MxDrawXCustomFunction::ExApp

图纸剪切

IDL

static BOOL ExApp_CutDwg(IN DOUBLE dX1, IN DOUBLE IN dY1, IN DOUBLE dX2, IN DOUBLE IN dY2, IN LPCTSTR pszFileName, IN DOUBLE dPdfPaperWidth = 297, IN DOUBLE dPdfPaperHeight = 210);

参数

参数	说明
IN DOUBLE dX1	保存范围的左下角位置X值
IN DOUBLE IN dY1	保存范围的左下角位置Y值
IN DOUBLE dX2	保存范围的右上角位置X值
IN DOUBLE IN dY2	保存范围的右上角位置Y值
IN DOUBLE dPdfPaperWidth = 297	转pdf时，图纸宽度,默认297
IN DOUBLE dPdfPaperHeight = 210	转pdf时，图纸高度,默认210
sFile	保存的文件名

成功返回true通过pRet->AtLong(1)得到。

备注

例如: VB代码

      Set mxUtility = New MxDrawXLib.MxDrawUtility

      Dim getPt As MxDrawXLib.MxDrawPoint

      Set getPt = mxUtility.GetPoint(, Chr(13) + Chr(10) + "输入矩形框左下角点:")

      If (getPt Is Nothing) Then
        Exit Sub
      End If

      Set param = New MxDrawXLib.MxDrawResbuf
      param.AddDouble getPt.x, -10
      param.AddDouble getPt.y, -10


      Set retParam = MxDrawX1.CallEx("Mx_GetCorner", param)
      If retParam.AtString(0) = "Ok" Then

            Set param2 = New MxDrawXLib.MxDrawResbuf
            param2.AddDouble retParam.AtDouble(1)
            param2.AddDouble retParam.AtDouble(2)
            param2.AddDouble getPt.x
            param2.AddDouble getPt.y
            param2.AddString "c:11111.dwg"

            MxDrawX1.CallEx "ExApp_CutDwg", param2

      End If

例如: C#代码

 private void CutDwgFun()
    {
        MxDrawUtility mxUtility = new MxDrawUtility();

        MxDrawPoint pt = (MxDrawPoint)(mxUtility.GetPoint(null,"n 输入剪切矩形框左下角点:"));

        if (pt == null)
        {
          MessageBox.Show("用户取消..");
          return;
        }

        MxDrawResbuf param = new MxDrawResbuf();
        param.AddDouble(pt.x);
        param.AddDouble(pt.y);

        MxDrawResbuf retParam = (MxDrawResbuf)axMxDrawX1.CallEx("Mx_GetCorner", param);

        if(retParam.AtString(0) == "Ok")
        {
            SaveFileDialog sfd = new SaveFileDialog();
            sfd.Filter = "dwg 文件(*.dwg)|*.dwg";

            if (sfd.ShowDialog() != DialogResult.OK)
            {
                return;
            }

            MxDrawResbuf param2 = new MxDrawResbuf();
            param2.AddDouble(retParam.AtDouble(1));
            param2.AddDouble(retParam.AtDouble(2));
            param2.AddDouble(pt.x);
            param2.AddDouble(pt.y);
            param2.AddString(sfd.FileName);

            MxDrawResbuf ret;
            ret = (MxDrawResbuf)axMxDrawX1.CallEx("ExApp_CutDwg", param2);
            if(ret.AtString(0) == "Ok")
            {
                MessageBox.Show("剪切成功");
            }
            else
            {
                MessageBox.Show("剪切失败");
            }
        }

    }

例如: 剪切图纸，转成pdf,并指定pdf图纸的宽高.

            MxDrawResbuf param2 = new MxDrawResbuf();
            param2.AddDouble(retParam.AtDouble(1));
            param2.AddDouble(retParam.AtDouble(2));
            param2.AddDouble(pt.x);
            param2.AddDouble(pt.y);
     
            // 转pdf
            param2.AddString("I:\111.pdf");

            // 转pdf时，图纸宽度
            param2.AddDouble(500);
            param2.AddDouble(1000);
         

            MxDrawResbuf ret;
            ret = (MxDrawResbuf)axMxDrawX1.CallEx("ExApp_CutDwg", param2);
