* dashes<br>
* linewidth<br>
* lines, rectangles, ellipses<br>
* clipping to a rectangle<br>
* output to RGBA and PNG<br>

<br>
TODO:<br>
<br>

<br>
INSTALLING<br>
<br>
REQUIREMENTs<br>
<br>
python2.2+<br>
Numeric 22+<br>
agg2 (see below)<br>
freetype 2<br>
libpng<br>
libz<br>
<br>
Install AGG2 (cut and paste below into xterm should work)<br>
<br>
wget <a href="http://www.antigrain.com/agg2.tar.gz">http://www.antigrain.com/agg2.tar.gz</a><br>
tar xvfz agg2.tar.gz<br>
cd agg2<br>
make<br>
<br>
(Optional) if you want to make the examples:<br>
cd examples/X11<br>
make<br>
<br>
Installing backend_agg<br>
<br>
<br>
Edit setup.py: change aggsrc to point to the agg2 src tree and<br>
replace if 0: with if 1: in the backend_agg section<br>
<br>
Then just do the usual thing: python setup.py build<br>
<br>
Please let me know if you encounter build problems, and tell me<br>
platform, gcc version, etc... Currently the paths in setupext.py<br>
assume as linux like filesystem (eg X11 include dir, location of<br>
libttf, etcc) so you may need to tweak these<br>
<br>
Using agg backend<br>
<br>
python somefile.py -dAgg<br>
<br>
or<br>
<br>
import matplotlib<br>
matplotlib.use('Agg')</tt></p>

<br>
segments is a sequence of ( line0, line1, line2), where linen =<br>

transform is used to Transform the lines<br>

clipbox is a xmin, ymin, width, height clip rect<br>
<br>
colors is a tuple of RGBA tuples<br>
<br>
linewidths is a tuple of linewidths<br>
*** really should be called 'dashes' not 'linestyle', since<br>
we call gc.set_dashes() not gc.set_linestyle() ***<br>
<br>
linestyle is an (offset, onoffseq) tuple or None,None for solid<br>

antialiseds is a tuple of ones or zeros indicating whether the<br>

offsets, if not None, is an Nx2 array of x,y offsets to<br>
translate the lines by after transform is used to transform<br>
the offset coords<br>
