No. If you try a small sample you can see it. I just
tried it with a 30x90 button BMP that's a gradient
image. Saving it as JPG and then zooming 15x shows
an entirely different pattern of pixel colors.

jpeg was designed for real world photos, not pixel peeping 30x90 pixel
buttons with a gradient, and you probably didn't choose the highest
quality either.




An interesting aside to this: IBM just bought
Red Hat. I think it was something like $15B.

try again. it was $34b.
