# Camera Implementation Documentation |
|||
|
|||
## Overview |
|||
|
|||
This document describes how camera functionality is implemented across the TimeSafari application. The application uses cameras for two main purposes: |
|||
|
|||
1. QR Code scanning |
|||
2. Photo capture |
|||
|
|||
## Components |
|||
|
|||
### QRScannerDialog.vue |
|||
|
|||
Primary component for QR code scanning in web browsers. |
|||
|
|||
**Key Features:** |
|||
|
|||
- Uses `qrcode-stream` for web-based QR scanning |
|||
- Supports both front and back cameras |
|||
- Provides real-time camera status feedback |
|||
- Implements error handling with user-friendly messages |
|||
- Includes camera switching functionality |
|||
|
|||
**Camera Access Flow:** |
|||
|
|||
1. Checks for camera API availability |
|||
2. Enumerates available video devices |
|||
3. Requests camera permissions |
|||
4. Initializes camera stream with preferred settings |
|||
5. Handles various error conditions with specific messages |
|||
|
|||
### PhotoDialog.vue |
|||
|
|||
Component for photo capture and selection. |
|||
|
|||
**Key Features:** |
|||
|
|||
- Cross-platform photo capture interface |
|||
- Image cropping capabilities |
|||
- File selection fallback |
|||
- Unified interface for different platforms |
|||
|
|||

|||
|
|||
### Platform Services |
|||
|
|||

|||
|
|||
**Camera Capabilities:** |
|||
|
|||
- Uses HTML5 file input with capture attribute |
|||
- Falls back to file selection if camera unavailable |
|||
- Processes captured images for consistent format |
|||
|
|||
#### CapacitorPlatformService |
|||
|
|||

|||
|
|||
**Status:** |
|||
|
|||
- Camera functionality not yet implemented |
|||
- Planned to use Electron's media APIs |
|||
|
|||
## Platform-Specific Considerations |
|||
|
|||

|||
- Implements proper permission handling |
|||
|
|||
### Android |
|||
|
|||

|||
- Handles permission requests through Capacitor |
|||
|
|||
### Web |
|||
|
|||
