Description (last modified by wmoore)
Found as part of https://github.com/openmicroscopy/openmicroscopy/pull/1342
image.getPrimaryPixels().getTile() is giving unexpected pixel values (different from getPlane() for the same region).
Needs test and investigation.
E.g. for an image similar to a FRAP DV image used in the PR above:
# get 2x2 tile at x=0, y=0
>>> p.getTile(0,0,0,tile=(0,0,2,2))
array([[30464, 30208],
[29952, 29952]], dtype=uint16)
# getPlane and crop to top left
>>> p.getPlane(0,0,0)[0:2, 0:2]
array([[119, 118],
[117, 117]], dtype=uint16)
# compare as strings (as used in gatewaytest/pixels.py)
>>> plane2 = p.getPlane()[0:2, 0:2]
>>> tile2 = p.getTile(0,0,0,tile=(0,0,2,2))
>>> str(plane2)
'[[119 118]\n [117 117]]'
>>> str(tile2)
'[[30464 30208]\n [29952 29952]]'
