Provides access to methods and properties of envelopes.
**Note:** the IEnvelope interface has been superseded by IEnvelope2. Please consider using the more recent version.

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Envelopes are the rectangular window that contain a specific element. All Geometry objects have an envelope defined by the XMin, XMax, YMin, and YMax of the object. Envelopes can also serve as the viewing area for a particular view screen or data frame.

Description |
||
---|---|---|

CenterAt | Moves this envelope so it is centered at p. | |

DefineFromPoints | Defines the envelope to cover all the points. | |

Depth | The depth of the envelope. | |

Dimension | The topological dimension of this geometry. | |

Envelope | Creates a copy of this geometry's envelope and returns it. | |

Expand | Moves the X and Y coordinates of the sides toward or away from each other. | |

ExpandM | Moves the measure of the sides toward or away from each other. | |

ExpandZ | Moves the Z attribute of the sides toward or away from each other. | |

GeometryType | The type of this geometry. | |

GeoNormalize | Shifts longitudes, if need be, into a continuous range of 360 degrees. | |

GeoNormalizeFromLongitude | Normalizes longitudes into a continuous range containing the longitude. This method is obsolete. | |

Height | The height of the envelope. | |

Intersect | Adjusts to include only the area also included by inEnvelope. | |

IsEmpty | Indicates whether this geometry contains any points. | |

LowerLeft | The lower left corner. | |

LowerRight | The lower right corner. | |

MMax | The maximum measure value in the area of the envelope. | |

MMin | The minimum measure value in the area of the envelope. | |

Offset | Moves the sides x units horizontally and y units vertically. | |

OffsetM | Moves the sides m units. | |

OffsetZ | Moves the sides z units. | |

Project | Projects this geometry into a new spatial reference. | |

PutCoords | Constructs an envelope from the coordinate values of lower, left and upper, right corners. | |

QueryCoords | Returns the coordinates of lower, left and upper, right corners. | |

QueryEnvelope | Copies this geometry's envelope properties into the specified envelope. | |

SetEmpty | Removes all points from this geometry. | |

SnapToSpatialReference | Moves points of this geometry so that they can be represented in the precision of the geometry's associated spatial reference system. | |

SpatialReference | The spatial reference associated with this geometry. | |

Union | Adjusts to overlap inEnvelope. | |

UpperLeft | The upper left corner. | |

UpperRight | The upper right corner. | |

Width | The width of the envelope. | |

XMax | The position of the right side. | |

XMin | The position of the left side. | |

YMax | The position of the top. | |

YMin | The position of the bottom. | |

ZMax | The maximum Z value in the area of the envelope. | |

ZMin | The minimum Z value in the area of the envelope. |

Interfaces | Description |
---|---|

IGeometry | Provides access to members that describe properties and behavior of all geometric objects. |

CoClasses and Classes | Description |
---|---|

Envelope | A rectangle with sides parallel to a coordinate system defining the extent of another geometry; optionally has min and max measure, height and ID attributes. |

[C#]

The following C# code shows how to create an envelope from coordinates:

IEnvelope env = new EnvelopeClass() as IEnvelope;

env.PutCoords(-10, -5, 10, 5);

[Visual Basic 6.0]

The following Visual Basic code shows how to create an envelope from coordinates:

Private Sub btnPutCoords_Click()

m_pEnveLope.PutCoords Val(edtXmin.Text), Val(edtYmin.Text), _

Val(edtXmax.Text), Val(edtYmax.Text)

End Sub
