LVectorObject
Description
The LVectorObject class is used in conjunction with the main vector class LVectorBase and the vector layer class LVectorLayer. This class contains the functionality for dealing with vector objects, this class contains functions for the following:
Removing a vector object from a vector layer
Getting and setting object attributes such as pen style, brush color, pen width, etc.
Getting information about a vector object such as bounding rectangle, bounding parallelogram, selection status, etc.
Modifying vector objects through rotation, scaling and translation
Determining the type of vector object being used
When calling some functions of the LVectorObject class, the associated vector data is changed. To be notified of these changes, you can override the LVectorBase::StartChanging and LVectorBase::EndChanging functions. For more information, refer to Bitmap and Vector Change Notifications and Notification Categories.
If you derive a class from LVectorObject, the macros defined in Wrapper Macros may be helpful.
Required Libraries
You must load all required libraries using LBase::LoadLibraries before using the classes.
