Is this a bug?

Hi guys,

I am implementing "Quad Warping" in order to do fat/skinny face effect. Quad Warping is quite much work but I don't know if there is any other options to do the face effect things.

Anyways, I sort of completed writing code but the result image seems not right and I wonder if it is a bug in OpenCV. Please see the image below:

Can you guys notice the pixels have been rotated up even though size of resulting rectangle is right? Is this a bug? or a right attribute of WarpPerspective() ?
