Compare the following 3 commands. The results show that only the first works correctly. The other two show that it does not matter if the png or jpg is used for either the intermediate or final result. Both are wrong.

convert -size 256x256 gradient: -rotate 90 -solarize 50% -level 0x50% grad_solarize50a.png


convert -size 256x256 gradient: -rotate 90 grad.png
convert grad.png -solarize 50% -level 0x50% grad_solarize50b.png


convert -size 256x256 gradient: -rotate 90 grad.jpg
convert grad.jpg -solarize 50% -level 0x50% grad_solarize50c.jpg

We can reproduce the problem you posted and have a patch in ImageMagick 6.8.7-9 Beta available by sometime tomorrow. Thanks.
