|
www.mxdraw.com
|
|
|
返回光栅图形的位置参数
[helpstring("method GetOrientation")]
HRESULT GetOrientation([out] IMxDrawPoint** origin, [out] IMxDrawVector3d** uCorner, [out] IMxDrawVector3d** vOnPlane);|
参数 |
说明 |
|
[out] IMxDrawPoint** origin |
光栅图形的插入点 |
|
[out] IMxDrawVector3d** uCorner |
光栅图的宽度方向显示向量，用于确定光栅图的宽度，和旋转角度 |
|
[out] IMxDrawVector3d** vOnPlane |
光栅图的高度方向显示向量，该向量必须垂直vConer，确定光栅图的高度 |
例如: C#
MxDrawEntity ent = (MxDrawEntity)axMxDrawX1.GetEntity("image");
if (ent == null)
return;
if (!(ent is MxDrawRasterImage) )
{
return;
}
MxDrawRasterImage image = (MxDrawRasterImage)ent;
MxDrawPoint Origin;
MxDrawVector3d uCorner;
MxDrawVector3d vOnPlane;
image.GetOrientation(out Origin, out uCorner, out vOnPlane);
Double dW = uCorner.Length();
Double dH = vOnPlane.Length();
