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。
