invalid EPS figure in Mac OS X #3523
Description
I've upgraded to matplotlib 1.4.0 and am getting invalid EPS files (according to Preview) when I save figures that use
basemap (1.0.7). The same figure in PNG or PDF format works fine. I also saved a bar chart in EPS that worked.
I have verified that this happens in both OS X Mavericks and Mountain Lion. It doesn't matter whether I install using pip or homebrew. If I downgrade to matplotlib 1.3.1 it works fine.
Below is the code I was trying:
import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt
import numpy as np
from mpl_toolkits.basemap import Basemap
plt.figure()
m = Basemap(projection='npstere',lon_0=-270.,boundinglat=30.,round=True)
m.drawcoastlines(linewidth=1)
m.drawmapboundary(linewidth=1)
m.fillcontinents(color='silver')
m.drawmeridians(np.arange(-360,1,60))
m.drawparallels(np.arange(30,90,30))
plt.savefig('test.eps')
plt.savefig('test.pdf')
plt.savefig('test.png')[TAC edited for formatting]

If you are using python3 I think this is a duplicate of #3494 .

Can you post the corrupt file someplace?

I am back to this being a duplicate as the eps includes the line
Which I think should really be
and this is the conversion to
sixcausing a few more problems.Can you check if the patch at https://github.com/matplotlib/matplotlib/pull/3496.diff fixes the problem for you?

No dice. The EPS is the same, except for the %%CreationDate

ahh, I see, same problem,different place. How about with https://github.com/matplotlib/matplotlib/pull/3525.diff ? (I don't have a mac I can test on).

Still no change to the EPS.

Sorry, I was on a wild-goose chase, I was looking at the wrong
test.epsin my download directory....tacaswell commentedon Sep 16, 2014
The file has lines that look like this:
which the language reference manual seems to say is the syntax for putting in hex numbers (if I am reading it right) so I suspect something is going really wrong in the writer...

@bryan-woods Ok, lets try this again, have a look at https://github.com/matplotlib/matplotlib/pull/3526.diff
bryan-woods commentedon Sep 17, 2014
That's the winner!

Great! I would like to keep this issue open until that PR gets merged, it helps with tracking what still needs to be done.
