Detailed Description

This class can provide the Geometry associated with a Feature, and apply Geometry changes on that Feature.

this can for example be used to specify the Geometry that is used to edit or create a Feature.

See the related guide for an overview of the editing API.

See DefaultFeatureGeometryProvider for a default implementation that works for Features that use GeometryDataAnnotation.

The provided geometry is not necessarily the same geometry as the one used for painting. An example would be to modify the location and orientation of a vessel by editing it as an Ellipse, which also has a location and an orientation. This could be implemented by:

having GetGeometry return an Ellipse geometry based on the location and orientation stored in a Feature
having ApplyGeometry map the new Ellipse geometry back to a location and an orientation, and modify the Feature accordingly.

Similarly, a vessel feature could be created by creating an Ellipse geometry.

Since: 2020.1

Member Function Documentation

◆ ApplyGeometry()

Luciad.Models.Features.Feature Luciad.Models.Features.IFeatureGeometryProvider.ApplyGeometry	(	Luciad.Models.Features.Feature	originalFeature,
		Luciad.Geometries.Geometry	newGeometry
	)

Updates the original Feature using the modified Geometry, and returns it.

This Geometry is not necessarily the same geometry as the one used for painting. See IFeatureGeometryProvider for an example.

Parameters

originalFeature	the original `Feature`
newGeometry	a new `Geometry` to apply on the `Feature`

Returns: a new Feature, based on a modified Geometry

Implemented in Luciad.Models.Features.DefaultFeatureGeometryProvider.

◆ GetGeometry()

Luciad.Geometries.Geometry Luciad.Models.Features.IFeatureGeometryProvider.GetGeometry ( Luciad.Models.Features.Feature feature )

Return the geometry for a Feature (for example a Geometry using which a Geometry can be edited or created).

This Geometry is not necessarily the same geometry as the one used for painting.

See IFeatureGeometryProvider for more information.
