[Matplotlib-users] figure dpi output problem

[<jd...@eo...>]

I'm trying to get matplotlib to make a 600x300 png, but matplotlib won't
let me; it keeps making a 612x312 png instead.  Here's a sample script
that has the problem on my system:

figure(figsize=(6., 3.))
plot(arange(10))
savefig('test.png', dpi=100.)

If I set dpi to 50., it makes a 312x162 png.  It appears to be adding a 6
pixel border to the edge of all the pngs.  How do I get rid of it?

Windows XP SP2, Python 2.5, matplotlib 0.90.

I get a 600x300 png with that script, using the latest SVN.

Me too, on Linux, mpl 0.90dev3131. If it's adding a constant border of 6 on two
sides, can you tell mpl to export e.g. 588x288 (more hack than solution, though...)?
