About ArcBrush
ArcBrush is a node-based image editor for Windows, macOS and Linux. Images are built as a graph of nodes, so every step stays editable.Its Pixel Art node is a sprite, icon and tile editor inside that graph. It has layers, Pixel-Perfect tools, symmetry axes, seamless wrapping, Marquee, Lasso and Magic Wand selections, RGBA or Indexed canvases whose palette round-trips with Swatches, and a shading ink along palette ramps.
Other nodes can recolor, pack into atlases and batch export the result. Export Data writes CSV, JSON or text sprite tables.
It also has nodes for texture and material work, photo editing and compositing. It is free for personal use; commercial use needs a one-time Pro license.
