Detailed Description

This class defines an interface for callbacks used by the contouring functionality of the Terrain SDK. Each method has a default implementation that does nothing.

drawLine()

virtual void TSLTerrainContourCallbacks::drawLine ( double x1, double y1, double x2, double y2, double attribute )

virtual

This callback is invoked when a line needs to be rendered following a draw SimpleContour() operation. The default implementation does nothing.

Parameters

x1	The starting X coordinate of the line.
y1	The starting Y coordinate of the line.
x2	The ending X coordinate of the line.
y2	The ending X coordinate of the line.
attribute	The value corresponding to the attribute parameter passed to the drawSimpleContour() call.

drawPolygon()

virtual void TSLTerrainContourCallbacks::drawPolygon ( TSLTerrainContourVertexList * vertices, double minAttribute, double maxAttribute )

virtual

This callback is invoked when a polygon needs to be rendered following a draw PolygonContour() operation. The default implementation does nothing.

Parameters

vertices	a TSLContourVertexList that contains the coordinates of the points of the polygon. The vertices may return the vertices representing a keyholed polygon if the contour contains holes.
minAttribute	The value of the minAttribute parameter passed to the draw PolygonContour() method.
maxAttribute	The value of the maxAttribute parameter passed to the draw PolygonContour() method.

drawPolyline()

virtual void TSLTerrainContourCallbacks::drawPolyline ( TSLTerrainContourVertexList * vertices, double attribute )

virtual

This callback is invoked when a polyline needs to be rendered following a drawContour() operation. The default implementation does nothing.

Parameters

vertices	a TSLContourVertexList that contains the coordinates of the points that need to be rendered.
attribute	The value corresponding to the attribute parameter passed to the drawContour() call.

drawText()

virtual void TSLTerrainContourCallbacks::drawText ( double x, double y, double rotation, const char * text, TSLVerticalAlignment textAlignment, double attribute )

virtual

This callback is invoked when the text label for a contour line needs to be rendered. The default implementation does nothing.

Parameters

x	The X coordinate of the text.
y	The Y coordinate of the text.
rotation	The angle of rotation for the text in radians.
text	The prefix passed in as a parameter to the drawContour() method.
textAlignment	The vertical alignment of the text.
attribute	The value corresponding to the attribute parameter passed to the drawSimpleContour() call.
