bbox of eps backend : test needed

Development matplotlib-devel
1

Hi,

I just committed a simple change that disables pstoeps in ps backend
when "xpdf" distiller is used. Without this, output bbox was incorrect
with "xpdf" distiller and usetex=False.

Getting the correct bbox with the ps backend is very tricky, and it'll
be appreciated if others help me test this.

Here is a simple test script (this needs to be run with most recent
svn version of matplotlib, and you need to able to use ustex=True!).
It will produce 6 eps files. Please check if any of the eps files have
incorrect bbox. And report which file has wrong bbox and your setup :
your OS, gs version number (output from "gs -v"), pdftops version
number (output from "pdftops -v"). It will be also good if you report
your setup even when everything is okay.

import matplotlib.pyplot as plt

plt.plot([1,2])

for distiller in ["False", "xpdf", "ghostscript"]:
    for usetex in ["True", "False"]:
        plt.rcParams["ps.usedistiller"]=distiller
        plt.rcParams["text.usetex"]=usetex

        plt.savefig("test_bbox_%s_%s.eps" % (distiller, usetex))

Evince shows a few of the eps files weirdly:

test_bbox_ghostscript_False.eps comes out as 8.5x11 inch while the other come out as 8x6 inches.
test_bbox_xpdf_False.eps is the correct size, but the graph was placed as if it was centered on a 8.5x11 page, thereby cutting off the bottom half of the graph.

The system:

Fedora 13
pdftops 0.12.4
ghostscript 8.71
evince 2.30.3 (using libspectre 0.2.4)

I will try out my Ubuntu system tonight.
