[magick-users] cropping animated gifs

[Lex Thoonen]

Hi Magick-users,

I'using ImageMagick in a cgi script, to resize & crop uploaded mages
to the desired format for the particular site.

All is well, for jpg.

But when I try a (animated) gif, it goes wrong. It crops away the parts that need
to be cut away, but leaves them in the canvas so to say. I mean, the
sizes of the images haven't changed.

You can see what i mean here:
http://www.allesoversterrenkunde.nl/test/upload.html

Here's what I do:

      $cropcommand = $MaxFullimgX ."x" . $MaxFullimgY ."+" . $cropwidth ."+" . $cropheight ;
      $image->Crop( geometry=>$cropcommand , gravity=>'Center' ); # crop the image


Now, at this page: http://tinyurl.com/cfkopm

an answer is to a similar question is:

To do it properly use...
    convert jumping_egg.gif -crop 146x167+20+25! cropped.gif


Is there someone who knows if/how I can convert this to work in my cgi
script? (And if that's the way forward?)

Thanks,
