Constructor Detail

CircleDrawable

public CircleDrawable(org.oscim.core.GeoPoint center,
                      double radiusKm)

Constructs a circle given the real-world radius in km. Keep in mind that this technique is computationally costly for circles with huge number or segments.

Parameters:

center - GeoPoint - center of the circle

radiusKm - Radius of the circle in kilometers.

CircleDrawable

public CircleDrawable(org.oscim.core.GeoPoint center,
                      double radiusKm,
                      Style style)

Constructs a circle given the real-world radius in km. Keep in mind that this technique is computationally costly for circles with huge number or segments.

Parameters:

center - GeoPoint - center of the circle

radiusKm - Radius of the circle in kilometers. The size of the circle may be distorted due to the Mercator projections properties.

style - FillableGeometryStyle with color and transparency information for the circle

CircleDrawable

public CircleDrawable(org.oscim.core.GeoPoint center,
                      double radiusKm,
                      int quadrantSegments,
                      Style style)

Constructs a circle given the real-world radius in km. Keep in mind that this technique is computationally costly for circles with huge number or segments.

Parameters:

center - GeoPoint - center of the circle

radiusKm - Radius of the circle in kilometers. The size of the circle may be distorted due to the Mercator projections properties.

quadrantSegments - the number of segments a quarter of circle will have. Use Circle.LOW_PRECISION for quick rendering, Circle.MEDIUM_PRECISION for good rendering and quality or Circle.HIGH_PRECISION for high quality.

style - FillableGeometryStyle with color and transparency information for the circle
