Bio::Graphics::Glyph::Factory - Factory for Bio::Graphics::Glyph objects

       The rest of the documentation details each of the object methods. Internal methods are usually preceded
       with an "_" (underscore).

   new
         Title   : new
         Usage   : $f = Bio::Graphics::Glyph::Factory->new(
                            -stylesheet => $stylesheet,
                            -glyph_map  => $glyph_map,
                            -options    => $options);
         Function : create a new Bio::Graphics::Glyph::Factory object
         Returns  : the new object
         Args     : $stylesheet is a Bio::Das::Stylesheet object that can
                        convert Bio::Das feature objects into glyph names and
                        associated options.
                    $glyph_map is a hash that maps primary tags to glyph names.
                    $options is a hash that maps option names to their values.
         Status   : Internal to Bio::Graphics

   clone
         Title    : clone
         Usage    : $f2 = $f->clone
         Function : Deep copy of a factory object
         Returns  : a deep copy of the factory object
         Args     : None
         Status   : Internal to Bio::Graphics

   stylesheet
         Title    : stylesheet
         Usage    : $stylesheet = $f->stylesheet
         Function : accessor for stylesheet
         Returns  : a Bio::Das::Stylesheet object
         Args     : None
         Status   : Internal to Bio::Graphics

   glyph_map
         Title    : glyph_map
         Usage    : $map = $f->glyph_map
         Function : accessor for the glyph map
         Returns  : a hash mapping primary tags to glyphs
         Args     : None
         Status   : Internal to Bio::Graphics

   option_map
         Title    : option_map
         Usage    : $map = $f->option_map
         Function : accessor for the option map
         Returns  : a hash mapping option names to values
         Args     : None
         Status   : Internal to Bio::Graphics

   global_opts
         Title    : global_opts
         Usage    : $map = $f->global_opts
         Function : accessor for global options
         Returns  : a hash mapping option names to values
         Args     : None
         Status   : Internal to Bio::Graphics

       This returns a set of defaults for option values.

   panel
         Title    : panel
         Usage    : $panel = $f->panel
         Function : accessor for Bio::Graphics::Panel
         Returns  : a Bio::Graphics::Panel
         Args     : None
         Status   : Internal to Bio::Graphics

       This returns the panel with which the factory is associated.

   scale
         Title    : scale
         Usage    : $scale = $f->scale
         Function : accessor for the scale
         Returns  : a floating point number
         Args     : None
         Status   : Internal to Bio::Graphics

       This returns the scale, in pixels/bp for glyphs constructed by this factory.

   font
         Title    : font
         Usage    : $font = $f->font
         Function : accessor for the font
         Returns  : a font name
         Args     : None
         Status   : Internal to Bio::Graphics

       This returns a GD font name.

   map_pt
         Title    : map_pt
         Usage    : @pixel_positions = $f->map_pt(@bp_positions)
         Function : map bp positions to pixel positions
         Returns  : a list of pixel positions
         Args     : a list of bp positions
         Status   : Internal to Bio::Graphics

       The real work is done by the panel, but factory subclasses can override if desired.

   map_no_trunc
         Title    : map_no_trunc
         Usage    : @pixel_positions = $f->map_no_trunc(@bp_positions)
         Function : map bp positions to pixel positions
         Returns  : a list of pixel positions
         Args     : a list of bp positions
         Status   : Internal to Bio::Graphics

       Same as map_pt(), but it will NOT clip pixel positions to be within the drawing frame.

   translate_color
         Title    : translate_color
         Usage    : $index = $f->translate_color($color_name)
         Function : translate symbolic color names into GD indexes
         Returns  : an integer
         Args     : a color name in format "green" or "#00FF00"
         Status   : Internal to Bio::Graphics

       The real work is done by the panel, but factory subclasses can override if desired.

   transparent_color
         Title    : transparent_color
         Usage    : $index = $f->transparent_color($opacity,$color_name)
         Function : translate symbolic color names into GD indexes, with
                       an opacity value taken into account
         Returns  : an integer
         Args     : an opacity value from 0-1.0, plus a color name in format "green" or "#00FF00"
         Status   : Internal to Bio::Graphics

       The real work is done by the panel, but factory subclasses can override if desired.

   make_glyph
         Title    : make_glyph
         Usage    : @glyphs = $f->glyph($level,[$type,]$feature1,$feature2...)
         Function : transform features into glyphs.
         Returns  : a list of Bio::Graphics::Glyph objects
         Args     : a feature "level", followed by a list of FeatureI objects.
         Status   : Internal to Bio::Graphics

       The level is used to track the level of nesting of features that have subfeatures. The option $type
       argument can be used to force the glyph type

   feature_to_glyph
         Title    : feature_to_glyph
         Usage    : $glyph_name = $f->feature_to_glyph($feature)
         Function : choose the glyph name given a feature
         Returns  : a glyph name
         Args     : a Bio::Seq::FeatureI object
         Status   : Internal to Bio::Graphics

   set_option
         Title    : set_option
         Usage    : $f->set_option($option_name=>$option_value)
         Function : set or change an option
         Returns  : nothing
         Args     : a name/value pair
         Status   : Internal to Bio::Graphics

   options
         Title    : options
         Usage    : @option_names = $f->options
         Function : return all configured option names
         Returns  : a list of option names
         Args     : none
         Status   : Internal to Bio::Graphics

       This class is used internally by Bio::Graphics to generate new Glyph objects by combining a list of
       features with the user's desired configuration.  It is intended to be used internally by Bio::Graphics.
