Image::TextMode::Reader::ANSI::XS - Fast ANSI image parsing
# The XS reader will automatically be used instead of the pure-perl version my $ansi = Image::TextMode::Format::ANSI->new $ansi->read( shift );
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.
