G'day mldvx4,

As I'm not a user of Image::Magick, I left responses to those with more knowledge; however, I see after two days you still have no resolution, so here's some suggestions.

Image::Magick has minimal documentation and points to "PerlMagick Image API for Perl". That appears to be rather dated ("Copyright © 1999") and has Perl code of a similar vintage. It has various issues such as no I/O exception handling and use of a package variable for a filehandle. It looks like your posted code is based on this.

I'd probably write it more like this:

#!/usr/bin/perl

use strict;
use warnings;
use autodie;  # for I/O exception handling

use Image::Magick;

my $svg_filename = '/path/to/some.svg';
my $image = Image::Magick::->new();
open my $fh, '<', $svg_filename;
my $err = $image->Read(file => $fh);

if ($err) {
    print "Error b: $err\n";
    exit 1;
}

close $fh;  # moved after any code related to $fh

print "OK\n";

exit 0;

You said: "I gave it a try and switched from using a file handle to using just a file name ...". I don't know how you implemented that in code; I've used both a filehandle ($fh) and a filename ($svg_filename).

Do note that is untested code: I don't have Image::Magick installed.
