Pee En Gee – See Ya Real Soon!

Pee En Gee – See Ya Real Soon! — Delightfully, I was wrong about current browser support in the NetBITS-007 article on graphic file formats for the Web. The recently released Netscape Navigator 4.0.4 update – which includes a variety of bug fixes – slipped in Macintosh and Windows PNG (Portable Network Graphics) file support. Microsoft is lagging in supporting PNG in its current preview of the Macintosh release, but the final release of Macintosh Internet Explorer 4.0 is due late this year, and will probably be in parity with the Windows release, which does have PNG capability.

Both browsers support 2D interlacing – where an image gradually comes in by sending a few pixels over a grid, rather than sending a full line of pixels at a time – and there’s a great page where you can both see if your browser displays PNGs and view a great illustrated example of this capability.
