Telerik지도와 WMS를 통합합니다. Telerik 포럼에서 줌이 훌륭하게 작동 할 때까지 올바르게 작동하는 몇 가지 샘플 코드를 발견했으며 MaxX와 MinX가 동일한 값을 반환하고 Miny와 Maxy가 동일한 값을 반환하기 때문에 계산을 수행하는 것은 올바르지 않습니다. QuadKey, BBox, Tilex, Tiley ...의 기능을 이해하지 못하고 코드를 수정하지 않았습니다. 여기 포럼에 제공된 샘플 코드를 telerik에 넣습니다. 누군가이 오류의 위치를 확인하십시오. 줌이 높을 때 나도 같은 값을 반환Telerik지도 + WMS

기능은 다음과 같습니다 ConvertYToLatitude 및 ConvertXToLongitude. 비록 제가 X1과 X2에 제공하는 값이 다릅니다. 그리고 Y1과 Y2의 값도 다릅니다.
10 진수 및 2 진수로 문제가 될 수 있는지 알 수 없습니다.
