Function Documentation

TL_DLL short TeRelation	(	const TeCoord2D &	c,
		const TeLine2D &	l
	)

Returns the relation between coordinate c and line l.

Parameters:

c	The coordinate.
l	The line.

Returns:

one of the relations: INSIDE, OUTSIDE or BOUNDARY.

Note:

It doesn't do box elimination, just uses from TeIsOnLine(coordinate, line) elimination

TL_DLL short TeRelation	(	const TePolygon &	pRed,
		const TePolygon &	pBlue
	)

This function returns the relation between two polygons.

Parameters:

pRed	The first polygon.
pBlue	The second polygon.

Returns:

one of the relations: TeEQUALS, TeDISJOINT, TeTOUCHES, TeWITHIN (pRed IS WITHIN pBlue), TeCONTANS (pBlue CONTAINS pRed), TeOVERLAPS, TeCOVEREDBY (pRed IS COVERED BY pBlue) or TeCOVERS (pRed COVERS pBlue).

Note:

Doesn't do box elimination. You must implement the test in your own functions.

TL_DLL short TeRelation	(	const TeLine2D &	line,
		const TePolygon &	pol
	)

This function returns the relation between a line and a polygon.

Parameters:

line	The line.
pol	The polygon.

Returns:

one of the relations: TeDISJOINT, TeTOUCHES, TeWITHIN (THE LINE IS WITHIN), TeCROSSES, TeCOVEREDBY (THE LINE IS COVERED BY).

Note:

Doesn't do box elimination. You must implement the test in your own functions.

TL_DLL short TeRelation	(	const TeLine2D &	lRed,
		const TeLine2D &	lBlue,
		const short &	relation
	)

This function returns the relation between two lines.

Parameters:

lRed	The first line.
lBlue	The second line.
relation	To return the relation that stop the search: TeDISJOINT, TeTOUCHES, TeWITHIN, TeCONTAINS, TeCROSSES, TeOVERLAPS, TeCOVEREDBY, TeCOVERS, TeEQUALS

Note:

Doesn't do box elimination. You must implement the test in your own functions.

TL_DLL short TeRelation	(	const TeCoord2D &	c,
		const TePolygonSet &	pSet
	)

Point in polygon set inside/outside/boundary code.

Parameters:

c	The coordinate to test.
pSet	The polygon set to test.

Returns:

one of the relations: INSIDE, OUTSIDE or BOUNDARY.

Note:

Does box elimination.

TL_DLL short TeRelation	(	const TePoint &	p,
		const TePolygon &	pol
	)

Point in polygon inside/outside/boundary code.

Parameters:

p	The coordinate to test.
pol	The polygon to test.

Returns:

one of the relations: INSIDE, OUTSIDE or BOUNDARY.

Note:

It doesn't do box elimination, just uses from TeRelation(coordinate, line) elimination

TL_DLL short TeRelation	(	const TeCoord2D &	c,
		const TePolygon &	pol
	)

Coordinate in polygon inside/outside/boundary code.

Parameters:

c	The coordinate to test.
pol	The polygon to test.

Returns:

one of the relations: INSIDE, OUTSIDE or BOUNDARY.

Note:

It doesn't do box elimination, just uses from TeRelation(coordinate, line) elimination

TL_DLL short TeRelation	(	const TeCoord2D &	c,
		const TeLinearRing &	r
	)

Point in polygon inside/outside/boundary code.

Parameters:

c	The coordinate to test.
r	The simple polygon to test.

Returns:

one of the relations: INSIDE, OUTSIDE or BOUNDARY.

Note:

The ring is treated as a simple polygon (no holes). Does box elimination.
