deepzoom_tile.py Issue

[Kathleen Sucipto]

Hi,

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

Process TileWorker:
Traceback (most recent call last):
  File "/usr/lib/python2.7/multiprocessing/process.py", line 258, in
_bootstrap
    self.run()
  File
"/usr/share/doc/python-openslide-examples/examples/deepzoom/deepzoom_tile.py",
line 66, in run
    tile = dz.get_tile(level, address)
  File "/usr/lib/python2.7/dist-packages/openslide/deepzoom.py", line 142,
in get_tile
    tile = self._osr.read_region(*args)
  File "/usr/lib/python2.7/dist-packages/openslide/__init__.py", line 219,
in read_region
    level, size[0], size[1])
  File "/usr/lib/python2.7/dist-packages/openslide/lowlevel.py", 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,

Kathleen
