Ellipse specific access methods.
This class represents the access methods that are specific to an ellipse. They also allow setting of rendering attributes.
Rendering attributes can be set directly to this geometry using the inherited TSLEntityBase::setRendering method. This is called 'Entity Rendering'.
Rendering can be applied to a large range of geometry using 'Feature Rendering' which is set by the datalayer using TSLDataLayer::addFeatureRendering which creates a featureID. The featureID can then have attributes applied to it using TSLDataLayer::setFeatureRendering.
A featureID can be applied to geometry on creation, or it can be added later using TSLEntityBase::featureID.
Valid Rendering Attributes for TSLEllipse:
The above is not a complete list, see TSLRenderingAttributeInt, TSLRenderingAttributeDouble and TSLRenderingAttributeBool for more details.

| const TSLCoord & TSLEllipse::centre | ( | ) | const |
Query the centre of the ellipse.
Returns the coordinate of the centre of the ellipse.
| void TSLEllipse::centre | ( | const TSLCoord & | newPosition | ) |
Sets the centre of the ellipse.
| newPosition | New centre of the ellipse. |

static |
Creates an ellipse with the specified parameters.
This call should only be used for temporary entities. For example, this call may be used to create entities that are used in the spatial tests.
All angles are in radians, +ve anti-clockwise from the +ve X axis.
| featureID | ID of the feature code to assign to the entity. This is used when rendering map features if no specific attribute set has been created for the entity. |
| cx | X coordinate of centre of ellipse. |
| cy | Y coordinate of centre of ellipse. |
| radx | Radius of ellipse along X axis, before rotation. |
| rady | Radius of ellipse along Y axis, before rotation. If 0, rady is assumed to be the same as radx. |
| rotation | Angle of rotation of ellipse, about cx,cy. |
|
static |
Query whether the entity is an ellipse.
If this entity is an ellipse, returns an accessor, otherwise returns NULL.
When querying Optimised maps this query may return NULL.
