CAD交互绘制批注（网页版）

js中实现代码说明：

动态拖放时的绘制事件：

function DynWorldDrawComment( 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");

    // 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 = curPt;

    comment.Position = curPt;

    pWorldDraw.TextStyle = "MyCommentFont";

    // 动态绘制.

    pWorldDraw.DrawEntity(comment);

}

动态绘制文字：

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 DoComment() {

    // 出来一个对象，让用户输入文字.

    var winWidth = 440;

    var winHeight = 140;

    var winLeft = (screen.width - winWidth) / 2;

    var winTop = (screen.height - winHeight) / 2 - 20;

    var str = 'dialogHeight:' + winHeight + 'px;dialogWidth:' + winWidth + 'px;dialogTop:' + winTop + 'px;dialogLeft:' + winLeft + 'px;resizable:yes;center:yes;status:no;'

    var rt = window.showModalDialog("Gettext.htm?tmp=" + Math.random(), "输入文字", str);

    var txt;

    if (typeof (rt) == "undefined") {

        return;

    } else {

        var arr = rt.split(",");

        txt = arr[0];

    }

    // 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";

    // 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", 100);

    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 = 4;

    }

}
