Implements SFCOM IPoint methods.
|
Create a (0,0) point. |
|
Make a copy of this object. This method relates to the SFCOM IGeometry::clone() method. This method is the same as the C function OGR_G_Clone().
Implements OGRGeometry. |
|
Clear geometry information. This restores the geometry to it's initial state after construction, and before assignment of actual geometry. This method relates to the SFCOM IGeometry::Empty() method. This method is the same as the C function OGR_G_Empty(). Implements OGRGeometry. |
|
Returns two if two geometries are equivalent. This method is the same as the C function OGR_G_Equal().
Implements OGRGeometry. |
|
Convert a geometry into well known binary format. This method relates to the SFCOM IWks::ExportToWKB() method. This method is the same as the C function OGR_G_ExportToWkb().
Implements OGRGeometry. |
|
Convert a geometry into well known text format. This method relates to the SFCOM IWks::ExportToWKT() method. This method is the same as the C function OGR_G_ExportToWkt().
Implements OGRGeometry. |
|
Convert geometry to strictly 2D. In a sense this converts all Z coordinates to 0.0. This method is the same as the C function OGR_G_FlattenTo2D(). Implements OGRGeometry. |
|
Get the dimension of the coordinates in this object. This method corresponds to the SFCOM IGeometry::GetDimension() method. This method is the same as the C function OGR_G_GetCoordinateDimension().
Implements OGRGeometry. |
|
Get the dimension of this object. This method corresponds to the SFCOM IGeometry::GetDimension() method. It indicates the dimension of the object, but does not indicate the dimension of the underlying space (as indicated by OGRGeometry::getCoordinateDimension()). This method is the same as the C function OGR_G_GetDimension().
Implements OGRGeometry. |
|
Computes and returns the bounding envelope for this geometry in the passed psEnvelope structure. This method is the same as the C function OGR_G_GetEnvelope().
Implements OGRGeometry. |
|
Fetch WKT name for geometry type. There is no SFCOM analog to this method. This method is the same as the C function OGR_G_GetGeometryName().
Implements OGRGeometry. |
|
Fetch geometry type. Note that the geometry type may include the 2.5D flag. To get a 2D flattened version of the geometry type apply the wkbFlatten() macro to the return result. This method is the same as the C function OGR_G_GetGeometryType().
Implements OGRGeometry. |
|
Fetch X coordinate. Relates to the SFCOM IPoint::get_X() method.
|
|
Fetch Y coordinate. Relates to the SFCOM IPoint::get_Y() method.
|
|
Fetch Z coordinate. Relates to the SFCOM IPoint::get_Z() method.
|
|
Assign geometry from well known binary data. The object must have already been instantiated as the correct derived type of geometry object to match the binaries type. This method is used by the OGRGeometryFactory class, but not normally called by application code. This method relates to the SFCOM IWks::ImportFromWKB() method. This method is the same as the C function OGR_G_ImportFromWkb().
Implements OGRGeometry. |
|
Assign geometry from well known text data. The object must have already been instantiated as the correct derived type of geometry object to match the text type. This method is used by the OGRGeometryFactory class, but not normally called by application code. This method relates to the SFCOM IWks::ImportFromWKT() method. This method is the same as the C function OGR_G_ImportFromWkt().
Implements OGRGeometry. |
|
Assign point X coordinate. There is no corresponding SFCOM method. |
|
Assign point Y coordinate. There is no corresponding SFCOM method. |
|
Assign point Z coordinate. Setting a zero zIn value will make the point 2D, and setting a non-zero value will make the point 3D (wkbPoint|wkbZ). There is no corresponding SFCOM method. |
|
Apply arbitrary coordinate transformation to geometry. This method will transform the coordinates of a geometry from their current spatial reference system to a new target spatial reference system. Normally this means reprojecting the vectors, but it could include datum shifts, and changes of units. Note that this method does not require that the geometry already have a spatial reference system. It will be assumed that they can be treated as having the source spatial reference system of the OGRCoordinateTransformation object, and the actual SRS of the geometry will be ignored. On successful completion the output OGRSpatialReference of the OGRCoordinateTransformation will be assigned to the geometry. This method is the same as the C function OGR_G_Transform().
Implements OGRGeometry. |
|
Returns size of related binary representation. This method returns the exact number of bytes required to hold the well known binary representation of this geometry object. Its computation may be slightly expensive for complex geometries. This method relates to the SFCOM IWks::WkbSize() method. This method is the same as the C function OGR_G_WkbSize().
