ProfileExportType
Types of export for elevation profiles.
Definition: qgis.h:2677
@ Features3D
Export profiles as 3D features, with elevation values stored in exported geometry Z values.
Abstract base class for objects which generate elevation profiles.
Interface for classes which can generate elevation profiles.
Contains information about the context in which a coordinate transform is executed.
Base class for feedback objects to be used for cancellation of something running in a worker thread.
Definition: qgsfeedback.h:45
Handles exports of elevation profiles in various formats in a background task.
ExportResult
Results of exporting the profile.
Q_ENUM(ExportResult)
QString error() const
Returns a descriptive error message, if available.
Handles exports of elevation profiles in various formats.
QgsProfileExporter & operator=(const QgsProfileExporter &other)=delete
QgsProfileExporter cannot be copied.
QgsProfileExporter(const QgsProfileExporter &other)=delete
QgsProfileExporter cannot be copied.
Encapsulates properties and constraints relating to fetching elevation profiles from different source...
Abstract base class for long running background tasks.
