Details

Encountered image distortion after reading with slide.read_region(), is there any solutions?

[bgilbert]

There is no OpenSlide or OpenSlide Python version 3.7.3. Please double-check your OpenSlide version.

Is this a generic tiled TIFF image, or is it produced by a particular scanner vendor?

When I use python 3.6, this problem has been solved. Thank you for your reply.

Was this an observed problem when using python 3.7.3 as the interpreter then?

[super233]

Do you mean that the problem was not reported in openslide when runing with python 3.7.3, but oberved after the target file generated? @jaharkes

I was just curious because the original bug report mentioned openslide-python-3.7.3 which is something that doesn't exist. And then you closed it with a comment that when you use python-3.6 the problem is solved.

So I was trying to figure out if the original report was about python-3.7.3 instead.

Ooops, sorry! The original report was about python-3.7.3! I have updated the issue description.

It's possible that this is caused by a bug in old versions of pixman. Are you still seeing this issue?
