=head1 NAME
Circos::Image - utility routines for bitmap images and drawing in Circos
=head1 SYNOPSIS
This module is not meant to be used directly.
=head1 DESCRIPTION
Circos is an application for the generation of publication-quality,
circularly composited renditions of genomic data and related
annotations.
Circos is particularly suited for visualizing alignments, conservation
and intra and inter-chromosomal relationships. However, Circos can be
used to plot any kind of 2D data in a circular layout - its use is not
limited to genomics. Circos' use of lines to relate position pairs
(ribbons add a thickness parameter to each end) is effective to
display relationships between objects or positions on one or more
scales.
All documentation is in the form of tutorials at L<http://www.circos.ca>.
