| HOWTO: TalMapX Control의 XLayer 사용하는 방법. |
|
 요약
| |
이 문서는 TalMapX Control에서 제공하는 강력한 오브젝트(Object)인 XLayer Object를 사용하는 방법을 설명합니다.
사용자는 이 문서를 통해 XLayer - Shape, Polygon, PolyLing ... - 들을 생성하고 제거하는 방법을 학습할 수 있습니다.
사용자는 XLayer 관련 Object를 이용하여 원하는 스타일의 Layer들을 생성 및 추가/삭제 할 수 있습니다.
|
|
|
방법
| |
1. TalMapX Contorl의 CtrlMan을 통해 XLayer Manger를 얻습니다.
2. XLayer Style을 생성하여, 원하는 스타일을 설정합니다.
3. XLayer Manger의 NewXXXXX() 메소드를 이용하여 XLayer Object를 생성합니다.
4. 필요한 시점에 관련 오브젝트(Object)들을 제거합니다.
