# Ace::Graphics::Glyph::segments(3pm)

The "discontinuous segments" glyph

## NAME

Ace::Graphics::Glyph::segments - The "discontinuous segments" glyph

## SYNOPSIS

```
  See L<Ace::Graphics::Panel> and L<Ace::Graphics::Glyph>.
```

## DESCRIPTION

This glyph draws a sequence feature that consists of multiple discontinuous segments, such as the exons on a transcript or a gapped alignment.  The representation is a series of filled rectangles connected by line segments.

The features passed to it must either respond to the Bio::SequenceFeatureI-style **subSeqFeatures()** method, or the AcePerl/Das-style **segments()** or **merged\_segments()** methods.

### OPTIONS

In addition to the common options, this glyph recognizes the b\<-stranded\> argument.  If b\<-stranded\> is true and the feature is an alignment (has the **target()** method) then the glyph will draw little arrows in the segment boxes to indicate the direction of the alignment.

## BUGS

Please report them.
