VB.NET编程语言可以帮助开发人员实现许多特定的功能。比如像今天我们为大家介绍的VB.NET文字特效的实现,就可以通过VB.NET进行简单的操作即可实现。下面就让我们来看看各种特效的实现办法。#t#
(1)新建一个名为“DrawFont”的项目,然后在窗体设计器中,添加4个Button按钮,对窗体和各个控件设置其属性如下:
- Form1的Text属性:文字特效 BackGroupImage
属性:C:\windows\Web\Wallpaper\Bliss.jpg - Button1的name属性:btnSD Text属性:3D文字
- Button1的name属性:btnYY Text属性:阴影文字
- Button1的name属性:btnJB Text属性:渐变文字
- Button1的name属性:btnTA Text属性:图案文字
(2)为控件添加相应的代码,完整的VB.NET文字特效代码如下:
- Imports System.Drawing
- Imports System.Drawing.Drawing2D
- Public Class Form1
- Inherits System.Windows.Forms.Form
- Private flag As Integer
- Private Sub Form1_Paint(ByVal sender
As System.Object, ByVal e As System.
Windows.Forms.PaintEventArgs)
Handles MyBase.Paint- Dim fntText = New Font("隶书", 40)
- Dim g As Graphics = e.Graphics
- Dim brB, brF As Brush
- Dim bm As ImageImage = Image.FromFile
("D:\WINDOWS\Web\Wallpaper\20.jpg")- Dim i As Integer
- Dim p1, p2 As Point
- p1.X = 20
- p1.Y = 20
- p2.X = 200
- p2.Y = 20
- Select Case flag
- Case 1
- brB = New SolidBrush(Color.FromArgb
(100, Color.Black))- brF = New SolidBrush(Color.Red)
- For i = 1 To 10
- g.DrawString("Visual Basic.Net",
fntText, brB, p1.X + i, p1.Y + i)- g.DrawString("程序设计", fntText,
brB, p1.X + 150 + i, p1.Y + 50 + i)- Next
- g.DrawString("Visual Basic.Net",
fntText, brB, p1.X, p1.Y)- g.DrawString("程序设计", fntText,
brB, p1.X + 150, p1.Y + 50)
- Case 2
- brB = New SolidBrush(Color.
FromArgb(120, Color.Black))- brF = New SolidBrush(Color.Red)
- g.DrawString("Visual Basic.Net",
fntText, brB, p1.X + 5, p1.Y + 5)- g.DrawString("程序设计", fntText,
brB, p1.X + 150 + 5, p1.Y + 50 + 5)- g.DrawString("Visual Basic.Net",
fntText, brB, p1.X, p1.Y)- g.DrawString("程序设计", fntText,
brB, p1.X + 150, p1.Y + 50)
- Case 3
- brF = New LinearGradientBrush
(p1, p2, Color.Red, Color.Yellow)- g.DrawString("Visual Basic.Net",
fntText, brF, p1.X, p1.Y)- g.DrawString("程序设计", fntText,
brF, p1.X + 150, p1.Y + 50)
- Case 4
- brF = New TextureBrush(bm)
- g.DrawString("Visual Basic.Net",
fntText, brF, p1.X, p1.Y)- g.DrawString("程序设计", fntText,
brF, p1.X + 150, p1.Y + 50)- End Select
- End Sub
- Private Sub btnSD_Click(ByVal
sender As System.Object, ByVal
e As System.EventArgs) Handles
btnSD.Click- flag = 1
- Me.Invalidate()
- End Sub
- Private Sub btnYY_Click(ByVal
sender As System.Object, ByVal e
As System.EventArgs) Handles btnYY.Click- flag = 2
- Me.Invalidate()
- End Sub
- Private Sub btnJB_Click(ByVal
sender As System.Object, ByVal
e As System.EventArgs) Handles btnJB.Click- flag = 3
- Me.Invalidate()
- End Sub
- Private Sub btnTA_Click(ByVal sender
As System.Object, ByVal e As System.
EventArgs) Handles btnTA.Click- flag = 4
- Me.Invalidate()
- End Sub
- End Class
(3)VB.NET文字特效程序说明:
程序开头要用到两个命名空间,所以加上两行代码:
- Imports System.Drawing
- Imports System.Drawing.
Drawing2D
其次为窗体添加Paint事件,VB.NET文字特效的3D,阴影,渐变,图案效果都是在窗体的Paint事件中实现的,所谓窗体的Paint事件,说的简单点就是一个画图事件。
