A negative height in the BMP header means that the scanlines are
stored from top-to-bottom (rather than bottom-to-top, which is what
you get if you put a positive height). I don't believe that this is a
bug.

I am not sure where should I post, but I think, I have found a bug in
ImageIO framework.
I am using this framework to save images. Noticed (using 'file'
command in terminal) that BMP images, created with ImageIO has
negative height (PC bitmap data, Windows 3.x format, 1200 x -900 x
24). Such images causes open problems on Windows.
The same happens when saving images in BMP format with Apple Preview
(I am sure it uses the same ImageIO).
