ISSUE TYPE

Feature Request

GEEQIE VERSION

1.5.1

SUMMARY

Add possibility to display numpy arrays files .npy and .npz

This formats are frequently used in image analyzis, datascience, etc.

Files with len(image.shape) == 2 display in grayscale, files with len(image.shape) == 3 and 3 or 4 components display as RGB and RGBA

The latest commit has an option to process a file externally and to view the resulting image within Geeqie. The feature is in Edit/Preferences/Advanced. The Help file gives examples of how to use this feature. Generating an image externally using Python will be slow, but might be useful in the meantime.

You will need to either compile from sources or use an AppImage: https://www.geeqie.org/AppImage/index.html

Do you have sample .npy and .npz files you can upload?

Current sources implement RGB only.
