       Ace::Graphics::GlyphFactory - Create Ace::Graphics::Glyphs


         use Ace::Graphics::GlyphFactory;

         my $factory = Ace::Graphics::GlyphFactory($glyph_name,@options);


       The Ace::Graphics::GlyphFactory class is used internally by Ace::Graphics::Track and
       Ace::Graphics::Glyph to hold the options pertaining to a set of related glyphs and
       creating them on demand.  This class is not ordinarily useful to the end-developer.


       This section describes the class and object methods for Ace::Graphics::GlyphFactory.

       There is only one constructor, the new() method.  It is ordinarily called by
       Ace::Graphics::Track, in the make_factory() subroutine.

       $factory = Ace::Graphics::GlyphFactory->new($glyph_name,@options)
           The new() method creates a new factory object.  The object will create glyphs of type
           $glyph_name, and using the options specified in @options.  Generic options are
           described in Ace::Graphics::Panel, and specific options are described in each of the
           Ace::Graphics::Glyph::* manual pages.  =back

       Once a track is created, the following methods can be invoked:

       $glyph = $factory->glyph($feature)
           Given a sequence feature, creates an Ace::Graphics::Glyph object to display it.  The
           various attributes of the glyph are set from the options provided at factory creation

       $option = $factory->option($option_name [,$new_option])
           Given an option name, returns its value.  If a second argument is provided, sets the
           option to the new value and returns its previous one.

       $index = $factory->fgcolor
           Returns the desired foreground color for the glyphs in the form of an GD::Image color
           index.  This may be the one of the special colors gdBrushed and gdStyled.  This is
           only useful while the enclosing Ace::Graphics::Panel object is rendering the object.
           In other contexts it returns undef.

       $scale = $factory->scale([$scale])
           Get or set the scale, in pixels/bp, for the glyph.  This is ordinarily set by the
           Ace::Graphics::Track object just prior to rendering, and called by each glyphs'
           map_pt() method when performing the rendering.

       $color = $factory->bgcolor([$color])
           Get or set the background color for the glyphs.

       $color = $factory->fillcolor([$color])
           Get or set the fill color for the glyphs.

       $font = $factory->font([$font])
           Get or set the font to use for rendering the glyph.

       $color = $factory->fontcolor
           Get the color for the font (to set it, use fgcolor()).  This is subtly different from
           fgcolor() itself, because it will never return a styled color, such as gdBrushed.

       $panel = $factory->panel([$panel])
           Get or set the panel that contains the GD::Image object used by this factory.

       $index = $factory->translate($color)
       @rgb = $factory->rgb($index)
           These are convenience procedures that are passed through to the enclosing Panel object
           and have the same effect as the like-named methods in that class.  See


       Please report them.
