NAME

GD::Tab::Guitar - Guitar tab image generator.

SYNOPSIS

 use GD::Tab::Guitar;
 my $gtr = GD::Tab::Guitar->new;
  
 # print png image
 print $gtr->chord('D#sus4')->png;
 
 # get GD::Image instance
 my $im = $gtr->chord('C');
 print $im->png;
 
 # other tab generate
 $gtr->generate('G7',[1,0,0,0,2,3])->png;
 
 # above fret style (1st string to 6th string) is unfamiliar to most guitarists.
 # you can also specify the reversed and familiar style like this:
 $gtr->generate('G7', '320001')->png;
 
 # if you want to specify some mute strings, put "x" character.
 $gtr->generate('D7', 'x00212')->png;

 # set color
 $gtr->color(255, 0, 0);
 
 # set background-color and no interlace
 $gtr->bgcolor(200, 200, 200);
 $gtr->interlaced(0);
 
 # all tabs image save to file.
 use IO::File;
 for my $chord (@{$gtr->all_chords}) {
     (my $filename = $chord) =~ s/M/Maj/; # for case-insensitive filesystem
     my $file = IO::File->new("images/$filename.png", 'w');
     $file->print($gtr->chord($chord)->png);
 }

DESCRIPTION

GD::Tab::Guitar generates guitar tab scores. This module is inspired by GD::Tab::Ukulele, and it's almost its copy.
