In moving from 6.4.5-7 to 6.4.5-8, we've noticed a change in the behavior
of the convert command. I can't find anything in the mailing list or
ChangeLogs that would lead me to believe that this was intentional.
Start with a 640x480 png image, then run:
convert foo.png -thumbnail 150x150 foo.gif
With the 6.4.5-7 version of convert, running identify on foo.gif would yield:
foo.gif GIF 150x113 150x113+0+0 8-bit PseudoClass 64c 3.89kb
but with 6.4.5-8, the result is:
foo.gif GIF 150x113 640x480+0+0 8-bit PseudoClass 64c 3.21kb
^^^^^^^
Since the "screen descriptor" is still set to 640x480, the web
browser is treating it as a 640x480 image, though only the 150x113
pixels in the corner are actually used.
