vb.net画矢量图的简单介绍

VB.NET中如何运用如下图的这种矢量图形？

你的方法是常用的方法了，除非你自己写GDI类或者用第三方控件了

用VB.NET绘制GDI图形

下面的例子通过重载Form 窗体的OnPaint()方法绘制GDI图形Protected Overrides Sub onpaint(ByVal e As System Windows Forms PaintEventArgs)注释 /////////////绘制任意直线Dim g As Graphics = e GraphicsDim mypen As Pen = New Pen(Color Red )g DrawLine(mypen )注释 /////////////绘制矩形(任意直线构成的封闭图形)Dim point As PointF = New PointF( F F)Dim point As PointF = New PointF( F F)Dim point As PointF = New PointF( F F)Dim point As PointF = New PointF( F F)Dim curvepoints As PointF() = {point point point point }g DrawPolygon(New Pen(Color Blue ) curvepoints)注释 ////////////文本表示Dim FFamily As FontFamily = New FontFamily( Arial )Dim font As Font = New Font(FFamily FontStyle Bold FontStyle Italic GraphicsUnit Pixel)Dim text As String = I love you! Dim solidbrush As SolidBrush = New SolidBrush(Color Red)Dim pr As PointF = New PointF( )e Graphics DrawString(text font solidbrush pr)注释 ////////////平面绘制Dim rec As RectangleF = New RectangleF( )g DrawPie(mypen rec )注释 ///////////封闭图形 应该是个圆g DrawClosedCurve(mypen curvepoints Drawing Drawing D FillMode Alternate)注释 ///////////大家自己试试看吧g DrawArc(mypen )g DrawCurve(mypen curvepoints)g DrawBezier(mypen )g DrawBeziers(mypen curvepoints)注释 //////////这可是一个圆Dim rec As RectangleF = New RectangleF( )g DrawEllipse(mypen rec )注释 //////////这是一个椭圆Dim rec As RectangleF = New RectangleF( )g DrawEllipse(mypen rec )End Sub 这些是我自己试验出来的 当然了 还有好多 我只是开了一个头 大家要是发现什么好东东 别忘了通知一下 ） lishixinzhi/Article/program/net/201311/11800

VB.net中如何画图？

VB.net与VB不同。

VB.net已经有专门绘图的类。

可以定义笔刷然后用Drawing类中的方法绘制。

Private Sub DrawEllipse()

Dim myPen As New System.Drawing.Pen(System.Drawing.Color.Red)

Dim formGraphics as System.Drawing.Graphics

formGraphics = Me.CreateGraphics()

formGraphics.DrawEllipse(myPen, New Rectangle(0,0,200,300))

myPen.Dispose()

formGraphics.Dispose()

End Sub

Private Sub DrawRectangle()

Dim myPen As New System.Drawing.Pen(System.Drawing.Color.Red)

Dim formGraphics as System.Drawing.Graphics

formGraphics = Me.CreateGraphics()

formGraphics.DrawRectangle(myPen, New Rectangle(0,0,200,300))

myPen.Dispose()

formGraphics.Dispose()

End Sub
