Constructor Detail

FixedPixelCircle

public FixedPixelCircle(org.mapsforge.core.model.LatLong latLong,
                        float radius,
                        org.mapsforge.core.graphics.Paint paintFill,
                        org.mapsforge.core.graphics.Paint paintStroke)

Parameters:

latLong - the initial center point of this circle (may be null).

radius - the initial non-negative radius of this circle in pixels.

paintFill - the initial Paint used to fill this circle (may be null).

paintStroke - the initial Paint used to stroke this circle (may be null).

Throws:

java.lang.IllegalArgumentException - if the given radius is negative or Float.NaN.

FixedPixelCircle

public FixedPixelCircle(org.mapsforge.core.model.LatLong latLong,
                        float radius,
                        org.mapsforge.core.graphics.Paint paintFill,

                        boolean keepAligned)

Parameters:

latLong - the initial center point of this circle (may be null).

radius - the initial non-negative radius of this circle in pixels.

paintFill - the initial Paint used to fill this circle (may be null).

paintStroke - the initial Paint used to stroke this circle (may be null).

keepAligned - if set to true it will keep the bitmap aligned with the map, to avoid a moving effect of a bitmap shader.

Throws:

java.lang.IllegalArgumentException - if the given radius is negative or Float.NaN.

Method Detail

contains

public boolean contains(org.mapsforge.core.model.Point center,
                        org.mapsforge.core.model.Point point)

getRadiusInPixels

protected int getRadiusInPixels(double latitude,
                                byte zoomLevel)

Overrides:

getRadiusInPixels in class Circle

Returns:

the non-negative radius of this circle in pixels.

isScaleRadius

public boolean isScaleRadius()

Returns:

true if it scales the radius with the combined device/user scale factor, false otherwise.

setScaleRadius

public void setScaleRadius(boolean scaleRadius)

Parameters:

scaleRadius - if set to true it will scale the radius with the combined device/user scale factor.
