QgsAbstractProfileSurfaceGenerator (const QgsProfileRequest &request) | |
Constructor for QgsAbstractProfileSurfaceGenerator. | |
~QgsAbstractProfileSurfaceGenerator () override | |
double | 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. | |
QgsFillSymbol * | fillSymbol () const |
Returns the fill symbol to be used for rendering the results. | |
QgsLineSymbol * | lineSymbol () const |
Returns the line symbol to be used for rendering the results. | |
void | 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. | |
Qgis::ProfileSurfaceSymbology | symbology () const |
Returns the symbology type for rendering the results. | |

Access to feedback object of the generator (may be nullptr

Implements QgsAbstractProfileGenerator.
Definition at line 380 of file qgsrasterlayerprofilegenerator.cpp.
|
overridevirtual |
Returns flags which reflect how the profile generator operates.
Reimplemented from QgsAbstractProfileGenerator.
Definition at line 92 of file qgsrasterlayerprofilegenerator.cpp.
|
overridevirtual |
Generate the profile (based on data stored in the class).
Returns true
if the profile was generated successfully (i.e. the generation was not canceled early).
Implements QgsAbstractProfileGenerator.
Definition at line 99 of file qgsrasterlayerprofilegenerator.cpp.
|
overridevirtual |
Returns a unique identifier representing the source of the profile.
For generators associated with a map layer the source ID will match the layer's QgsMapLayer::id(). Other (non-map-layer) sources will have a different unique ID with its own custom interpretation.gen
Implements QgsAbstractProfileGenerator.
Definition at line 87 of file qgsrasterlayerprofilegenerator.cpp.

overridevirtual |
Takes results from the generator.
Ownership is transferred to the caller.
