๐Ÿ•ถ๏ธ A view of its user interface (v. 3.0.3, dark theme, on my Linux PC, in French) with several tabs open showing different screenshots of Linux games. The active tab is open on a screenshot of the "Gameplay Football" game. I chose this image because it allows me to illustrate the use of the โ€œMotion Blurโ€ filter and because I'm not good enough at drawing to show my work :). Nevertheless, I tested this tool and found it to be both simple and powerful. Excellent.

On the top right are the image layers (only one for now) and below that is the history (only one: โ€œOpen an imageโ€), both simple and practical. On the left are the drawing tools, and at the bottom are the color palette, image characteristics, and zoom. At the top, in the title bar, are the edit menus and menus.

๐Ÿ“š๏ธ Pinta is a lightweight, libre & multi-platform bitmap image editor inspired by Paint.NET, allowing you to draw and manipulate images in a simple but powerful way. It offers the classic drawing tools (freehand drawing, lines, rectangles, ellipses, ...), adjustment and effect tools (35 tools), a complete history (allowing you to go back in time), layer support (to separate and group elements of your image) and a flexible workspace (fixed and/or floating windows).
