用VB制作三维字体

在用VB制作软件封面和界面时经常要用到三维字体，一般的方法是先用专门的软件（如Xara3d等）制作出三维字体的图片，然后再用图片框等控件显示出来。这样虽然简单，但其缺点有二：一是要额外增加控件和图片，这样势必会增加程序的大小；二是在VB中图片的加载速度不敢恭维。如能用VB直接编程制作出三维字体，岂不美哉！以下是本人的一点“小技”，请笑纳！

先在VB中新建一个“工程”，然后在窗体上放置四个Command。以下是源程序：

先声明如下“通用变量”:

Dim posx, posy As Integer '文字的显示位置

Dim txtwidth As Integer '文字轮廓宽度

Dim str As String '欲显示的文字

Private Sub Command1_Click() '显示凸起三维文字

Dim i As Integer

str = "显示凸起三维文字"

Me.Cls

Me.ForeColor = RGB(255, 255, 255)

For i = 1 To txtwidth

Me.CurrentX = posx - i

Me.CurrentY = posy - i

Me.Print str

Next i

Me.ForeColor = RGB(0, 0, 0)

For i = 1 To txtwidth

Me.CurrentX = posx + i

Me.CurrentY = posy + i

Me.Print str

Next i

Me.ForeColor = RGB(0, 0, 255)

Me.CurrentX = posx

Me.CurrentY = posy

Me.Print str

End Sub

Private Sub Command2_Click() '显示凹陷三维文字

Dim i As Integer

str = "显示凹陷三维文字"

Me.Cls

Me.ForeColor = RGB(0, 0, 0)

For i = 1 To txtwidth

Me.CurrentX = posx - i

Me.CurrentY = posy - i

Me.Print str

Next i

Me.ForeColor = RGB(255, 255, 255)

For i = 1 To txtwidth

Me.CurrentX = posx + i

Me.CurrentY = posy + i

Me.Print str

Next i

Me.ForeColor = RGB(0, 0, 255)

Me.CurrentX = posx

Me.CurrentY = posy

Me.Print str

End Sub

Private Sub Command3_Click() '显示阴影三维文字

str = "显示阴影三维文字"

Me.Cls

Me.ForeColor = RGB(100, 100, 100)

Me.CurrentX = posx + txtwidth

Me.CurrentY = posy + txtwidth

Me.Print str

Me.ForeColor = RGB(0, 0, 255)

Me.CurrentX = posx

Me.CurrentY = posy

Me.Print str

End Sub

Private Sub Command4_Click() '显示倾斜三维文字

Dim i As Integer

str = "显示倾斜三维文字"

Me.Cls

Me.ForeColor = RGB(100, 100, 100)

For i = 1 To txtwidth

Me.CurrentX = x + i

Me.CurrentY = y + i

Me.Print str

Next i

Me.ForeColor = RGB(0, 0, 255)

Me.CurrentX = posx

Me.CurrentY = posy

Me.Print str

End Sub

Private Sub Form_Load()

posx = 100

posy = 100

txtwidth = 50

Me.FontSize = 30

End Sub

以上程序在win98/vb6.0/233下调试通过。
