Hello, I was asked to add a few words of WARNING: first of all all the material in this directory are just released and not extensively tested. If there would seem to be something wrong, trust the file format specification, not the implementation: png10htm.zip Portable Network Graphics (PNG) specs - 10th draft (HMTL) png10ps.zip Portable Network Graphics (PNG) specs - 10th draft (PostScript) png10txt.zip Portable Network Graphics (PNG) specs - 10th draft (ascii) There is a possibility that the included sample pics are not very carefully validated. If they turn out not to agree with the spec, the spec is right, the samples are wrong. Everything in this directory are extremely early development code. Please contact directly the official ftp-site to get the most recent versions. We try to keep up with their updates, but don't count on it! ftp://ftp.uu.net/graphics/png/ ie. ftp ftp.uu.net Use FTP program to connect ftp.uu.net user: anonymous This is "anonymous" ftp connection password: joe@own.machine.net Give your own email address as password cd graphics/png Change into right directory dir See what there is ... bye Exit For more info about PNG file format, please email to: png-info@uunet.uu.net --jouni (I have nothing to do with PNG development)
