CAD參數繪制直線（網頁版）

用戶可以在CAD控件視區任意位置繪制直線。

主要用到函數說明：

_DMxDrawX::DrawLine

繪制一個直線。詳細說明如下：

js中實現代碼說明：

function?DrawLine()?{????
//清空當前顯示內容????
mxOcx.NewFile();????
//把顏色改回黑白色????
mxOcx.DrawCADColorIndex?=?0;????
//把線型改成實線????
mxOcx.LineType?=?"";????
//設置線寬?4????
mxOcx.LineWidth?=?0;????
//創建一個圖層,名為"LineLayer"???
?mxOcx.AddLayer("LineLayer");???
??//設置當前圖層為"LineLayer"????
??mxOcx.LayerName?=?"LineLayer";????
??//?直接繪制一個實線????
??//?參數一直線的開始點x坐標，參數二直線的開始點y坐標，參數三直線的結束點x坐標，參數四直線的結束點y坐標????
??mxOcx.DrawLine(0,?0,?100,?0);????
??//?繪制一個實斜線????
??mxOcx.DrawLine(200,?0,?300,?100);???
???//----------------------------------------------------------------------------------------------------------????
???//繪制一個虛線????
???//定義虛線數據據,"MyLineType"是線型名，"6,-8"是虛線的一個單位定義，6是實線長，-8是空格長。????
???mxOcx.AddLinetype("MyLineType",?"6,-10");????
???//設計當前線型為"MyLineType"????
???mxOcx.LineType?=?"MyLineType";????
???//?繪制一個虛線????
???mxOcx.DrawLine(0,?30,?100,?30);????
???//?繪制一個斜虛線????
???mxOcx.DrawLine(200,?30,?300,?130);????
???//---------------------------------------------------------------------------------------------------------???
????//?修改繪線的顏色為?16711680(藍色),??16711680轉成16進制是0xFF?00?00,其中，FF是藍色，00是綠色，第個二00是紅色。??
??????mxOcx.DrawCADColor?=?16711680;????
??????//?繪制一個藍色的虛線????
??????mxOcx.DrawLine(0,?60,?100,?60);???

??????????//繪制一個帶寬度的直線。????
??????????mxOcx.DrawLine(0,?90,?100,?90);????
??????????//?繪制一個帶寬度的斜線????
??????????mxOcx.DrawLine(200,?90,?300,?190);????
??????????//---------------------------------------------------------------------------------------------------------
??????????//繪制一個點劃線虛線????
??????????mxOcx.AddLinetype("MyLineType2",?"10,-2,3,-2");????
??????????//把線型改點劃線????mxOcx.LineType?=?"MyLineType2";????
??????????//?修改繪線的顏色為?255(紅色),??255轉成16進制是0x00?00?FF,其中，00是藍色，第個二00是綠色，FF是紅色。????
??????????mxOcx.DrawCADColor?=?255;????
??????????//繪制一個帶寬度的紅色點劃線。????
??????????mxOcx.DrawLine(0,?120,?100,?120);????
??????????//?繪制一個帶寬度紅色點劃斜線????
??????????mxOcx.DrawLine(200,?120,?300,?220);????
??????????//---------------------------------------------------------------------------------------------------------
??????????????//增加一個帶有形的線型???
???????????????mxOcx.AddTextStyle1("MyLineTypeTextStyle",?"txt.shx",?"hztxt.shx",?1);????
