getCorners

public static int[][] getCorners(Paint paint,
                                 int x1,
                                 int x2,
                                 int y1,
                                 int y2)

An integer wrapper for the getCorners function

Parameters:

paint - the main JavaFX class of the program

x1 - the first x-coordinate

x2 - the second x-coordinate

y1 - the first y-coordinate

y2 - the second y-coordinate

Returns:

two pairs of coordinates in the form { {x1, y1}, {x2, y2} } where the first pair is the top left corner

getCorners

public static double[][] getCorners(Paint paint,
                                    double x1,
                                    double x2,
                                    double y1,
                                    double y2)

Takes a pair of coordinates and returns a pair of coordinates matching the same square where the first coordinate pair is the top left corner and the second is the bottom right, and the box does not extend past the edge of the canvas

Parameters:

paint - the main JavaFX class of the program

x1 - the first x-coordinate

x2 - the second x-coordinate

y1 - the first y-coordinate

y2 - the second y-coordinate

Returns:

two pairs of coordinates in the form { {x1, y1}, {x2, y2} } where the first pair is the top left corner and the second pair is the bottom right
