asymptote: GUI installation
11.1 GUI installation
=====================
As 'xasy' is written in the interactive scripting language 'Python/TK',
it requires 'Python' (<http://www.python.org>), the 'Pillow' fork of the
'Python Imaging Library',and the 'tkinter' package (included with
'Python' under 'Microsoft Windows'). 'Fedora Linux' users can either
install 'tkinter' and 'Pillow' with the commands
dnf install tkinter
dnf install tk-devel
dnf install python-pillow-tk
or manually install the 'tkinter', 'tix', 'tk', and 'tk-devel' packages.
Pictures are deconstructed into the PNG image format, which supports
full alpha channel transparency. Under 'Microsoft Windows', this
requires 'Python 2.7.4' or later and version '3.1.0' of the 'Pillow'
fork of the 'Python Imaging Library', available from
<http://pypi.python.org/pypi/Pillow>
