Convert Texture2D to Image emgu CV - fast way

Question

Hi all,

I'm trying to convert a texture2D to an emgu CV Image. I want a fast way to do it, without access each pixel individually (for loop). I'm trying to use Marshal.copy or some memory access.

If I know how color32[] are place in memory it would be great.

Thanks in advance.

I'm doing something like this:

 Image<Bgr, byte> output;

 MemoryStream m = new MemoryStream(input.EncodeToPNG());
 Image<Rgba, byte> temp = new Image<Rgba, byte>(input.width, input.height);

 temp.Bitmap = new Bitmap(m);

 output = temp.Convert<Bgr, byte>();

Hope this helps.
