EvaluateImages()
Posted: 2018-02-05T13:01:19-07:00
I think I'm doing what I'm told in the doc, but I'm getting an error. Doc says,
Instead it dies without the warning with the following output:

But I get an error in the following script:The EvaluateImages() method applies an arithmetic, logical or relational expression to a set of images. For example,
$p = $image->EvaluateImages('mean');
averages all the images associated with object $image.
Code: Select all
use Image::Magick;
$images = new Image::Magick;
$notok = $images->Read("rose:", "rose:");
die "on roses: $notok" if $notok;
printf("\$images contains %d rosey images\n", scalar(@$images));
$image = $images->EvaluateImages('mean');
print "I never get here and I don't even get a warning.\n";
$images->Write("rosey.png");
$image->Write("rosey-mean.png");Is it me? I'm using ImageMagick 7.0.7-15 Q16 x86_64 2018-01-17 on Centos 6.9 with perl v5.10.1.$images contains 2 rosey images
