As xasy
is written in the interactive scripting language
Python/TK
, it requires that both Python
and the
tkinter
package (included with Python
under
MSDOS
) be installed. Fedora Core
users can either install
tkinter
with the command
yum install tkinteror manually install the
tkinter
, tix
, and tk
packages.
By default, xasy
uses the GIF image format
with white as the transparent color. To overcome certain side-effects, support
for an alternative transparent image format, PNG, is also available.
To enable full alpha channel support for PNG images in the
Python Imaging Library (PIL) used by xasy
, 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
To configure Asymptote
to use PNG files for picture
deconstruction, these lines need to be in the Asymptote
configuration
file (see configuration file):
import settings; xformat="png";
