翻转图像会导致AForge.net使用大量RAM / CPU

Question

嘿所有我想弄清楚为什么当我翻转图像时它会使用大量的RAM和CPU（它的四核i7）

我使用此代码：

Dim filter As New RotateBilinear(180, True)
image = Filter.Apply(image)

  If bIsToRecord Then
        If writer Is Nothing Then
            Dim [date] As DateTime = DateTime.Now
            Dim fileName As [String] = [String].Format("{0},{1}.avi",[date].Minute, [date].Second)

            Try
                OpenWriter(fileName, image.Width, image.Height)
            Catch ex As Exception
                If writer IsNot Nothing Then
                    writer.Dispose()
                    writer = Nothing
                End If
            End Try
        End If

        Try
            If radioButton1.Checked Then
                writer.AddFrame(image)
            Else
                mVideoFileWriter.WriteVideoFrame(image)
            End If
        Catch ex As Exception
            System.Diagnostics.Trace.WriteLine(ex.ToString())
        End Try
    End If

这是没有翻转图像

随着翻转...

每次截图持续30秒。

导致这种情况的原因是什么？
