=head1 NAME
Bio::Graphics::Glyph::redgreen_segments - The "redgreen_segments" glyph
=head1 SYNOPSIS
See L<Bio::Graphics::Panel> and L<Bio::Graphics::Glyph>.
=head1 DESCRIPTION
This glyph is similar to the graded_segments glyph except that it
generates a green-E<gt>red gradient suitable for use with microarray data.
A feature score of 0 is full green; a feature score of 1.0 is full
red; intermediate scores are shades of yellow.
=head2 OPTIONS
The following options are standard among all Glyphs. See
L<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)
