save_montage on OSX: hemisphere truncated when saving montage

[mattvan83]

Dear PySurfers,

I used pysurfer 0.10.dev0 on OSX computer and tried to save a dorsal view of both hemispheres using the following self contained example code:

b = Brain("fsaverage", "both", "white", cortex=None, background="black")
b.show_view("dor")
n = 163842
for hemi in ["lh", "rh"]:
    for colormap in ["Reds", "Blues"]:
        data = np.random.randn(n)
        b.add_data(data, min=0, max=1, thresh=0, colormap=colormap, colorbar=False, hemi=hemi)

This code gave me the correct following dorsal view:

However, whenever trying to save this view with the following code, one of the hemisphere is truncated in the image saved: b.save_montage(os.path.join(WD,"self.contained.example.png"), order=['dorsal'], orientation='v', border_size=15, colorbar=None, row=-1, col=-1)

Anyone would have an idea of this problem?

Is this a distinct issue from #282?

[mattvan83]

Not distinct but specific to OSX since the problème didn't appear on CentOS.

Moreover, #282 has been redirected to problem of overlap and conjunction maps, but the truncated view problem is different from these.

I'm going to close this and we can continue the discussion of the montage truncation on #282. It's very confusing to have multiple issues open describing the same problem.
