NAME
Image::TextMode::Reader::ANSI::XS - Fast ANSI image parsing
SYNOPSIS
# The XS reader will automatically be used instead of the pure-perl version
my $ansi = Image::TextMode::Format::ANSI->new
$ansi->read( shift );
DESCRIPTION
To parse an ANSI file, we use a simple state machine and examine each
character individually. This proves to be a little on the slow side in
pure-perl form.
This module endeavors to re-implement the parsing in XS/C. The results
show a major speed increase; about 25 times faster.
INSTALLATION
perl Makefile.PL
make
make test
make install
METHODS
_read( $image, $fh, \%options )
This is an XS-based version of Image::TextMode::Reader::ANSI's method of
the same name.
