Method Detail

isOnSea

boolean isOnSea(int x,
                int y)

Check if a location on the image is white meaning it is at sea.

Parameters:

x - location to be checked

y - location to be checked

Returns:

true if the coordinates represent a coordinate at sea.

distanceToShore

double distanceToShore(javafx.geometry.Point2D point,
                       double max)
                throws java.io.IOException

Check the if there is shore within a certain radius of max. If there is the approximate distance is returned.

Parameters:

point - that is to be checked.

max - maximum radius

Returns:

maximum radius or approximate distance to the shore, whatever is smaller. If the approximate distance is returned it may be smaller than the actual distance to the nearest land.

Throws:

java.io.IOException

countLandPixels

int countLandPixels(javafx.geometry.Point2D point,
                    int radius,
                    java.util.List<ECircleSegment> segments)
             throws java.io.IOException

Count the number of black pixels in a circle around point with radius.

Parameters:

point - center point around which should be checked

radius - radius of the area that should be checked.

Returns:

number of pixels that represent land.

Throws:

java.io.IOException

getLocationAtOtherEndOfMap

javafx.geometry.Point2D getLocationAtOtherEndOfMap(javafx.geometry.Point2D location)

Retrieve a random ponint that is at sea.

Parameters:

location - near where the random point has to be located.

Returns:

point located on the sea.

getWidth

int getWidth()

£Retrieve the width of the map in pixels.

Returns:

width of the map

getHeight

int getHeight()

Retrieve the height of the map in pixels.

Returns:

height of the map
