Constructor & Destructor Documentation

IlvMapGeneralPath::IlvMapGeneralPath	(	IlvDisplay *	display,
		IlvDrawRule	drawRule = IlvStrokeAndFill,
		IlvPalette *	palette = 0
	)

Initializes a new empty IlvMapGeneralPath.

Member Function Documentation

void IlvMapGeneralPath::arcTo	(	const IlvPoint &	intermediatePoint,
		const IlvPoint &	endPoint
	)

Adds an arc defined by 3 points to the current path.

Adds an arc to the current path by drawing an arc from the current coordinates to the specified endPoint. This circular arc is constructed so that the current point is the arc starting point, the specified intermediatePoint is on the arc, and the specified endPoint is the arc end point.

Parameters

intermediatePoint	A point that is on the arc.
endPoint	The arc end point.

IlvDrawRule IlvMapGeneralPath::getDrawRule

(

Returns

The current IlvDrawRule

IlvPalette* IlvMapGeneralPath::getFillPalette

(

)

const

Returns the palette used to fill this object.

Returns

The palette used to fill this object.

void IlvMapGeneralPath::lineTo

(

const IlvPoint &

endPoint

)

Adds a straight segment to the current path.

Adds a point to the current path by drawing a straight line from the current coordinates to the new specified point.

Parameters

void IlvMapGeneralPath::moveTo

(

const IlvPoint &

newPoint

)

Adds a new point to the path by moving to the specified coordinates.

Adds a point to the path by moving to the specified coordinates.

Parameters

newPoint

The new point.
