 ## Open Image with Napari
 
-Open image data (e.g. RGB, gray, hyperspectral) with an interactive Napari viewer. If a gray image is opened, the image will be pseudocolored for better visualization.

+    - mode - 'native' or 'colorize'. If 'colorized' is selected gray images will be colorized.
     - show - if show = True, viewer is launched. False setting is useful for test purposes.
