AcDbViewport::setWidth Function Acad::ErrorStatus

setWidth(

double unnamed);

unnamed Input viewport width

This function sets width to be the width of the viewport entity's window in drawing units. This is the width in paperspace of the viewport itself, not the width of the model space view within the viewport.

Returns Acad::eOk if successful.

The viewport height is used for DXF group code 40.


AcDbViewport::setHeight Function

Acad::ErrorStatus

setHeight(

double unnamed);

unnamed

Input height for the viewport window

This function sets the viewport's window to be height drawing units high.
Returns Acad::eOk if successful.
The viewport height is used for DXF group code 41.

AcDbViewport::setWidth Function Acad::ErrorStatus

setWidth(

view.setCenterPoint(PtCenter);
view.setHeight(5.0);
view.setWidth(5.0);

这样写的，命令执行完也不变，需要更新什么东西吗

网上找的代码

double scale;

    if (ads_getreal(_T("Enter scale:"), &scale) != RTNORM) goto END1;

    AcDbObjectId idVp;

    if ((idVp=acdbGetCurViewportObjectId())==AcDbObjectId::kNull)
        {
                ads_printf(_T("No current viewport. (tilemode=1?)\n"));
   
                goto END1;
    }

    AcDbViewport* pVp;

    Acad::ErrorStatus es;

    if((es=acdbOpenObject(pVp,idVp,AcDb::kForWrite))==Acad::eOk)
        {
                double height = pVp->height();
     
                AcDbViewTableRecord view;
     
                AcGePoint2d max;

                max.x = 5.0;
       
                max.y = 5.0;
     
                view.setCenterPoint(max);
   
                view.setHeight(5.0);
   
                view.setWidth(5.0);

                if ((es=acedSetCurrentView( &view, pVp))==Acad::eOk)
                {
                        ads_printf(_T("Scale set to %f.\n",scale));
       
                }else
                {
                        ads_printf(_T("Failed to set scale.\n"));
                }

                pVp->close();
    }

    if (es!=Acad::eOk) ads_printf(_T("ERROR: es = %s\n"),acadErrorStatusText(es));

double scale;

你这个代码是设置视口的缩放的，不是设置视口的宽和高。你要设置AcDbViewPort的宽和高。
