening now happen in parallel, resulting in a reduced time-to-scan. If WASM is still loading when the camera is already opened, a spinner is shown.
    • WASM and JS files will now be requested with an additional cache-busting query parameter to ensure the latest version is always used. E.g., instead of ScanbotSDK.Asm.wasm, the file will now be requested as ScanbotSDK.Asm.wasm?5.1.0. This behavior can be configured or disabled using the requestSuffix config option during SDK initialization.
    • ImageProcessor: JPEG reading and writing is substantially faster thanks to multithreading.
    • Error and Erasure Correction to improve PDF_417, MICRO_PDF_417, and GS1_COMPOSITE.
    • Image filters: Antialiasing now requires significantly less memory.
    • Trimmed frames of MSI_PLESSEY, ITF, and CODABAR were likely scanned as false positives since the quiet zone requirement was not appropriately handled. Now, in live mode, we require a certain distance to the boundary and an additional quiet zone check.
    • Revamped ViewFinder with new styling options, including cornered or stroked style, strokeColor and -Width and configurable cornerRadius.
  • ⚠️ Breaking changes:
    • Barcode.parsedText is now called Barcode.parsedDocument and has a slightly different structure.
    • Removed deprecated ViewFinder left, right, top, widthProportion properties.
    • Support for jsdelivr CDN has been deprecated and will be removed in one of the next versions. Please host the SDK files on your own server or use a CDN of your own.
    • A workaround for certain webpack configurations (most notably that of create-react-app) has been removed. If you run into webpack errors when importing from scanbot-web-sdk/webpack, please switch to importing directly from scanbot-web-sdk and handle the hosting of the WASM files manually.
    • Multi-threading now requires the HTTP header Cross-Origin-Resource-Policy of value cross-origin to be set for the bundle/bin/*/*.js files. Before, a value of same-origin was also acceptable for that header.

Version 5.0.1 (30 Apr 2024)​
