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.
