This abstract class is the base class of the rendering styles.
Library: ilvmaps
A rendering style is used by the renderers to define the graphic style of the graphic objects representing vector map features. Instances of IlvMapRenderingStyle
are shared objects. As a consequence, they should never be deleted. The memory management should be performed using the lock and unLock mechanism.
|
protected |
Initializes a new instance of this rendering style.
display | The display used to create the graphic palettes. |
|
protected |
Initializes a new instance of the renderer style as a copy of another one.
Since this class is abstract, this copy constructor is protected.
source | The object to be copied. |
|

Destructor.
The destructor of this class is protected, because instances of IlvMapRenderingStyle
are potentially shared by several objects.
|
pure virtual |
Copies the object.
