NAME
    Image::Info::SVG - SVG support for Image::Info

SYNOPSIS
     use Image::Info qw(image_info dim);

     my $info = image_info("image.svg");
     if (my $error = $info->{error}) {
         die "Can't parse image info: $error\n";
     }
     my $title = $info->{SVG_Title};

     my($w, $h) = dim($info);

DESCRIPTION
    This modules supplies the standard key names except for BitsPerSample, Compression, Gamma,
    Interlace, LastModificationTime, as well as:

    ImageDescription
        The image description, corresponds to <desc>.

    SVG_Image
        A scalar or reference to an array of scalars containing the URI's of embedded images (JPG or
        PNG) that are embedded in the image.

    SVG_StandAlone
        Whether or not the image is standalone.

    SVG_Title
        The image title, corresponds to <title>

    SVG_Version
        The URI of the DTD the image conforms to.

METHODS
  process_file()
            $info->process_file($source, $options);

    Processes one file and sets the found info fields in the $info object.

FILES
    This module requires either XML::LibXML::Reader or XML::Simple.

COMPATIBILITY
    Previous versions (until Image-Info-1.28) used XML::Simple as the underlying parser. Since
    Image-Info-1.29 the default parser is XML::LibXML::Reader which is much more faster,
    memory-efficient, and does not rely on regular expressions for some aspects of XML parsing. If
    for some reason you need the old parser, you can force it by setting the variable
    @Image::Info::SVG::PREFER_MODULE as early as possible:

        use Image::Info;
        @Image::Info::SVG::PREFER_MODULE = qw(Image::Info::SVG::XMLSimple Image::Info::SVG::XMLLibXMLReader);

    The variable $Image::Info::SVG::USING_MODULE can be queried to see which parser is in use (after
    Image::Info::SVG is required).

    Since 1.38_50 processing of XML external entities (XXE) is not done anymore for security reasons
    in both backends (Image::Info::SVG::XMLLibXMLReader and Image::Info::SVG::XMLSimple).
    Controlling XXE processing behavior in XML::Simple is not really possible (see
    <https://rt.cpan.org/Ticket/Display.html?id=83794>), so as a workaround the underlying SAX
    parser is fixed to XML::SAX::PurePerl which is uncapable of processing external entities — but
    unfortunately it is also a slow parser.
