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.
