[Matplotlib-users] trouble switching off smoothing in imshow()

[Anand S. <an...@st...>]

I ask having trouble getting imshow to plot e.g. a detector image showing pixels as little rectangular or square uniform color blocks - imshow seems to want to interpolate or smooth the image.
Using imshow("nearest") still produces a 'soft' image.

I have solved this problem earlier using figimage(), but that was a lot of work (I had to create a pixel-by-pixel array with all greyscale values set myself, and then I was working in pixel coordinates rather than my data coordinates).  Has anyone figured out how to get imshow to stop smoothing the image?  Using imshow(… interpolation='none'…) or imshow(… interpolation=None…) raise exceptions.

I found NonUniformImage too hard to figure out from the documentation.
