Add real-world implementation example of click-to-zoom feature to maintainer documentation:
**IMPLEMENTATION_GUIDE.md:**
- Complete step-by-step implementation guide showing how click-to-zoom was added
- Explains each component (input signals, IvyPinch method, template, CSS)
- Includes code snippets from actual implementation
- Shows real-world usage for anomaly detection use case
- Provides testing checklist
**docs/README.md:**
- Added click-to-zoom to "Where do I find...?" quick reference table
- Added to "How do I...?" task guide
- Helps maintainers quickly locate click-to-zoom documentation
This serves as a template for future feature additions and helps maintainers understand how to add similar interactive features to the library.
Implement click-to-zoom feature perfect for anomaly detection and defect inspection workflows:
**New Input Signals:**
- enableClickToZoom: Enable/disable click-to-zoom (default: false)
- clickToZoomScale: Target zoom scale when clicking (default: 2.5)
**Implementation:**
- Click any point on image to zoom to that exact location
- Click again to zoom out back to original view
- Cursor changes to zoom-in icon when feature is enabled
- Smooth animated transitions
- Respects zoom limits (min/max scale)
- Works alongside existing touch/pinch zoom
**Use Cases:**
- Anomaly detection: Click suspicious areas to examine closely
- Defect inspection: Quickly zoom to specific spots
- Detail review: Fast workflow for inspecting multiple points
**Technical Details:**
- Added IvyPinch.zoomToPoint(clientX, clientY, targetScale) method
- Calculates click position relative to element bounds
- Applies zoom transform centered on clicked point
- Component wrapper method handles event and configuration
- CSS cursor feedback for better UX
Updated documentation with usage examples and testing scenarios.
Document the new brightness control feature across all documentation:
- Update README.md with brightness examples and API documentation
- Add brightness control to QUICK_REFERENCE.md signal architecture
- Include brightness in testing scenarios and configuration tests
- Document new input signals: enableBrightnessControl, brightnessStep, minBrightness, maxBrightness
- Document new output signal: brightnessChanged
- Document new methods: brightnessIn(), brightnessOut(), resetBrightness()
- Document new computed signals: brightness(), isBrightnessControl(), isBrightnessAtMin(), isBrightnessAtMax()
- Add CSS filter effects pattern example to QUICK_REFERENCE.md
Added complete documentation suite for library maintainers:
