Open Source C++ 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.

PixelIt is an open-source firmware and hardware project designed to drive LED matrix displays using the ESP32 microcontroller. It's tailored for DIY enthusiasts and makers who want to create pixel art displays, show scrolling text, and integrate data from various APIs like weather or news. The project emphasizes customization and ease of use, allowing users to control displays via a web interface or REST API.

Float-ditherer is a tool that converts images into pure 1-bit images using a user specified palette tailored to convert images,textures and sprites using a float-based sampling method and float matrix. The software is meant to be lightweight and for power-users

Small and fast pixel editor.
