JPEG without loss: cut 2 pixel from the height of a pic

I'm trying to cut an horizontal line of 2 pixel from the height(from the bottom) of some images using these parameters:

Selecting only 1 pixel cutted from the bottom I get cutted a line of 2 pixel from the height and a line of 1 pixel cutted from the width! I don't know why this happens???

I need to cut images from 642x480 pixel to 640x480 pixel: how can i do?

Thanks!
