视口缩放

nym 发表于 2005-11-30 14:07:00

acedCommand(RTSTR, "Zoom", RTSTR, "Window", RTPOINT, dZoomMin,      RTPOINT, dZoomMax, RTNONE);
上面是我用command命令实现的视口缩放的功能，
请问如果不用command命令，该怎么做呢？
寻求帮助，谢谢！！！

应该发在arx版块:
void zoomWindow(AcGePoint3d &min, AcGePoint3d &max) {  // get the extents of the drawing  AcDbViewTableRecord view;
 AcGePoint2d max_2d (max, max);  AcGePoint2d min_2d (min, min);  // now set the view center point  view.setCenterPoint(min_2d + (max_2d - min_2d) / 2.0);  // now height and width of view  view.setHeight(max_2d - min_2d);  view.setWidth(max_2d - min_2d);  // set the view  acedSetCurrentView(&view, NULL);  // update the extents  acdbHostApplicationServices()->workingDatabase()->updateExt(TRUE); }
