Method Detail

setViewSize

public void setViewSize(int width,
                        int height)

getMapViewCenter

public float[] getMapViewCenter()

Get pivot horizontal / vertical relative to view center. e.g. pivotY 0.5 is usually preferred for navigation, moving center to 25% of view height. Range is [-1, 1].

setMapViewCenter

public void setMapViewCenter(float pivotX,
                             float pivotY)

Set pivot horizontal / vertical relative to view center. e.g. pivotY 0.5 is usually preferred for navigation, moving center to 25% of view height. Range is [-1, 1].

moveMap

public void moveMap(float mx,
                    float my)

Moves this Viewport by the given amount of pixels.

Parameters:

mx - the amount of pixels to move the map horizontally.

my - the amount of pixels to move the map vertically.

applyRotation

public static void applyRotation(double mx,
                                 double my,
                                 float bearing,
                                 Point out)

Parameters:

mx - the amount of pixels to move the map horizontally.

my - the amount of pixels to move the map vertically.

bearing - the bearing to rotate the map.

out - the position where to move.

scaleMap

public boolean scaleMap(float scale,
                        float pivotX,
                        float pivotY)

Scale map by scale width center at pivot in pixel relative to view center. Map scale is clamp to MIN_SCALE and MAX_SCALE.

Returns:

true if scale was changed

rotateMap

public void rotateMap(double radians,
                      float pivotX,
                      float pivotY)

Rotate map by radians around pivot. Pivot is in pixel relative to view center.

setRotation

public void setRotation(double degree)

rollMap

public void rollMap(float move)

setRoll

public void setRoll(double degree)

tiltMap

public boolean tiltMap(float move)

setTilt

public boolean setTilt(float tilt)

setMapPosition

public void setMapPosition(MapPosition mapPosition)

getSyncViewport

public final Viewport getSyncViewport()

synchronize on this object when doing multiple calls on it

getSyncViewport

public boolean getSyncViewport(Viewport v)

getSyncMapPosition

public boolean getSyncMapPosition(MapPosition mapPosition)
