How to open images in python

[manerotoni]

Hello,
I was wondering whether we should also cover different ways how to open images in python?
Today a student came with her own image (tif from olympus). This is pretty nice , but openIJtiff could not handle it. We were able to open the image with skimage.io.imread.

We are now teaching students to use openIJTiff which is very specific for the course (nice because of the metadata).

We should at least point towards other options that can help in their day to day live.

Also the warning issued by openIJTiff could contain such information. It should be more helpful than just "This module is intended to parse from ImageJ-created tiff files. This tiff file was apparently not created by ImageJ."
could it at least get the numpy array. For instance revert to skimage.io.imread?

May be change the message to you can try to open the image with .... I will try a fix.

In progress PR #574

@manerotoni there is a PR by @grinic for opening other images in python: #462

Honestly this would be a very good information for all of us, as opening images in python is not always trivial.
Not sure if this should be an extra module or additional information.

For the moment I would like to have a more instructive warning in OpenIJTiff and may be switch to skimage.io.imread if the tiff format looks different than expected.
