=head1 DESCRIPTION

Svg2AnyFormat is a serializer which can transform SVG to many different
output formats(e.g. png, jpg, ... ). At the moment it uses Image::Magick or LibRSVG as conversion libraries
which do not support the whole set of svg features. In one case the conversion
could work in another not. You have to give it a try. Please note because 
Svg2AnyFormat to any format is a searializer it HAS TO BE LAST in the transformer 
chain!!!!

Please note when referencing external material (e.g. Images) you'll have to use an absolute path

=head2 Image::Magick

If no SVGOutputSerializer is set Image::Magick is used as default. The reason is simply
because of backward compatility. You could also set Image::Magick explicitly with

=head3 Example:

  PerlSetVar SVGOutputSerializer ImageMagick

lib/Apache/AxKit/Language/Svg2AnyFormat.pm  view on Meta::CPAN

=head3 Example:

  PerlSetVar SVGOutputSerializer LibRSVG

=head3 Advantages

=over

=item 

supports more of SVG-spec than Image::Magick

=item

not that big

=back

=head3 Disadvantages:

=over

=item 

* Perl-Module highly experimental

=item

only PNG supported as output format. This is solved by using
Image::Magick in a second transformation step (LOW Performance!!!).
