HandyView is a handy image viewer for convenient viewing and comparing. It is developed with PyQt5.

:sparkles: Features

• Switch among images with fixed zoom ration, which is useful when comparing image details. (Unfortunately, I cannot find such a image viewer and this is the initial motivation to develop HandyView).
• Various comparison modes.
• Show basic image information, e.g., image path, shape, size, color type, zoom ration, etc.
• Show the position and color in the current mouse cursor.
• Draw rectangles on images and show the start and end position.

:wrench: Usage

1. Download the pre-compiled executable zip file from the release page (Github | Gitee).
2. Unzip the file
3. Set HandyView as the default image viewer, so that you can double-click the image to open HandyView.

1. Download the handyviewer.dmg from the release page (Github | Gitee) and install.
2. If you fail to install the app, you may need to disable gatekeeper first. However, you should be aware of the risk of disabling gatekeeper.
3. Set handyviewer as the default image viewer (use `cmd+i), so that you can double-click the image to open handyviewer.

I used the early version of HandyView on Ubuntu. The current version is not tested on Ubuntu and may be out-of-date.
