# Bio::Graphics::Glyph::anchored\_arrow(3pm)

The "anchored\_arrow" glyph

## 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.
