Detailed Description

This class stored a single point. As all coordinates it is store as an integer with a resolution of 32 bit. The physical coordinates can be calculated by a multiplication with the databaseunits ([[MacroClassDrawingField|class drawingField]])

Example:

 point p;
 p.set(10000,10000);
 int x=p.x();

Member Function Documentation

point::point( )

creates a point.

point::point( point p )

creates a point containing a copy of p

point::point(int x,int y)

constructs a point with coordinates x and y.

double point::distanceTo(point p2)

Returns: the distance to the p2

double point::distanceToLine(point p1, point p2)

Returns: the shortest distance to the line p1 to p2. The value is negative it the point is left of the line from p1 to p2.

double point::distanceToLineAbs(point p1, point p2)

Returns: the shortest distance to the line p1 to p2. The value is always positive or 0.

double point::length()

Returns: the distance to the origin

void point::set(int x, int y)

Set the x and y coordinates.

void point::setX(int x)

Set the x coordinate.

void point::setY(int y)

Set the y coordinate.

int point::x()

Returns: x-coordinate of the point

int point::y()

Returns: y-coordinate of the point
