DicomViewer class
A production-ready, interactive widget for high-performance DICOM rendering.
DicomViewer provides a seamless user experience by integrating:
- GPU-Accelerated Rendering: Uses the DicomShaderPainter for clinical precision.
- Interactive Gestures: Built-in support for Panning, Zooming, and dragging to adjust Windowing (Contrast/Brightness).
- State Management: Listens to a DicomController to automatically update itself when metadata or pixel data changes.
Default Interactions:
- Two-Finger Pinch: Zoom in/out.
- Single-Finger Drag: Adjust Window Level/Width.
- Double-Tap: Reset contrast/brightness to DICOM defaults.
