为了减小我拥有的一些图像的大小,我想删除一些图像的白色填充。这个想法是,如果边界上有大的白色区域,那么可以裁剪这些区域以节省一些空间。
任何想法?
我使用了裁剪边框
Dim MinX As Integer = W : Dim MaxX As Integer = 0
Dim MinY As Integer = H : Dim MaxY As Integer = 0
Dim White As Integer = Color.White.ToArgb()
For x As Integer = 0 To W - 1
For y As Integer = 0 To H - 1
If Not Output.GetPixel(x, y).ToArgb() = White Then
MinX = Math.Min(MinX, x)
MaxX = Math.Max(MaxX, x)
MinY = Math.Min(MinY, y)
MaxY = Math.Max(MaxY, y)
End If
Next
