Re: [matplotlib-devel] blurry images at native resolution with images.BboxImage: patch to fix

[Daniel H. <dh...@gm...>]

Ah yes, I forget :/  I was focused on images as being "pure" things that
should be displayed, and forgot about the image processing angle.

So would the solution be a keyword argument that tells imshow/BboxImage and
friends not to interpolate when at native resolution, which is set to the
current behavior as default?

If that's not an acceptable solution, I can just leave the patch in my own
personal code and not worry about any further...I thought that I was fixing
a bug there :)

I guess the main difference is whether the image is treated as sacred and
should be displayed perfectly when possible, versus the ability to modify
the picture on purpose via the interpolations, for whatever reason the user
wants.  Understandably, matplotlib has taken the latter approach, because
the context has always been (as far as I can tell from the examples)
displaying the pixels for a scientific purpose.  However, when you want to
display an image for a annotational type purpose, the former approach should
be taken, in my opinion.
