Greg isn't what you'd call a prolific author, but he has written
a few things on occasion. Here are some of them:
PNG Lossless Image Compression - Lossless Compression Handbook, Academic Press (now part of
Elsevier Science), December 2002
A more academically oriented work, edited by Khalid
Sayood, covering lossless compression techniques from ``generic data''
to images to audio. Greg's chapter (19) covers PNG image compression, but
in considerably more technical detail than the corresponding chapter in his
own book (below).
Interview with Greg Roelof[s] - Designing CSS Web Pages, New Riders, September 2002
designer-oriented book is primarily focused on Cascading Style Sheets (CSS),
of course, but images are almost always involved, too. Greg was interviewed
via e-mail for Chapter 7, Utilizing PNG and SVG with CSS, and
much of the interview is included. So are screen shots of several pages
from the Portable Network Graphics
(PNG) Home Site. (Alas, Greg's last name is misspelled
throughout the chapter, but such are the slings and arrows
of . . . something or other.)
Mini-HOWTO - Linux Documentation Project, 26 January
2002, 20 September 2002
Greg wasn't the original author of this HOWTO, but after it had lain dormant
for more than four years, he performed a one-time update and then handed it
off to a new maintainer . . . or so he thought. Eight months
later nothing further had happened, so he submitted one more update and
left it at that. Additions included information on the Linux 2.4 kernel
series, DHCP booting, developing for embedded systems, and setting up and
troubleshooting the NFS server. In all, the update added more than 50% to
the size of the document. (OK, Greg can be a tad verbose sometimes.)
MNG, JNG and Mozilla M17 - Slashdot, 26 June 2000
Another status update on PNG, emphasizing the features most useful for the
Web and the browsers that best support them. As with the previous article, a
corrected version is available from the PNG site.
Viewer - Web Review, 10 December 1999
A mini-review of the premier Unix image viewer, XV; part of a special
``Cheapskate Edition'' of Web Review that covered 14 low-cost (less than
$100) utilities, HTML
tools, and graphics
and multimedia tools.
PNG Gaining Acceptance - Web Review, 13 August
An update on the 1997 article; also part of a special feature issue covering
three ``new'' image formats for the Web: PNG, SVG and JPEG 2000.
Definitive Guide - O'Reilly and Associates, June 1999
A fine tome covering all aspects of the PNG image format, from its history
to application support to PNG
image-creation to writing programs with PNG support. There's even
to three real, live, PNG demo applications (two viewers and a converter), and
Greg wrote up some notes and a timeline on the whole process.
Story of PNG - Slashdot, 18 March 1999
A status update on PNG, with particular emphasis on clearing up
misinformation and generally attempting to provide a fair comparison of
PNG and other image formats. A ``printer-friendly'' and slightly updated/corrected
version of the article is available from the PNG site.
Future of Linux - Linux Journal, October 1998
An informal report on the panel discussion of the same name, which took
place in Silicon Valley in July 1998. An updated version of the article is
also available locally.
PNG's Not GIF! - Web Review, 9 May 1997
A general overview of PNG's features and capabilities, written primarily for
History of the
Portable Network Graphics (PNG) format - Linux Gazette,
January 1997, and Linux Journal, April 1997
A quick overview of the events leading up to the creation of the PNG image format and of its progress
over the next couple of years. An updated version of the
article is also available at the PNG home site. (The updates are in the
form of Author's Notes at the end.)
Command: unzip - Linux Journal, January 1997
A short how-to covering the most basic UnZip tasks: listing,
testing and extracting a Zip archive.
Radial Motions in Spiral Galaxies
- University of Chicago / UMI, December 1995
which considered the possibility that some ``warped'' spiral galaxies might
actually be flat but oscillating radially. (Answer: probably not.)
