NAME

       Ace::Graphics::Glyph::transcript - The "gene" glyph

SYNOPSIS

         See L<Ace::Graphics::Panel> and L<Ace::Graphics::Glyph>.

DESCRIPTION

       This glyph draws a series of filled rectangles connected by up-angled connectors or
       "hats".  The rectangles indicate exons; the hats are introns.  The direction of
       transcription is indicated by a small arrow at the end of the glyph, rightward for the +
       strand.

       The feature must respond to the exons() and optionally introns() methods, or it will
       default to the generic display.  Implied introns (not returned by the introns() method)
       are drawn in a contrasting color to explicit introns.

   OPTIONS
       In addition to the common options, the following glyph-specific option is recognized:

         Option                Description                    Default
         ------                -----------                    -------

         -implied_intron_color The color to use for gaps      gray
                               not returned by the introns()
                               method.

         -draw_arrow           Whether to draw arrowhead      true
                               indicating direction of
                               transcription.
