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


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


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


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                black

  -label        Whether to draw a label        0 (false)

  -description  Whether to draw a description  0 (false)

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 -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.
