Unix
- Cameleo
-
Version 3.0 beta, Caldera Graphics. Conversion capabilities; claims full
16-bit-per-sample support and strongly implies full gamma and color correction,
including ICC profiles.

- Electric Eyes
-
Red Hat Advanced Development Labs. Electric Eyes is a new,
Linux/GNOME-based image viewer by The Rasterman (who's perhaps better
known for his spectacularly fancy Enlightenment desktop). It is also
one of the prototype applications for
Imlib, an X-based imaging toolkit described in Chapter 16, "Other Libraries and Concluding Remarks".

- GRAV
-
Version 3.5, Michael Knigge. Broken support for 24-bit images.
GRAV is a non-X-based image viewer for Linux, similar to Zgv, later in this list; it
uses svgalib to display on a Linux console. It has not been updated
since January 1996 and apparently is no longer under development.

- Image Alchemy
-
Version 1.11, Handmade Software. Conversion
capabilities (in fact, primarily a command-line conversion tool); claims full
alpha support, gamma support, and support for ICC profiles via ColorSync. Note
that only the versions for DOS and Macintosh and the commercial versions for
Sun, SGI, and HP workstations include viewing capability.

- ImageMagick display
-
Version 4.2.0, John Cristy. Conversion
capabilities (mostly via accompanying convert utility); full gamma
support; partial MNG support. There is also a 32-bit Windows port, but it
requires a third-party X server to run.

- Photon Picture Viewer/pv
-
QNX Software Systems. No gamma support;
QNX only. The Photon Picture Viewer is part of the Photon microGUI and can be
downloaded as part of QNX's 1.44 MB ``Internet Appliance'' demo diskette.

- PingPong
-
Version 1.28, Willem van Schaik. Conversion capabilities (PNG to TIFF
only, apparently, with preservation of alpha/transparency); NeXTStep
and OpenStep only.

- Quick View Plus
-
Version 4.5, Inso. There is also a version 5.0 for Windows, sold by
Jasc Software; see the listing in the 32-bit Windows section for at
least part of the strange story.

- ToyViewer
-
Version 3.02, Takeshi Ogihara. Conversion capabilities;
transparency support; support for writing text comments; NeXTstep and OpenStep
only. The latest NeXTStep version is 2.6a.

- Viewpng
-
Version of May 9, 1997, Glenn Randers-Pehrson. Full alpha and
gamma support; partial (out-of-date) MNG support; SGI IRIX only. Viewpng
requires the separate pnggzip utility (included) for its compression and
decompression.

- xli
-
Version 1.16, Graeme Gill. Like XV, the next entry, xli (a modified
version of xloadimage) has not been updated since 1994, before PNG was
born. But it is available as C source code from ftp.x.org and
elsewhere, and a PNG patch by Smarasderagd has been available for years, so
compiling a PNG-capable version is straightforward.

- XV
-
Version 3.10a, John Bradley. Conversion capabilities, including
interlacing support but without the ability to write transparent PNGs; full
gamma support; preserves text information. XV is widely considered to be the
preeminent image viewer for the X Window System.[22]
The only major drawback is that it was last released in December 1994,
five days before the CompuServe/Unisys GIF announcement that began the
PNG saga and therefore does not include PNG support in the default
distribution. Fortunately, it is available as C source code, and the
home page includes not only the PNG patch but also several others, so
it can be recompiled and tweaked at will. An upcoming patch will
allow an image-background color to be set, similar to the
-bgcolor option in the demo viewers in Chapter 13, "Reading PNG Images" and Chapter 14, "Reading PNG Images Progressively".

- Zgv
-
Version 3.0, Russell Marks. Zgv is a non-X-based image viewer for
Linux, similar to GRAV, earlier in this list; it uses svgalib to
display on a Linux console.
