Detailed Description
MgEnvelope represents a bounding box defined in terms of a lower left coordinate and an upper right coordinate.Public Member Functions | |
| bool | Contains (MgEnvelope *envelope) |
| Tests whether the given envelope lies completely inside this Envelope (inclusive of the boundary). | |
| bool | Contains (MgCoordinate *coordinate) |
| Tests whether the given coordinate lies in or on this envelope. | |
| void | ExpandToInclude (MgEnvelope *envelope) |
| Enlarges the boundary of the envelope so that it contains the given envelope. | |
| void | ExpandToInclude (MgCoordinate *coordinate) |
| Enlarges the boundary of the envelope so that it contains the given coordinate. | |
| double | GetDepth () |
| double | GetHeight () |
| MgCoordinate * | GetLowerLeftCoordinate () |
| Returns the lower left coordinate of the envelope. | |
| MgCoordinate * | GetUpperRightCoordinate () |

| bool | Intersects (MgEnvelope *envelope) |
| Tests if the region defined by another envelope overlaps (intersects) the region of this envelope. | |
| bool | IsNull () |
| void | MakeNull () |
| Makes this envelope a "null" envelope. | |
| MgEnvelope (MgEnvelope *envelope) | |
| Constructs and initializes an envelope that is a copy of another. | |
| MgEnvelope (double xMin, double yMin, double xMax, double yMax) | |
| Constructs and initializes an envelope for a region defined by two coordinates , given as four doubles. | |
