This is (yet another?) viewer program for picture files. But this one is
special, for a number of reasons:

   * It shows only IFF-ILBM format picture files. And it can handle all
     popular variants and formats.

   * Unlike many other IFF-ILBM viewer programs, this one was specifically
     written for graphics cards, using the CyberGraphX API (which is also
     supported by the Picasso96 software); it does not run on a plain Amiga.
     While this sounds like a disadvantage, it allows you to view HAM8
     pictures on an ECS Amiga.

   * This program supports colour cycling.

   * Unlike other picture viewers, this program will try to display all
     pictures in the correct aspect ratio. On a graphics card, every
     pixel is square, yet there are IFF-ILBM pictures which require
     pixels that are twice as wide as they are tall (or twice as tall
     as they are wide).

And of course, there are the control options this program offers and the
source code is included, too.


History
=======
1.12 (29.11.2005)
- Fixed a data structure alignment issue when compiling on PowerPC that
  prevented loading GraphiCraft pictures. [Reported by Alex Carmona]

1.11 (26.11.2005)
- Fixed the backwards cycling direction issue. As it turns out, the CRange
  structure contains a bitmask. [Reported by Alex Carmona]
- Now the initial state of the cycle counters is used and preserved.

1.10 (15.08.2005)
- Ported to OS4.
