JP2A AmigaOS 4.0 Read Me
------------------------

jp2a is a small utility that converts JPG images to ASCII. It's written in C
and released under the GPL.

Important Note about the AmigaOS 4.0 port, it was not compiled with libcurl
support, so you can't convert images directly from the net. I'll implement
that in the future if LibCurl gets ported to clib2.



Example Usage:

jp2a --size=60x60 jp2a.jpg --output=jp2a.txt

gives you this;

COLORED IMAGES

You can also make coloured HTML images. They use CSS however, so currently we
can't display them
correctly with Amiga Browsers.

--html
Make ASCII output in strict XHTML 1.0, suitable for viewing with web browsers.
This is useful with big output dimensions, and you want to check the result with
a browser with small font.

--html-fill
When used with --html and --color, then color each output character's background
color.  For instance,
if you want to use fill-output on a light background, do

jp2a --size=60x60 --color --html --html-fill --background=light somefile.jpg
--output=dark.html

To do the same on a light background:

jp2a --size=60x60 --color --html --html-fill --background=dark somefile.jpg
--output=light.html

The default is to have fill disabled.

--html-fontsize=N
Set fontsize when using --html output.  Default is 4.

--output=...
Write ASCII output to given filename.  To explicitly specify standard output,
use --output=-.

-i --invert
Invert output image.  If you view a picture with white background, but you are
using
a display with light characters on a dark background, you shoudl invert the
image.

--red= ...
--green= ...
--blue= ...
When converting from RGB to grayscale, use the given weights to calculate
luminance.
These three floating point values must add up to exactly 1.0.
The default is red=0.2989, green=0.5866 and blue=0.1145.


SIZE

--size= WIDTHxHEIGHT
Set output dimension.


FINAL WORDS

For a deeper understanding of how this app works look in the source/man/ drawer
for a indepth usage guide
that unfortunately is in the unix man format.
