GraphicsMagick no longer produces such annoying warnings.

GraphicsMagick was quieted by commenting out source code so there is 
no exception. :-)

There is still logging of warnings though, but this only appears if 
logging is enabled.

You can build an exception-handling framework to catch the warnings 
and ignore them before they do any harm.  See the documentation at 
"http://www.graphicsmagick.org/Magick++/Exception.html".  The sample 
code there even mentions TIFF warnings.

I am not sure how you would pass a -quiet option into ImageMagick. 
Soon it will be 10 years since the split.

Feel free to convert to GraphicsMagick.  You will be welcomed.
