AcDbRasterImage的setOrientation方法问题望指教

illuminiti 发表于 2011-12-20 14:31:58

AcDbRasterImage * pRasterImage = new AcDbRasterImage;
errorStatus = pRasterImage->setImageDefId(imageDefObjectId);
Adesk::Boolean returnValue;
AcGePoint3dorigin (4, 3, 0);
AcGeVector3d u(15, 0, 0),
v(0, 5, 0);
returnValue = pRasterImage->setOrientation(origin,u,v);
调试到returnValue为什么返回值总是 0？
这个方法该怎么用？有什么前提条件吗？
望指点谢谢！
