Open Source Linux Pixel Art Software

Aseprite is a program to create animated sprites. Sprites are composed of layers & frames as separated concepts. Support for color profiles and different color modes: RGBA, Indexed (palettes up to 256 colors), Grayscale. Animation facilities, with real-time preview and onion skinning. Copy & paste. Drag & drop. Resize palette. Palette entries with alpha value. Select color harmonies. Create light and shadows with the shading ink. Create perfect strokes for pixel-art. Avoid extreme pixel distortions when rotating tiny sprites. Create patterns repeating the image in a 3x3 grid. Create custom brushes for dithering. Composite layers to create color effects. Open or save a sequence of images. Create animations and save them as .gif files. Export your work to sprite sheets in .png and .json files. Recovery your sprites in case of crash. Integrate Aseprite in your assets pipeline with the command-line interface (CLI). Store several animations in one texture atlas.

LibreSprite is a free and open-source program for creating and animating your sprites. Sprites are composed of both layers & frames. Tiled drawing mode, useful to draw patterns and textures. Pixel precise tools like filled contour, polygon, shading mode, etc. Several file types are supported for your sprites and animations. LibreSprite originated as a fork of Aseprite, developed by David Capello. Aseprite used to be distributed under the GNU General Public License version 2, but was moved to a proprietary license on August 26th, 2016. This fork was made on the last commit covered by the GPL version 2 license and is now developed independently of Aseprite. This program is distributed under the GNU General Public License Version 2. As LibreSprite has a newly budding community, we need help building the infrastructure of our development, support, and news networks.

PyxleOS is an open source Java based pixel editor. Why is it special? Because it is written in Java, it is inherently cross platform. This means any computer running Java (JVM) can run PyxleOS! While it is currently in very early Alpha, PyxleOS hopes to compete with current goto pixel editors such as http://pyxeledit.com/ . Why the name PyxleOS? Pyxle(pixel) OS(open source).

This simple project aims to create a Libre Office calc model to use it as a pixel art canvas. Colors are applied by using numbers (from 0 to 16) and formating conditions (calling styles for cells).

Pixer is the easiest and most beautiful way to create pixel art in computer.

Image Maker is a small Java pixel-editor. Users can load .PNG files, edit them by-the-pixel + manipulate them in various ways, and save the edited image. Images are resized as you edit them to accomodate what you draw.

The goal of OpenPixel is to be an open source art program geared towards creating pixel art. It is written in Java and aims to be cross-platform and expandable via plug-ins.
