The PNG Guide is an eBook based on Greg Roelofs' book, originally published by O'Reilly.


In addition to the following three viewers, Al Evans's BePNG and Jeremy Moskovich's BeShow were once available. But incompatibilities in the development versions of BeOS took their toll, and the two viewers were never updated to work with BeOS releases more recent than DR8 or DR9; they have since been moved to the ``obsolete'' area of Be's FTP site. BePNG was unique in having native support for PNG; all of the others use the datatypes facility developed by Jon Watte and later incorporated into the operating system as the BeOS translation kit. PNG support is provided via Simon Clarke's BPNGHandler:

It appeared in October 1998 that PNGHandler might have been renamed to PNGTranslator as of version 1.20 (see also the discussion in Chapter 16, "Other Libraries and Concluding Remarks"), but as of February 1999, the web page still referred to the original name.


Version 3.1.0, Edmund Vermeulen.

Version 1.2 beta 5, Philippe Thomas.

Version 0.90, Frank Fejes. Development apparently ended in February 1997; the app was never updated to work with BeOS versions more recent than DR8.
