Hello, Quoting sedachv@cpsc.ucalgary.ca:

Which version of zlib does file-png use? Neither the pure CL nor Marc Battyani's from CL-PNG have the same interface. It would also be good to include it in the CVS.

IMAGO uses the ZLIB project also hosted on common-lisp.net: http://common-lisp.net/project/zlib/ This will be in a README file in the project, as soon as I have time to write it. I prefer having the ZLIB code in a separate project, so that bug fixes do not have to be done twice, and echoing changes in the interface to IMAGO would be very quick (if any are done). -- Matthieu Villeneuve
