Detailed Description

Describes a line in 2D space. A line is positioned in the plane with an axis (a gp_Ax2d object) which gives the line its origin and unit vector. A line and an axis are similar objects, thus, we can convert one into the other. A line provides direct access to the majority of the edit and query functions available on its positioning axis. In addition, however, a line has specific functions for computing distances and positions. See Also GccAna and Geom2dGcc packages which provide functions for constructing lines defined by geometric constraints gce_MakeLin2d which provides functions for more complex line constructions Geom2d_Line which provides additional functions for constructing lines and works, in particular, with the parametric equations of lines

Constructor & Destructor Documentation

GLin2d.GLin2d ( )

Creates a Line corresponding to X axis of the reference coordinate system.

GLin2d.GLin2d ( GAx2d A )

Creates a line located with A.

GLin2d.GLin2d	(	GPnt2d	P,
		GDir2d	V
	)

is the location point (origin) of the line and <V> is the direction of the line.

GLin2d.GLin2d	(	double	A,
		double	B,
		double	C
	)

Creates the line from the equation A*X + B*Y + C = 0.0 Raises ConstructionError if Sqrt(A*A + B*B) <= Resolution from gp. Raised if Sqrt(A*A + B*B) <= Resolution from gp.

Member Function Documentation

double GLin2d.Angle ( GLin2d Other )

Computes the angle between two lines in radians.

void GLin2d.Coefficients	(	double[]	A,
		double[]	B,
		double[]	C
	)

Returns the normalized coefficients of the line : A * X + B * Y + C = 0.

boolean GLin2d.Contains	(	GPnt2d	P,
		double	LinearTolerance
	)

Returns true if this line contains the point P, that is, if the distance between point P and this line is less than or equal to LinearTolerance.

GDir2d GLin2d.Direction ( )

Returns the direction of the line.

double GLin2d.Distance ( GPnt2d P )

Computes the distance between <me> and the point

.

double GLin2d.Distance ( GLin2d Other )

Computes the distance between two lines.

GPnt2d GLin2d.Location ( )

Returns the location point (origin) of the line.

GLin2d GLin2d.Mirrored ( GPnt2d P )

Performs the symmetrical transformation of a line with respect to the point

which is the center of the symmetry

GLin2d GLin2d.Mirrored ( GAx2d A )

Performs the symmetrical transformation of a line with respect to an axis placement which is the axis of the symmetry.

GLin2d GLin2d.Normal ( GPnt2d P )

Computes the line normal to the direction of <me>, passing through the point

.

GAx2d GLin2d.Position ( )

Returns the axis placement one axis whith the same location and direction as <me>.

GLin2d GLin2d.Reversed ( )

Reverses the positioning axis of this line. Note: - Reverse assigns the result to this line, while - Reversed creates a new one.

GLin2d GLin2d.Rotated	(	GPnt2d	P,
		double	Ang
	)

Rotates a line. P is the center of the rotation. Ang is the angular value of the rotation in radians.

GLin2d GLin2d.Scaled	(	GPnt2d	P,
		double	S
	)

Scales a line. S is the scaling value. Only the origin of the line is modified.

void GLin2d.SetDirection ( GDir2d V )

Changes the direction of the line.

void GLin2d.SetLocation ( GPnt2d P )

Changes the origin of the line.

void GLin2d.SetPosition ( GAx2d A )

Complete redefinition of the line. The "Location" point of is the origin of the line. The "Direction" of is the direction of the line.

double GLin2d.SquareDistance ( GPnt2d P )

Computes the square distance between <me> and the point

.

double GLin2d.SquareDistance ( GLin2d Other )

Computes the square distance between two lines.

GLin2d GLin2d.Transformed ( GTrsf2d T )

Transforms a line with the transformation T from class Trsf2d.

GLin2d GLin2d.Translated ( GVec2d V )

Translates a line in the direction of the vector V. The magnitude of the translation is the vector's magnitude.

GLin2d GLin2d.Translated	(	GPnt2d	P1,
		GPnt2d	P2
	)

Translates a line from the point P1 to the point P2.
