Coverage Maintainability Rating Quality Gate Status

A lightweight image viewer for a fast image preview. It has been developed to have the same viewer available for all major operating systems - Microsoft Windows 11, macos and GNU/Linux.

The main goal is to have a free of charge cross-platform viewer with a simple design and minimum functions that are commonly used.

  • Transformations
    • Flip (horizontal, vertical).
    • Rotation (clockwise and counterclockwise in 90° steps).
    • Zoom (in, out, original size, fit to window).
  • Metadata information.
  • Fullscreen or Window mode.
  • Custom background color.
  • Custom image border color.
  • Remembers recent files.
  • Supports Apple's high definition trackpad gestures.
