rx

rx is an open-source pixel-art editor for Linux. It uses a modal structure that lets users move between operations and editing through keyboard-oriented interaction. The application is designed around a compact, command-oriented way of working rather than a large set of constantly visible controls.

Its limited-interface approach keeps fewer controls prominent on screen. This makes the workspace relevant to users who prefer focused editing and keyboard-driven interaction. The modal design is a defining part of how rx is used, connecting movement between tasks with its command-based operation.

As open-source software, rx can be used and examined according to the terms of its license. Its Linux availability makes it suitable for users seeking an open-source pixel-art editor on that operating system. In the MirrorNest catalog, it belongs to the Photo & Graphics category alongside software for creating or editing visual content.

MirrorNest mirrors the official build directly onto its own storage and scans it for malware before publishing. The catalog identifies the available download as an unofficial build by toto, rather than as an official release from the rx project. This places rx in MirrorNest as a Linux Photo & Graphics application distributed with that build designation.
