6            
7             my $canvas = Term::Graille->new(
8             width => 72, # pixel width
9             height => 64, # pixel height
10             top=>3, # row position in terminal (optional,defaults to 1)

15             =head1 DESCRIPTION
16              
17             Inspired by Drawille by asciimoo, which has many variants (including
18             a perl variant Term::Drawille by RHOELZ), this is a clone with a few
19             extras. The goal is to achieve performance and features. with built-in
20             turtle-like graphics, line and curve drawing (Algorithm::Line::Bresenham),
21             scrolling, border setting, and more in development.
