NAME

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

CONTENTS

SYNOPSIS



 use Image::Info qw(image_info dim);

 my $info = image_info("image.svg");
 if (my $error = $info->{error}) {
     die "Cant 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 <B>Image::Info::SVGB> is required).

SEE ALSO

Image::Info, XML::LibXML::Reader, XML::Simple

Random notes:



  Colors
    # iterate over polygon,rect,circle,ellipse,line,polyline,text for style->stroke: style->fill:?
    #  and iterate over each of these within <g> too?! and recurse?!
    # append <color>s
    # perhaps even deep recursion through <svg>s?
  ColorProfile <color-profile>
