CAD交互绘制云线批注（网页版）

js中实现代码说明：

动态拖放时的绘制事件：

function DoDynWorldDrawFun(dX,dY,pWorldDraw,pData) {

    //自定义实体的GUID标识符

    var sGuid = pData.Guid;

    //设置自定义事件的返回值

    mxOcx.SetEventRet(0);

    var curPt = mxOcx.NewPoint();

    curPt.x = dX;

    curPt.y = dY;

    if (sGuid == "DrawCircle") {

    var pt1 = pData.GetPoint("pt1");

    var dR = curPt.DistanceTo(pt1) * 0.5;

    var vec = curPt.SumVector(pt1);

    vec.Mult(0.5);

    pt1.Add(vec);

    pWorldDraw.DrawCircle(pt1.x, pt1.y, dR);

}

}

动态拖放时的绘制事件：

function  DynWorldDrawComment2( pCustomEntity,pWorldDraw,  curPt) {

    // 得到绘制参数.

    var sText = pCustomEntity.GetString("Text");

    var dTextHeight = pCustomEntity.GetDouble("TextHeight");

    var iEdgeNumber = pCustomEntity.GetLong("EdgeNumber");

    var dShapRadius = pCustomEntity.GetDouble("ShapRadius");

    var  basePoint = pCustomEntity.GetPoint("BasePoint");

    // 创建一个批注对象.

    var comment = mxOcx.NewEntity("IMxDrawComment");

    comment.Text        = sText;

    comment.TextHeight  = dTextHeight;

    comment.EdgeNumber  = iEdgeNumber;

    comment.ShapRadius  = dShapRadius;

    comment.basePoint   = basePoint;

    comment.Position = curPt;

    // 设置文字样式。

    pWorldDraw.TextStyle = "MyCommentFont";

    // 动态绘制.

    pWorldDraw.DrawEntity(comment);

}

动态绘制文字：

function ExplodeFun(pCustomEntity, pWorldDraw, txt) {

    var sGuid = pCustomEntity.Guid;

    if (sGuid == "TestMxCustomEntity1") {

        if (!pCustomEntity.IsHave("First"))

            return;

        var stp = pCustomEntity.GetPoint("First");

        var ept = pCustomEntity.GetPoint("BasePoint");

        var dimpt = pCustomEntity.GetPoint("DimPoint");

        var txt = pCustomEntity.GetString("Text");

        var textH = pCustomEntity.GetDouble("TextHeight");

        var edgeNum = pCustomEntity.GetLong("EdgeNumber");

        var shapRadius = pCustomEntity.GetDouble("ShapRadius");

        var isCircle = pCustomEntity.GetLong("isCircle");

        var comment = mxOcx.NewEntity("IMxDrawComment");

        comment.Text = txt;

        comment.TextHeight = textH;

        comment.EdgeNumber = edgeNum;

        comment.ShapRadius = shapRadius;

        comment.basePoint = ept;

        comment.Position = dimpt;

        pWorldDraw.TextStyle = "MyCommentFont";

        // 动态绘制.

        pWorldDraw.DrawEntity(comment);

        // 绘制矩形框.

        if (isCircle) {

            var dR = stp.DistanceTo(ept) * 0.5;

            var vec = stp.SumVector(ept);

            vec.Mult(0.5);

            ept.Add(vec);

            pWorldDraw.DrawCircle(ept.x, ept.y, dR);

        }

        else {

            pWorldDraw.DrawLine(stp.x, stp.y, stp.x, ept.y);

            pWorldDraw.DrawLine(stp.x, ept.y, ept.x, ept.y);

            pWorldDraw.DrawLine(ept.x, ept.y, ept.x, stp.y);

            pWorldDraw.DrawLine(ept.x, stp.y, stp.x, stp.y);

        }

        mxOcx.SetEventRet(1);

    }

}

动态绘制文字：

function DoCloudLineComment() {

    var param = mxOcx.NewResbuf();

    param.AddString("");

    param.AddDouble(100);

    var ret = mxOcx.CallEx("Mx_ShowMTextDialog", param);

    if (ret.AtString(0) != "Ok") {

        return;

    }

    var txt = ret.AtString(1);

    var txtH = ret.AtDouble(2);

    var txtColorIndex = ret.AtLong(3);

    // 加入换行操作符\\P

    //txt = txt + "\\PTEST";

    // 创建一个文字样式,用于批注文字字体.

    mxOcx.AddTextStyle2("MyCommentFont", "黑体", 0.7);

    // 创建一个与用户交互取点的对象。

    var getPt = mxOcx.NewComObject("IMxDrawUiPrPoint");

    getPt.message = "输入标注插入基点";

    // 设置动态绘制参数.

    var spDrawData = getPt.InitUserDraw("DrawComment");

    spDrawData.SetString("Text", txt);

    spDrawData.SetDouble("TextHeight", txtH);

    spDrawData.SetLong("EdgeNumber", 0);

    spDrawData.SetDouble("ShapRadius", 300);

    // 开始取第一个点。

    if (getPt.go() != 1)

        return;

    // 创建一个与用户交互取点的对象。

    var getSecondPt = mxOcx.NewComObject("IMxDrawUiPrPoint");

    getSecondPt.message = "输入标注位置点";

    getSecondPt.basePoint = getPt.value();

    getSecondPt.setUseBasePt(false);

    spDrawData = getSecondPt.InitUserDraw("DrawComment2");

    // 设置动态绘制参数.

    spDrawData.SetPoint("BasePoint", getPt.value());

    spDrawData.SetString("Text", txt);

    spDrawData.SetDouble("TextHeight", txtH);

    spDrawData.SetLong("EdgeNumber", 0);

    spDrawData.SetDouble("ShapRadius", 300);

    // 开始取第二个点。

    if (getSecondPt.go() != 1)

        return;

    var ret = spDrawData.Draw();

    // 设置绘制的批注文字样式。

    for (var i = 0; i < ret.Count; i++) {

        var ent = ret.AtObject(i);

        ent.TextStyle = "MyCommentFont";

        ent.colorIndex = txtColorIndex;

        if(ent.ObjectName == "McDbComment")

        {

            ent.BoundingBoxType = 4;

            ent.ArrowType = 2;

            ent.ShapRadius = 40;

        }

    }

}
