Barcodescanner

This is an Android barcode scanning library designed to detect and decode barcode data from a live camera feed. It provides the core infrastructure for translating visual patterns into text on mobile devices.

The library includes a camera preview manager that adjusts aspect ratios and feed sizes to fit various screen dimensions, as well as a hardware controller for managing flash, autofocus, and sensor selection. It also features a barcode format filter to restrict scanning to specific barcode types to increase detection speed and accuracy.

The project covers camera hardware control, live barcode decoding, and user interface customization for designing tailored view finders and visual overlays.

Features

  • Camera Feed Decoders - Detects and decodes barcode data from a live camera feed by translating visual patterns into text.
  • Android Camera Barcode SDKs - Provides a comprehensive SDK for integrating real-time barcode scanning into Android applications via the device camera.
  • Android Barcode Scanner Libraries - Provides an Android library for detecting and decoding barcode data from a live camera feed.
  • Camera Capture Controllers - Handles low-level camera hardware control, including flash and autofocus, to optimize scanning image quality.
  • Flash and Focus Controls - Provides programmatic management of flash toggling and autofocus to optimize image capture for scanning.
  • Advanced Mobile Camera Controls - Manages camera sensors, autofocus, and flash settings on Android devices to optimize scanning image capture.
  • Hardware Abstraction Layers - Provides a consistent API for managing camera flash, autofocus, and sensor selection across different Android devices.
  • Preview Aspect Managers - Adjusts the aspect ratio and size of camera feeds to fit various Android screen dimensions.
  • Custom Viewfinder Designs - Creates tailored view finders and visual overlays to guide users during the barcode scanning process.
  • Aspect Ratio Correction - Adjusts camera preview dimensions to prevent image stretching and maintain correct proportions across different screen scales.
  • Camera Index Selections - Enables switching between available camera sensors on the device to source the scanning feed.
  • Event-Driven Callbacks - Triggers specific application actions immediately after a barcode is successfully decoded from the camera feed.
  • Viewfinder Overlays - Renders a customizable visual guide over the camera preview to assist users in aligning barcodes.
  • Camera Preview Embeddings - Manages the embedding and aspect ratio of the camera preview within the Android view hierarchy.
  • Preview Dimension Scaling - Adjusts preview size and aspect ratio tolerance to ensure the camera view fits various screen dimensions.
  • Custom View Rendering - Allows modifying the appearance and shape of the scanning overlay using custom visual attributes.
  • Barcode Format Filters - Restricts decoding to a specific subset of barcode formats to increase detection speed and accuracy.

    CameraView is a high-level Android camera library and hardware wrapper designed for capturing photos and videos. It provides an abstraction layer for managing camera hardware and a media capture API for recording high-resolution video and RAW photos with configurable bitrates and resolutions. The project features a real-time camera filter framework and a preview manager. These systems allow for the application of custom shaders and visual effects to live camera streams and the rendering of previews with customizable aspect ratios, overlays, and composition grids. The library covers a wide ra

    This is an Android library that adds barcode scanning to applications using the device camera. It wraps the ZXing barcode decoding engine and exposes it through a simplified Android API, functioning as a software development kit for real-time scanning. The library offers two primary integration approaches: launching a full-screen camera activity through Android intents, or embedding a live scanner view directly into application layouts using SurfaceView or TextureView. Scanner behavior can be customized through programmatic configuration objects before scanning begins, and scanned barcode dat

    This is a ZXing-based toolkit for integrating barcode and QR code scanning and generation into Android applications. It functions as a barcode scanner capable of decoding data from both live camera streams and static image files. The library includes a QR code generator that supports the creation of image files with custom logos embedded in the center of the code. It also provides a customizable camera scanning interface, allowing for adjustments to the scanning overlay and control over the device flash to improve visibility in low light. Its broader capabilities cover the extraction of text
