Comment (by ami_stuff):

 Please view 422_odd.jpg and out.bmp at the same time im IMDisplay
 (ImageMagick). You will notice a one-pixel-wide vertical line (from top to
 bottom of the image) in the output bmp file after the last person on the
 image (right side). This line does not exist in loaded jpg image.

 It's easier to spot it in IrfanView where the line have gray color (not
 the color of the ground).
