What does this software do then ?
|
||
|
|
=================================
|
||
|
|
|
||
|
|
aview is an high quality ascii-art image(pnm) browser and
|
||
|
|
animation(fli/flc) player usefull especially with lynx browser.
|
||
|
|
|
||

What is PNM file format?
|
||
|
|
========================
|
||
|
|
|
||
|
|
PNM if an graphics format similiar to GIF, JPEG, PNG, TIFF and
|
||
|
|
others. Aview uses it because of its simplicity. Many free or shareware
|
||
|
|
conversion tools from other graphics format exist (ImageMagick, NetPBM
|
||
|
|
for UNIX, alchemy for DOS and others.) So you should use aview to
|
||
|
|
browse images in many graphics format. UNIX version has script that
|
||
|
|
does conversion automatically (using eighter NetPBM (preffered way)
|
||
|
|
or ImageMagic conversion program. FIFO is used to do not waste your
|
||
|
|
disc space so conversion is fully transparent. Under DOS and other
|
||
|
|
operating systems you probably need to do it yourself.
|
||
|
|
|
||
|
|
Usage
|
||
|
|
=====
|
||
|
|
|
||
|
|
UNIX:
|
||
|
|
asciiview [filenames] [options]
|
||
|
|
|
||
|
|
to browse any image format supported by NetPBM or ImageMagick. Use OTHERS
|
||
|
|
way if you don't have installed these tools
|
||
|
|
|
||
|
|
options should be listed using aview or aaflip program when used w/o
|
||
|
|
parameters
|
||
|
|
|
||
|
|
OTHERS:
|
||
|
|
aview [options] [filename]
|
||
|
|
|
||
|
|
To browse pbm pgm ppm or pnm image.
|
||
|
|
|
||
|
|
aaflip [options] [filename]
|
||
|
|
|
||
|
|
to browse fli or flc animation
|
||
|
|
|
||
|
|
Once aview is started use 'H' for help about keys.
|
||
|
|
|
||
|
|
How this all started
|
||
|
|
====================
|
||
|
|
|
||
|
|
Once upon a time we've (my friend Kamil and I) bought two old
|
||
|
|
Herculeses as secondary monitors. We didn't know for that time that our
|
||
|
|
Diamond Stealths 64 cards would become obsolete soon. The next day we
|
||
|
|
downloaded the logo of Linux Texas Users Group - nice silly penguin
|
||
|
|
looking like a cowboy! It was so exciting logo ... we decided that we
|
||
|
|
couldn't live without it and we wanted to see it at boot time as a logo
|
||
|
|
on our secondary monitors. There was a small problem - Hercules doesn't
|
||
|
|
support color graphics. So we decided to convert the penguin image to
|
||
|
|
ascii art using netpbm tools.
|
||
|
|
|
||
|
|
The output was very ugly because the converting algorithm was
|
||
|
|
absolutly stupid. During the night I designed a new convertor that
|
||
|
|
used a font bitmap to creat an aproximation table. The output wasn't
|
||
|
|
very good since the algorithm wasn't tuned so well. Many months this
|
||
|
|
small piece of code was waiting on my disc for the day "D". Meanwhile I
|
||
|
|
started a new project XaoS (a fractal zoomer) with my friend Thomas.
|
||
|
|
And then I got an idea: Ascii Art Mandelbrots! I was really impressed
|
||
|
|
by the result! XaoS was faster, portable and looking much better than
|
||
|
|
ever before. I found a new way to go ...

Three goals of AA-Project:
|
||
|
|
|
||
|
|
1. Port all important software (like Doom, Second Reality, X windows
|
||
|
|
etc..) on AA-lib.
|
||
|
|
|
||
|
|
2. Port AA-lib on all available platforms (mainly ZX-Spectrum and
|
||
|
|
Sharp).
|
||
|
|
|
||
|
|
3. Force IBM to start manufacturing MDA cards again.
|
||
|
|
|
||
|
|
AA-project was started by Jan Hubicka. In that times just a few
|
||
|
|
people knew about it. Then a new demo named BB has been relased to show
|
||
|
|
the power of AA-lib technology. Now the project is freely available and
|
||
|
|
anyone can help.
