I tried to use Compare function in Image::Magick module to compare 2
images, but I cannot get it work. I don't know what's the required
image handle. I searched in google, and was unable to find any
examples. Anyone can give some help?
Thanks in advance!

Since you're comparing two images, you need two image objects. You're
invoking the Compare method on one. The image handle it's looking for
is simply the other image object. So you might have something like
$image1 = Image::Magick->new;
$status = $image1->Read($file1);
warn "$statusn" if $status;
$image2 = Image::Magick->new;
$status = $image2->Read($file2);
warn "$statusn" if $status;
$status = $image1->Compare(image => $image2);
warn "$statusn" if $status;
print "mean error per pixel: ", $image1->Get('error'), "n";
I hope this helps,
Tim
