Detailed Description

general vertexlist and array and vector path functions and classes.

All ways to have polygons and polylines stored and drawn by a drawing context are placed here. Polygon or polylines can be list based or array based. The vector path is the structure which can be used to drawn almost anything. Basic primtives can always be converted to a vector path, and drawn that way.

Enumeration Type Documentation

enum a2dSegType

defines the type of a segment in a a2dLineSegment

Enumerator
a2dNORMAL_SEG	not specific or part of outer contour
a2dLINK_SEG	links an outside contour with a hole
a2dHOLE_SEG	this segmnet is part of a hole

Definition at line 145 of file polyver.h.

Function Documentation

bool CalcR	(	double	begin_x,
		double	begin_y,
		double	middle_x,
		double	middle_y,
		double	end_x,
		double	end_y,
		double &	radius,
		a2dPoint2D &	center_p
	)

Calculation of center for the Arc.

Parameters

begin_x	x start point of arc.
begin_y	y start point of arc.
middle_x	x middle point of arc.
middle_y	y middle point of arc.
end_x	x end point of arc.
end_y	y end point of arc.
radius	radius of the circle calculated
center_p	the center calculated

Returns

true if the arc is indeed an Arc if a straight line return false.

bool CalcR	(	double	begin_x,
		double	begin_y,
		double	middle_x,
		double	middle_y,
		double	end_x,

		double &	beginrad,
		double &	midrad,
		double &	endrad,
		double &	phit
	)

Calculation of center for the Arc.

Parameters

begin_x	x start point of arc.
begin_y	y start point of arc.
middle_x	x middle point of arc.
middle_y	y middle point of arc.
end_x	x end point of arc.
end_y	y end point of arc.
radius	radius of the circle calculated
center_x	x of the center calculated
center_y	y of the center calculated
beginrad	calculated starting angle in radians
midrad	calculated middle angle in radians
endrad	calculated end angle in radians
phit	total calculated in radians (AntiClockwise positif, else negatif )

Returns

true if the arc is indeed an Arc if a straight line return false.

Definition at line 4797 of file polyver.cpp.

double ClclDistSqrPntLine	(	const a2dPoint2D &	p,
		const a2dPoint2D &	p1,
		const a2dPoint2D &	p2
	)

Calculate the square distance between a point and a line.

This returns DBL_MAX if the point is beyond the edges

Definition at line 103 of file polyver.cpp.

bool InArc	(	double	angle,
		double	start,
		double	end,
		bool	clockwise
	)

is the angle within the arc segment taking into account drawing from start to end in clockwise or anti clocwise direction.
