[ome-users] [bug] Opening Nifty (.nii) files fails on large images

[Christian Niedworok]

I have actually managed to find the culprit.

Line 151 of NiftiReader:

pixelFile.seek(pixelOffset + no * planeSize);

all of these variables are declared as int, causing the calculation to
be done in int-space, leading to an overflow, before being cast to long.
One solution is to change line 150 from

int planeSize = FormatTools.getPlaneSize(this);

to

long planeSize = FormatTools.getPlaneSize(this);


Cheers,
Christian
