Open Image Viewer is a hardware accelerated blazingly fast open code c++20 compliant cross-platform application for accurately viewing and analyzing image files.

It provides accurate representation of the image being viewed, unlike the vast majority of the current viewers that shows the monitor color space data.

Emphasis on ergonomics and performance is thoroughly weighed to suit every type of user, the starting novice or the hardcore power user.

Currenlty there's virtually no GUI, keyboard key bindings is used for fast workflow, press F1 to list all keybindings.
