As xasy
is written in the interactive scripting language
Python/TK
, it requires Python
(http://www.python.org), the Python Imaging Library
(http://www.pythonware.com/products/pil/), and the tkinter
package (included with sPython
under Microsoft Windows
) be
installed. Fedora Core Linux
users can either install
tkinter
with the command
yum install tkinteror manually install the
tkinter
, tix
, and tk
packages.
Pictures are deconstructed into the PNG image format, which
supports full alpha channel transparency. Under Microsoft
Windows
, this requires Python 2.5 (or 2.5.1)
and the
Python Imaging Library
:
http://www.python.org/ftp/python/2.5.1/python-2.5.1.msi
http://effbot.org/downloads/PIL-1.1.6.win32-py2.5.exe.On
UNIX
systems, place
http://effbot.org/downloads/Imaging-1.1.6.tar.gz in the
Asymptote
source directory, and type (as the root user):
tar -zxf Imaging-1.1.6.tar.gz cd Imaging-1.1.6 patch -p1 < ../patches/TkAlpha-Imaging-1.1.6.patch python setup.py install
Alternatively, xasy
can deconstruct pictures into the GIF
image format (not recommended as this is very slow), using white as the
transparent color. This requires the lines
import settings; xformat="gif";in the
Asymptote
configuration file (see configuration file),
along with the ImageMagick
(see convert) program.
