The older version may have had a bug in -virtual-pixel or it was not implemented in -distort perspective. Try other -virtual-pixel settings such as black or white or perhaps first try -background none -virtual-pixel background. See what you get from those.

Hello,
thanks for your answer.
No changes with -virtual-pixel black or -background none -virtual-pixel background ...
You talk of old version but there is a significant difference between 6.6.2 and 6.6.0 ?
Somebody have another idea ?
Best regards,
Sylvain

Imagemaagick is always changing and it has to change at some point; it could have been then. A bug may have been introduced when something else was changed.

ok thanks.
I uninstall imagemagick 6.6.0 (this version was installed automatically with apt-get).
I compile imagemagick ( as explain here :
http://www.imagemagick.org/script/insta ... e.php#unix) in version 6.7.8 and all is right !
Thanks for your help
