i have imagemagick 6.3.7 installed on a debian distro. timelapseguest@timelapse:~$ convert /scratch/tmp*.jpg -evaluate-sequence mean foo.jpg convert: unrecognized option `-evaluate-sequence'. and now i just discovered that all the tmp*.jpg files i was trying to average were bogus files and i feel ...

timelapseguest@timelapse:~$ convert /scratch/tmp*.jpg -average foo.png convert: missing an image filename `foo.png'. i've used this line on other machines and not gotten an error. this is really confusing me... tried it with a bunch of different convert stuff and always getting this same error ...

composite -compose Dst_Out -gravity center stripesHORZ.gif image2.jpg temp2.png

so not a typo problem as far as i know...

i made some stripes with this command: convert -size 1x100 pattern:gray50 -scale 640x480\! stripesHORZ.gif composite -compose Dst_In -gravity center stripesHORZ.gif image2.jpg temp1.png composite -compose Dst_Out -gravity center stripesHORZ.gif image2.jpg temp2.png convert temp1.png temp2.png ...

thanks!
