I just installed python-openslide 1.1.0 and ran the example code on a tiff image. Somehow it produces this error message:

Process TileWorker:
Traceback (most recent call last):
  File "/usr/lib/python2.7/multiprocessing/", line 258, in
line 66, in run
    tile = dz.get_tile(level, address)
  File "/usr/lib/python2.7/dist-packages/openslide/", line 142,
in get_tile
    tile = self._osr.read_region(*args)
  File "/usr/lib/python2.7/dist-packages/openslide/", line 219,
in read_region
    level, size[0], size[1])
  File "/usr/lib/python2.7/dist-packages/openslide/", line 217,
in read_region
    w, h))
OpenSlideError: negative width (259) or negative height (-32) not allowed

I tried it on a different computer and it works fine. Both of them use
Ubuntu 16.04 - 64 bit. Any idea why this issue occurred?

Thanks in advance!

Best regards,
