seq2gif

Description

This software converts a sequences record file generated by ttyrec into a gif animation directly using portable built-in terminal emulation engine originated from yaft. yaft provides rare terminal emulation features such as SIXEL/DRCS.

Demo

This demo plays sl and records it with ttyrec, and converts that record into a GIF animation using seq2gif, and converts that GIF into a SIXEL animation and plays it with img2sixel. Furthermore, generates the log record of above experience using ttyrec, and converts that log into the following GIF animation.

Build and Install

  $ ./configure
  $ make
  # make install
