public class Point

Methods

Point

Initializes a new instance of the Point class with default coordinates (0, 0).

Point()

Initializes a new instance of the Point class by copying coordinates from another point.

Point(Point other)

Initializes a new instance of the Point class with the specified coordinates.

Point(int x, int y)

Parameters

[in] other The point from which to copy coordinates.

[in] x The x-coordinate of the point.

[in] y The y-coordinate of the point.

This

Gets or sets the coordinate value at the specified index.

int this[int index]

Parameters

[in] index The index of the coordinate value to get or set. Index 0 corresponds to the x-coordinate, and index 1 corresponds to the y-coordinate.

Return Value

Returns the value of the coordinate at the specified index.

Set

Sets the coordinates of a point.

void Set(int x, int y)

Parameters

[in] x The new x-coordinate of a point.

[in] y The new y-coordinate of a point.

DistanceTo

Calculates the distance between the current point and the specified target point.

double DistanceTo(Point pt)

Parameters

[in] pt The target point to which the distance is calculated.

Return Value

A value representing the distance between the current point and the specified target point.

TransformCoordinates

Transforms the coordinates of a point using a given transformation matrix.

static Point TransformCoordinates(Point originalPoint, double transformationMatrix[9])

Parameters

[in] originalPoint The original point to transform.

[in] transformationMatrix The transformation matrix to apply to the coordinates.

Return Value

Returns a new Point object with the transformed coordinates.
