Full Name: aspose.gis.Extent

Aspose.PSD Version: 25.9.0

Constructors

Name	Description
Extent()	Creates new instance.
Extent(srs)	Creates new instance.
Extent(x_min, y_min, x_max, y_max, srs)	Creates new instance.

Properties

Name	Type	Access	Description
center	IPoint	r	Center of the extent.
height	double	r	Height of the extent.
is_valid	bool	r	Determines whether this Extent is valid.
spatial_reference_system	SpatialReferenceSystem	r/w	SpatialReferenceSystem associated with this extent. Can be if Extent.spatial_reference_system is unknown. Use Aspose.Gis.Extent.GetTransformed(Aspose.Gis.SpatialReferencing.SpatialReferenceSystem) in order to transform extent between difference spatial reference systems.

y_max	double	r/w	Maximum value of the Y coordinate.
y_min	double	r/w	Minimum value of the Y coordinate.
