What you are going does not make sense!

First read in the image, then chop it correctly!

Ah, OK. I'm used to unix switches being put before
the command arguments. In fact, convert doesn't seem to
mind at all if I put the chop switch before the
filename argument (when I give the chop switch the correct
width format). Actually, all of the examples on the command-line
docmentation page are in the format:

convert -transform -switches in.file out.file

so I don't think you're correct.

   convert duc00014.jpg -chop 50x0+0+0 out.jpg

[EMAIL PROTECTED] test]$ convert duc00014.jpg -chop 50 out.jpg
convert: magick/cache.c:2383: GetNexus: Assertion `cache_info->number_views != 0UL' failed.
Aborted

My point, I suppose, is that the docs say:

from http://www.imagemagick.com/www/command-line-options.html#chop

-chop width{%}

...and that chop doesn't seem to work using only a width argument,
you need to give it widthx0. This I think is an error in the
documentation. Agreed?
