Description of problem:

ImageMagick does not return the correct values for image dimensions.  More
information follows:

Redhat 7.3
ImageMagick-perl-, ImageMagick-,
ImageMagick-devel-, ImageMagick-c++-devel-,

First with ImageMagick:

use Image::Magick;
$imageName = "/tmp/001.jpg";

my $preview = new Image::Magick;
($width, $height, $size, $format) = $preview->Ping($imageName);
print "width: $width\nheight: $height\n";
width: 191
height: 154

Now with Image::Info:
use Image::Info qw(image_info dim);
$imageName = "/tmp/001.jpg";

my $info = image_info($imageName);
my($w, $h) = dim($info);
print "width: $w\nheight: $h\n";
width: 1523
height: 1228

Image::Info has the correct values.  Seems ImageMagick's Ping routine has a
problem.  When I installed the source (from ImageMagick's wesite), everything
worked fine.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install Red Hat's ImageMagick RPMs
2. Install Image::Info 1.11 from CPAN
3. Run the above perl code on an image of known dimensions

Actual Results:  ImageMagick always came back with odd (very small) numbers
compared to other routines that collects image dimensions.

Expected Results:  Expected results?  Um, the correct information would be nice.
