Question

怎样把文字做成图片？

Answer 1

只要将VB窗口内的需要部分保存成图片文件就可以了
要用到API函数的：
Private Type POINTAPI
x As Long
y As Long
End Type
Private Declare Function BitBlt Lib "gdi32" (ByVal hDestDC As Long, ByVal x As Long, ByVal y As Long, ByVal nWidth As Long, ByVal nHeight As Long, ByVal hSrcDC As Long, ByVal xSrc As Long, ByVal ySrc As Long, ByVal dwRop As Long) As Long
Private Declare Function GetDC Lib "user32" (ByVal hwnd As Long) As Long
Private Declare Function GetCursorPos Lib "user32" (lpPoint As POINTAPI) As Long
Private Declare Function DrawIcon Lib "user32" (ByVal hdc As Long, ByVal x As Long, ByVal y As Long, ByVal hIcon As Long) As Long
Private Declare Function ReleaseDC Lib "user32" (ByVal hwnd As Long, ByVal hdc As Long) As Long

Private Sub Command1_Click()
Dim hdc As Long
Dim sw As Integer
Dim sh As Integer
Dim CurPos As POINTAPI
Dim Cur As Long
Me.Hide
DoEvents
Picture1.AutoRedraw = True
hdc = GetDC(0)
GetCursorPos CurPos
Cur = GetCursor
Picture1.Width = Screen.Width
Picture1.Height = Screen.Height
sw = Screen.Width / Screen.TwipsPerPixelX
sh = Screen.Height / Screen.TwipsPerPixelY
BitBlt Picture1.hdc, 0, 0, sw, sh, hdc, 0, 0, vbSrcCopy
Me.Show
DrawIcon Picture1.hdc, CurPos.x - 10, CurPos.y - 10, Cur
ReleaseDC 0, hdc
Picture1.AutoRedraw = False

以下放到模块里：
Option Explicit

Type RECT_Type

left As Long
top As Long
right As Long
bottom As Long

End Type

'The following declare statements are case sensitive.

Declare Function GetActiveWindow Lib "User32" () As Long

ByVal hdc As Long) As Long
Declare Function DeleteDC Lib "Gdi32" (ByVal hdc As Long) As Long
Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)

Global Const SRCCOPY = &HCC0020
Global Const CF_BITMAP = 2

Function ScreenDump()
Dim AccessHwnd As Long, DeskHwnd As Long
Dim hdc As Long
Dim hdcMem As Long
Dim rect As RECT_Type
Dim junk As Long
Dim fwidth As Long, fheight As Long
Dim hBitmap As Long

' DoCmd.Hourglass True

'---------------------------------------------------

DoEvents
DeskHwnd = GetDesktopWindow()

'---------------------------------------------------
' Get screen coordinates of Microsoft Access
'---------------------------------------------------
Call GetWindowRect(AccessHwnd, rect)
fwidth = rect.right - rect.left
fheight = rect.bottom - rect.top

'---------------------------------------------------
' Get the device context of Desktop and allocate memory
'---------------------------------------------------
hdc = GetDC(DeskHwnd)
hdcMem = CreateCompatibleDC(hdc)
hBitmap = CreateCompatibleBitmap(hdc, fwidth, fheight)

If hBitmap <> 0 Then
junk = SelectObject(hdcMem, hBitmap)

'---------------------------------------------
' Copy the Desktop bitmap to memory location
' based on Microsoft Access coordinates.
'---------------------------------------------
junk = BitBlt(hdcMem, 0, 0, fwidth, fheight, hdc, rect.left, _
rect.top, SRCCOPY)

'---------------------------------------------
' Set up the Clipboard and copy bitmap
'---------------------------------------------
junk = OpenClipboard(DeskHwnd)
junk = EmptyClipboard()
junk = SetClipboardData(CF_BITMAP, hBitmap)
junk = CloseClipboard()
End If

'---------------------------------------------
' Clean up handles
'---------------------------------------------
junk = DeleteDC(hdcMem)
junk = ReleaseDC(DeskHwnd, hdc)

' DoCmd.Hourglass False

End Function

下面分二步介绍如何把VB得部分窗体生成图片（清晰的）

一、建立一个模块，复制下面代码:

'=============模块开始=================
Option Explicit

Private Type PALETTEENTRY
peRed As Byte
peGreen As Byte
peBlue As Byte
peFlags As Byte
End Type

Private Type LOGPALETTE
palVersion As Integer
palNumEntries As Integer
palPalEntry(255) As PALETTEENTRY
End Type

Private Type GUID
Data1 As Long
Data2 As Integer
Data3 As Integer
Data4(7) As Byte
End Type

Private Const RASTERCAPS As Long = 38
Private Const RC_PALETTE As Long = &H100
Private Const SIZEPALETTE As Long = 104

Private Type RECT
Left As Long
Top As Long
Right As Long
Bottom As Long
End Type

Private Declare Function CreateCompatibleDC Lib "GDI32" (ByVal hDC As Long) As Long

Answer 2

可以用qq截图也行，按ctrl+a后，在一个地方框起来——按就截图工具栏上的A后打上字——保存就ok了

Answer 3

楼主
ps么？会的话，你可以新建一个空白的文档，然后点文字工具
到那里写你需要的字就可以
不会的话
，就用截图也行啊

Answer 4

用ps
写好字以后直接栅格化就可以转换成图片的形式

Answer 5

右击文字图层，选择删除格式化
