It has been developed to have the same viewer available for all major operating systems - Microsoft Windows 11, macOS and GNU/Linux.\n\nThe main goal is to have a free of charge cross-platform viewer with a simple design and minimum functions that are commonly used.\n\n- Transformations\n  - Flip _(horizontal, vertical)._\n  - Rotation _(clockwise and counterclockwise in 90° steps)._\n  - Zoom _(in, out, original size, fit to window)._\n- Metadata information.\n- Fullscreen or Window mode.\n- Custom background color.\n- Custom image border color.\n- Remembers recent files.\n- Supports Apple's high definition trackpad gestures.\n\n\n---\n**Looking for translators**\n\n🗒 If you are a native speaker of the non-US-English language and would like to help localize this application, please, see this [guideline][7] on how to join [the localization team][8].\n\n---\n\n![Application screenshot](src/resource/readme/screenshot_2022-10-07_21-59-01.png?raw=true \"\")\n\nSupported image formats cover the very common formats as well as the rare ones. The viewer does not intentionally [demosaic][1] the RAW images, but only displays the embedded thumbnail.\n\n\n| FORMAT                   | DESCRIPTION
