无聊, 就写了这个程序。
Imports System.Drawing
Module Module1
Const Src = "hello.bmp", Bg = "xing.bmp", Des = "love.bmp"
Dim SrcImg As Bitmap = Bitmap.FromFile(Src),
BgImg As Bitmap = Bitmap.FromFile(Bg),
DesImg As New Bitmap(SrcImg.Width, SrcImg.Height)
Sub Main()
For y = 0 To SrcImg.Height - 1
For x = 0 To SrcImg.Width - 1
Dim c = SrcImg.GetPixel(x, y)
Dim d = BgImg.GetPixel(x, y)
If c = Color.FromArgb(255, 0, 0, 0) Then
If d <> Color.FromArgb(255, 255, 255, 255) Then
DesImg.SetPixel(x, y, Color.DarkRed)
Else
DesImg.SetPixel(x, y, Color.DarkCyan)
End If
Else
DesImg.SetPixel(x, y, Color.White)
End If
'Debug.Print(c.ToString)
Next
Next
Dim g = Graphics.FromImage(DesImg)
g.DrawString("by Wandai twd2.me", New Font("微软雅黑", 8), Brushes.Brown, 25, 0)
g.DrawString("!", New Font("微软雅黑", 8), Brushes.Brown, 40, 149)
DesImg.Save(Des)
Console.WriteLine("done.")
Console.ReadKey()
End Sub
End Module

不解释。


不错!
