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
intermediatePointA point that is on the arc.
endPointThe arc end point.
IlvDrawRule IlvMapGeneralPath::getDrawRule ( ) const

Returns the current draw rule used for this IlvMapGeneralPath.

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
endPointThe specified point.
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
newPointThe new point.
virtual void IlvMapGeneralPath::setAlpha ( IlvIntensity  alpha)
virtual

Changes the alpha value for this object.

Parameters
alphathe alpha value defining the transparency.

Reimplemented from IlvGraphic.

void IlvMapGeneralPath::setBackground ( IlvColor bg)
virtual

Changes the background of this object.

Parameters
bgThe new background color.

Reimplemented from IlvGraphic.

void IlvMapGeneralPath::setDrawRule ( IlvDrawRule  rule)

Sets the draw rule for this IlvMapGeneralPath.

Parameters
ruleThe new draw rule.
void IlvMapGeneralPath::setFillBackground ( IlvColor bg)

Change the fill background of this object.

Parameters
bgThe new fill background color.
void IlvMapGeneralPath::setFillForeground ( IlvColor fg)

Change the fill foreground of this object.

Parameters
fgThe new fill foreground color.
void IlvMapGeneralPath::setFillPalette ( IlvPalette pal)

Sets the palette used to fill this object.

Parameters
palThe new palette.
void IlvMapGeneralPath::setForeground ( IlvColor fg)
virtual

Changes the foreground of this object.

Parameters
fgThe new foreground color.

Reimplemented from IlvGraphic.

void IlvMapGeneralPath::setPalette ( IlvPalette pal)
virtual

Changes the palette for this object.

Parameters
palThe new palette.

Reimplemented from IlvGraphic.
