EmguCV Image size different from Image.Data size

I copy a part of an image to a new one:

bigImage.ROI = SomeRectangle;
Emgu.CV.Image<Emgu.CV.Structure.Rgb, byte> roiImage = bigImage.Copy();

Now roiImage.Cols==roiImage.Width==1 and roiImage.Rows==roiImage.Height==106; however size of roiImage.Data is [106,4,3]. So Width of image is not equal to the second dimension of the data.

Why does that occur?

EmguCV requires each row of your image to be aligned by 4 bytes to improve efficiency in fetching data.
