NAME

       Bio::Graphics::Glyph::anchored_arrow - The "anchored_arrow" glyph

SYNOPSIS

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

DESCRIPTION

       This glyph draws an arrowhead which is anchored at one or both ends (has a vertical base)
       or has one or more arrowheads.  The arrowheads indicate that the feature does not end at
       the edge of the picture, but continues.  For example:

           |-----------------------------|          both ends in picture
        <----------------------|                    left end off picture
                |---------------------------->      right end off picture
        <------------------------------------>      both ends off picture

       You can also set the glyph so that the end is just truncated at the end of the picture.

   OPTIONS
       The following options are standard among all Glyphs.  See Bio::Graphics::Glyph for a full
       explanation.

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

         -fgcolor      Foreground color               black

         -outlinecolor Synonym for -fgcolor

         -bgcolor      Background color               turquoise

         -fillcolor    Synonym for -bgcolor

         -linewidth    Line width                     1

         -height       Height of glyph                10

         -font         Glyph font                     gdSmallFont

         -connector    Connector type                 0 (false)

         -connector_color
                       Connector color                black

         -label        Whether to draw a label        0 (false)

         -description  Whether to draw a description  0 (false)

         -hilite       Highlight color                undef (no color)

       In addition to the standard options, this glyph recognizes the following:

         Option         Description                Default

         -tick          draw a scale               0 (false)

         -relative_coords
                        use relative coordinates   0 (false)
                        for scale

         -relative_coords_offset
                        set the relative offset    1
                        for scale

         -no_arrows     don't draw an arrow when   0 (false)
                        glyph is partly offscreen

       The argument for -tick is an integer between 0 and 2 and has the same interpretation as
       the -tick option in Bio::Graphics::Glyph::arrow.

       If -rel_coords is set to a true value, then the scale drawn on the glyph will be in
       relative (1-based) coordinates relative to the beginning of the glyph.
