alvi (Alkor JPEG-Viewer) is a very special JPEG
viewer. It can handle large JPEGs with a very small need
for RAM. You can display JPEG-files with 1600x1200 pixels
on an 520 ST (512 KB RAM). The maximum size of
32767x32767 pixels require 2.5 MB RAM.
alvi should run on any ATARI TOS compatible computer. The
display of the current version is only monochrome.
||alvi is not to be copied and/or sold for
money. This specifically (but not exclusively)
includes distribution on CD-ROM or floppies for
any kind of a fee. Free distribution without any
fees is allowable.
Please register your copy of alvi. The registration is
free of charge. Just send me a postcard. (A nice view of
your hometown or a beautiful landscape should be the
registation. (Last updated 1998/01/13)

I don't need grayscale support, this is implemented
for 2 unregistered users! One single person was asking
for color support...
||I have a MEGA ST, and so 256 colors or 16
grayscales are not avialable to me. I can't
implement features without the corresponding
hardware to test.
alvi is still under development!
New features of the (unofficial) version 0.06beta are:
- 8 grayscales modus for 16 color resolutions (ST low, TT mid
and other). Note: This is a "quick hack"! (It won't work on other
video hardware than ST/TT/F030. There will be a workaround if I
get my graphic card working.)
- "Best match" option: alvi choose the
best shrinking factor so that a picture complete
fitt into a window without the need to scroll.
- It's now possible to move the viewing area of a picture by
clicking and holding the left mouse button on the viewable
area and moving the mouse around. The movement rate is
dynamically adapted. (You need to move the mouse half of the
size of the window to reach all edges of the picture.)
- The cursor keys, shift + cursor keys and Clr Home /
Shift + Clr Home keys are now attached to the corresponding
window redraw routines.
- The window name field shows now the filename and a part of the
access path of the picture.
- Error messages are passed to a special window.
- New 3D look (16 color resolution or better).
The proportions in ST low (320x200x16) looks a bit upset.
Reason: The system font is 8x8 pixels large (not 16x8 like
all other resolutions).
Use 640x480x16 instead or install an other system font!
- Some bugs fixed.
Project UFG was started in summer 1993. We (Matthias
Hentschel and I) were fascinated by some fractal
programs, but frustrated by the terrible handling of the
user interface of these programs. You can't interrupt the
calculation (or you will loose all datas), you can only
use one resolution (mostly ST low, 320x200x16), and the
ST is blocked while calculate the fractal. At the result
of this frustating situation project UFG was formed.
Note: All fractals on this page has been created with UFG,
saved as XIMG (256 colors), converted to GIF, and slightly
manipulated for the web (shrinked and blured,
finally saved as JPEG).
Some special features of UFG:
- GEM GUI
- Resolution independent.
UFG work in 2/16/256 colors, from 320x200 pixels
You can calculate a fractal in ST high and
display it later in any available resolution with
wide possibilities of manipulations.
- Fractals are automaticaly compressed by UFG.
- Interrupt/continue calculation at any time.
- Coprocessor support.
Speedup by factor 20 and more.
- Extended MultiTOS features:
- Calculate several fractals simultaneous.
- Computer not blocked while calculation.
