视口缩放

nym

  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[X], max[Y]);
 AcGePoint2d min_2d (min[X], min[Y]);
 // 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[Y] - min_2d[Y]);
 view.setWidth(max_2d[X] - min_2d[X]);
 // set the view
 acedSetCurrentView(&view, NULL);
 // update the extents
 acdbHostApplicationServices()->workingDatabase()->updateExt(TRUE);
}
