NCCamera Class Reference

Class describing position of the camera. More...

#include <com/navigine/idl/objc/NCCamera.h>

Inherits NSObject.

Instance Methods
(nonnull instancetype)	- initWithPoint:zoom:rotation:tilt:
	Default constructor for class NCCamera.

Class Methods
(nonnull instancetype)	+ cameraWithPoint:zoom:rotation:tilt:
	Factory method for class NCCamera.

Properties
NCPoint *	point
	point the camera is looking at Point
float	zoom
	zoom level.
float	rotation
	Map azimuth in degrees: angle between Location North (top of the image) and the direction of interest on the view plane, in the range [0, 360).
float	tilt
	Camera tilt in degrees. 0 means vertical downward (map seen from above). Positive values tilt the eye toward the horizon; the renderer clamps tilt to device limits when applying.

Detailed Description

Class describing position of the camera.

Referenced from LocationWindow.

Swift code snippet:

        // Create camera with constructor
        let newPoint = NCPoint(x: 100.0, y: 200.0)
        let newCamera = NCCamera(point: newPoint, zoom: 50.0, rotation: 0.0, tilt: 0.0)
        print("Created camera with point (\‍(newPoint.x), \‍(newPoint.y)), zoom 50.0, rotation 0°, tilt 0°")

Objective C code snippet:

    // Create camera with constructor
    NCPoint *newPoint = [[NCPoint alloc] initWithX:100.0 y:200.0];
    NCCamera *newCamera = [[NCCamera alloc] initWithPoint:newPoint zoom:50.0 rotation:0.0 tilt:0.0];
    NSLog(@"Created camera with point (%.2f, %.2f), zoom 50.0, rotation 0°, tilt 0°", newPoint.x, newPoint.y);
