<P>呵呵,绘制的代码如下</P>
<P> <TABLE> <TR> <TD class=postvalue> </TD></TR> <TR> <TH> </TH> <TD><PRE>Sub EllipseRotate() Dim pEnv As IEnvelope Set pEnv = New Envelope With pEnv .XMin = -1 .YMin = -2 .XMax = 1 .YMax = 2 End With Dim pConsEllArc As IConstructEllipticArc Set pConsEllArc = New EllipticArc pConsEllArc.ConstructEnvelope pEnv Dim pEllArc As IEllipticArc Set pEllArc = pConsEllArc Dim pCurve As ICurve Set pCurve = pEllArc Debug.Print Dim dMajor As Double, dMinor As Double, dRatio As Double pEllArc.GetAxes dMajor, dMinor, dRatio Debug.Print "before: major " ; dMajor; ", Minor: " ; dMinor Debug.Print "Axis Angle: " ; Atn(pCurve.FromPoint.Y / pCurve.FromPoint.X) * 180 / PI Dim pRotPoint As IPoint Set pRotPoint = New Point pRotPoint.X = Rnd * 100 pRotPoint.Y = Rnd * 100 Dim pTrans2D As ITransform2D Set pTrans2D = pEllArc pTrans2D.Rotate pRotPoint, Rnd * PI pEllArc.GetAxes dMajor, dMinor, dRatio Debug.Print "after: major " ; dMajor; ", Minor: " ; dMinor Debug.Print "Axis Angle: " ; Atn(pCurve.FromPoint.Y / pCurve.FromPoint.X) * 180 / PI End Sub </PRE><PRE>不过如果要保存在shapefile或者数据库中,你需要启动编辑</PRE><PRE><PRE>'开始 the edit session '... '... '创建椭圆(ellipse),可以使用上面的过程代码'... '... 这个放在pTrans2D.Rotate pRotPoint, Rnd * PI的后面 Dim pFeat As IFeature Set pFeat = pFClass.CreateFeature Set pFeat.Shape = pEllArc pFeat.Store '停止 edit operation '... '...</PRE> </PRE></TD></TR></TABLE></P> |

<P>我不赞成上面的说法,AE9.2本来提供了强大的二次开发工具,为什么还要一点点的开发代码。现在就可利用下列代码实现基本绘图:</P>
<P>/创建绘图工具板并添加到工具条中<BR> //////////////////////////////////////////////////////////////////////////<BR> m_ToolbarPDraw = new ToolbarPaletteClass();</P> <P> m_ToolbarPDraw.AddItem("esriControls.ControlsEditingSketchTool", -1, -1);<BR> m_ToolbarPDraw.AddItem("esriControls.ControlsNewMarkerTool", -1, -1);<BR> m_ToolbarPDraw.AddItem("esriControls.ControlsNewLineTool", -1, -1);<BR> m_ToolbarPDraw.AddItem("esriControls.ControlsNewCurveTool", -1, -1);<BR> m_ToolbarPDraw.AddItem("esriControls.ControlsNewCircleTool", -1, -1);<BR> m_ToolbarPDraw.AddItem("esriControls.ControlsNewRectangleTool", -1, -1);<BR> m_ToolbarPDraw.AddItem("esriControls.ControlsNewPolygonTool", -1, -1);</P> <P>axToolbarControl1.AddItem(m_ToolbarPDraw, 0, -1, true, 0, esriCommandStyles.esriCommandStyleIconOnly);</P> |
