HXLDCont (Class)

名称

HXLDCont — 代表 XLD 轮廓对象（-数组）的一个实例。

Base Class

HXLD — 代表扩展线描述 XLD（eXtended Line Descriptions）对象的实例（-数组）。

构造函数

`GenContourRegionXld`		Generate XLD contours from regions.
`GenContourPolygonXld`		Generate an XLD contour from a polygon (given as tuples).

Finalizer

This operator is not available as a class member but will be called automatically when the resources of the object instances are to be released. This occurs in the finalization stage of garbage collection, or upon an explicit call of the Dispose() method.

ClearObj Delete an iconic object from the database.
