This is the README for PingPong.1.21.NI.b.tar.gz [Download] [Browse] [Up]
----------------------------------------------------------------------- This is a very simple PNG (Portable Network Graphics) viewer for NeXTstep. You can open PNG files by double-clicking on them and you can save them as TIFF files. PNG-files with alpha channel or transparency chunck are displayed on a light-gray background and will be converted to TIFF files with alpha. The info-panel gives a demo of the Adam-7 interlacing method adopted by the PNG standard. To install, uncompress by "gzip -d PingPong-#.##-NI.tar.gz", followed by "tar xvf PingPong-#.##-NI.tar" or use Opener.app. Then copy the PingPong.app to either your ~/Apps or to /LocalApps. After logout and login, you can view a PNG-file by double-clicking on it. This utility uses the libpng software written by Guy Eric Schalnat, the libz compression library from Jean-loup Gailly and Mark Adler and I stole a lot from the .pic viewer written by by Don Yacktman. This program is freeware: you may copy, distribute and use this application as long as no fee is charged beyond standard distribution fees. I always appreciate it of course to hear something from a happy user, so send me your comments. Because I run NeXTstep 3.2 (on a NeXTstation color), I could only compile for M86K and I386. If you need a version for HP or SUN, send me a mail to get the sources.
