Apologies - didn't know. Here it is:

convert produces correct results for every format checked except tiff:

convert 5PsYMkaHJ3.pnm 5PsYMkaHJ3.tif

imagemagick displays the result correctly:

display 5PsYMkaHJ3.tif

but kwickshow, GIMP, etc all display an inverted image.

$ convert -version
Version: ImageMagick 6.3.3 03/19/07 Q16 http://www.imagemagick.org

on RHEL 4.

$ convert -version
Version: ImageMagick 6.2.4 07/09/07 Q16 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2005 ImageMagick Studio LLC

on Ubuntu Feisty seems to produce correct results.

Please CC me on replies.
