Method Details

hitTest

public boolean hitTest(@NonNull
 GLMapViewRenderer mapView,
 float screenX,
 float screenY,
 int paddingLeft,
 int paddingRight,
 int paddingTop,
 int paddingBottom)

Tests if a screen point is inside the drawable.

Parameters:

mapView - renderer where the drawable is displayed

screenX - x coordinate in screen pixels

screenY - y coordinate in screen pixels

paddingLeft - left padding in screen pixels

paddingRight - right padding in screen pixels

paddingTop - top padding in screen pixels

paddingBottom - bottom padding in screen pixels

Returns:

true if point is inside the drawable

setPosition

public void setPosition(@NonNull
 MapPoint position)

Sets position of the drawable on the map.

 image.setPosition(MapPoint.CreateFromGeoCoordinates(40.7, -74.0)); // New York
 

Parameters:

position - position in internal map coordinates

See Also:

• MapPoint

getPosition

public MapPoint getPosition()

Position of image

Returns:

position of image in internal map coordinates

setScale

public void setScale(double scale)

Scale of vector object

Parameters:

scale - new scale for vector object

getScale

public double getScale()

Scale of vector object

Returns:

scale of vector object

setAngle

public void setAngle(float angle)

Sets angle of image. image.setAngle(45);

Parameters:

angle - angle to set

getAngle

public float getAngle()

Angle of image

Returns:

angle of image in degrees.

getWidth

public int getWidth()

Loaded image width.

Returns:

width of image in pixels.

getHeight

public int getHeight()

Loaded image height.

Returns:

height of image in pixels.

setRotatesWithMap

public void setRotatesWithMap(boolean rotate)

Sets whether image rotates with the map.

Parameters:

rotate - true to rotate with map

isRotatesWithMap

public boolean isRotatesWithMap()

Whether image rotates with the map

Returns:

true if image rotates with the map

setOffset

public void setOffset(int offsetX,
 int offsetY)

Image offset from position. When offset is (0,0), bottom left corner of image is displayed at position image.setOffset(bmp.getWidth()/2, bmp.getHeight()/2); // image center displayed at position

Parameters:

offsetX - x offset of image

offsetY - y offset of image

See Also:

• setPosition(MapPoint)

setTransformMode

public void setTransformMode(int transformMode)

If drawable contains vector object and you will use position and scale to transform vector object, then set this to TransformMode.Custom.

Parameters:

transformMode - mode of transforming position and scale

getOffset

@NonNull
public MapPoint getOffset()

Offset of image

Returns:

offset of image in pixels
