I cannot seem to open your links or they take very long time. But please provide your IM version and platform and the exact command you used.

Your command works just fine for me on IM 6.8.9.0 Q16 Mac OSX.

What is your IM version and platform? There may be a bug in your version.

The other thing to try is add a little fuzz factor to it.

Code: Select all

  convert balloon.gif  -fuzz X% -fill white -opaque blue   balloon_white.gif
try 1% and if that does not work, then try larger amounts. If it still does not work, the you may need to upgrade IM.
