The Oswald character is Copyright Walt Disney, and, unfortunately, not in the
public domain. However, I believe that I can use this picture under the fair
use clause, for demonstrational purposes, especially in low-resolution, ASCII
format. If I am wrong, I will promptly remove it.
Installation
------------
Look in your system's package manager. I don't maintain Windows binaries
anymore.
Building
--------
If you want to compile from source, you need autotools and automake. You may
need to specify the path to jpeglib. I usually just do
autoreconf -vi
./configure --with-jpeg-prefix=/usr/local \
--with-curl-config=`which curl-config`
make -j
Before installing, you may want to check that jp2a works by running `src/jp2a`
on some `.jpg` files. The `check` target is currently broken, and won't help
you. When you're ready to install,
make -j install
jp2a depends on jpeglib. If configure can't automatically find it, specify with
./configure --with-jpeg-include=PATH --with-jpeg-lib=PATH
or you can just type the prefix
./configure --with-jpeg-prefix=/usr/local/
You can also compile jp2a with libcurl, so it can automatically download images
from the net:
./configure --enable-curl
This will look for `curl-config' in $PATH, but you can specify it directly with
--with-curl-config=PATH if you need to.
Windows
-------
You need a working jpeglib for Windows and set up include paths yourself.
You will need to manually type out a `config.h` file. Example:
WIN32
NDEBUG
_CONSOLE
PACKAGE_STRING=\"jp2a x.x.x-win32\"
PACKAGE_BUGREPORT=\"csl@csl.name\"
HAVE_STRING_H
HAVE_STDLIB_H
FEAT_CURL
HAVE_CURL_CURL_H
CURL_STATICLIB
FEAT_TERMLIB
You need to add jpeg.lib to the linker. If you want libcurl support, you need
that as well. It should be available from http://curl.haxx.se
