2 * The Python Imaging Library.
3 *
4 * standard encoder interfaces for the Imaging library
5 *
6 * History:
7 * 1996-04-19 fl Based on decoders.c
8 * 1996-05-12 fl Compile cleanly as C++
9 * 1996-12-30 fl Plugged potential memory leak for tiled images
10 * 1997-01-03 fl Added GIF encoder
11 * 1997-01-05 fl Plugged encoder buffer leaks
12 * 1997-01-11 fl Added encode_to_file method
13 * 1998-03-09 fl Added mode/rawmode argument to encoders
14 * 1998-07-09 fl Added interlace argument to GIF encoder
15 * 1999-02-07 fl Added PCX encoder
