I want to switch among images with a fixed zoomed ration to compare image details more conveniently, especially in super-resolution (SR).

However, most existing image viewers do not have this feature. Therefore, I want to develop an image viewer called Handy Viewer to meet my requirements.

This project is still under construction, advice, bug report and development are welcome 😃.
