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.
