Games::OpenGL::Font::2D module can load/render 2D colored bitmap fonts via OpenGL.

SYNOPSIS

use Games::OpenGL::Font::2D;

my $font = Games::OpenGL::Font::2D->new(
file => font.bmp );

use SDL::App::FPS;

my $app = SDL::App::FPS->new( ... );

# dont forget to change these on resize events!
$font->screen_width( $app->width() );
$font->screen_height( $app->width() );

$font->pre_output(); # setup rendering for font

$font->color( [ 0,1,0] ); # yellow as array ref
$font->color( 1,0,0 ); # or red
$font->alpha( 0.8 ); # nearly opaque

# half-transparent, red
$font->output (100,100, Hello OpenGL!, [ 1,0,0], 0.5 );
# using the $fonts color and alpha
$font->output (100,200, Hello OpenGL! );

$font->transparent( 1 ); # render font background transparent

$font->spacing_y( 16 ); # render vertical (costly rebuild!)
$font->spacing_x( 0 ); # (costly rebuild!)
$font->output (100,200, Hello OpenGL! );

$font->post_output(); # if wanted, you can reset OpenGL
