Bio::Graphics::RendererI(3) User Contributed Perl Documentation Bio::Graphics::RendererI(3)

Bio::Graphics::RendererI - A renderer for the Bio::Graphics class that renders Bio::SeqFeature::CollectionI objects onto Bio::Graphics::Panels using configuration information provided by a Bio::Graphics::ConfiguratorI.

 # Get a renderer somehow, called $renderer
 # create a new panel and render contents a feature collection onto it
 my $config = new ConfigIO( $config_file )->getConfig();
 my $features = $data_provider->getCollection();
 my ( $tracks_rendered, $panel ) = $renderer->render( $features, $prefs );

Renderer of Bio::SeqFeature::CollectionIs (collections of features) onto a Bio::Graphics::Panel using a Bio::Graphics::ConfiguratorI for general and track-specific rendering options.
