New description:
Importing `TikzPicture` class from my optional Sage package
[https://github.com/seblabbe/slabbe slabbe-0.2.spkg] into Sage.
One example:
{{{
sage: from sage.misc.tikzpicture import TikzPicture
sage: V =
[[1,0,1],[1,0,0],[1,1,0],[0,0,-1],[0,1,0],[-1,0,0],[0,1,1],[0,0,1],[0,-1,0]]
sage: P = Polyhedron(vertices=V).polar()
sage: s = P.projection().tikz([674,108,-731],112)
sage: t = TikzPicture(s)
sage: t.pdf()
}}}
Second example:
{{{
sage: g = graphs.PetersenGraph()
sage: %time _ = TikzPicture(latex(g), standalone_configs=["border=4mm"],
packages=['tkz-graph']).pdf()
CPU times: user 3.52 ms, sys: 12.7 ms, total: 16.2 ms
Wall time: 2.24 s
}}}
compared to using view (which crops the vertices and creates two pages pdf
on mac):
{{{
sage: %time view(g, tightpage=True)
CPU times: user 126 ms, sys: 85 ms, total: 211 ms
Wall time: 6.06 s
}}}
Also, if dot2tex and graphviz available:
{{{
sage: t = TikzPicture.from_graph(g, prog='dot') # optional: dot2tex
}}}
