Member Function Documentation

elevationLimit()

double QgsAbstractProfileSurfaceGenerator::elevationLimit

(

)

const

Returns the elevation limit, which is used when symbology() is Qgis::ProfileSurfaceSymbology::FillBelow or Qgis::ProfileSurfaceSymbology::FillAbove to limit the fill to a specific elevation range.

By default this is NaN, which indicates that there is no elevation limit.

lineSymbol()

QgsLineSymbol * QgsAbstractProfileSurfaceGenerator::lineSymbol

const

Returns the line symbol to be used for rendering the results.

setElevationLimit()

void QgsAbstractProfileSurfaceGenerator::setElevationLimit

(

double

limit

)

Sets the elevation limit, which is used when symbology() is Qgis::ProfileSurfaceSymbology::FillBelow or Qgis::ProfileSurfaceSymbology::FillAbove to limit the fill to a specific elevation range.

Set to NaN to indicate that there is no elevation limit.
