NAME

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

SYNOPSIS

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

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

         Option         Description                Default

         -tick          draw a scale               0
         -rel_coords    use relative coordinates   false
                        for scale

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

       If b<-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.
