What Stipple Effect is

Stipple Effect is a pixel art editor for Windows, macOS, and Linux, designed for iterative game assets and other artwork. It includes animation timelines, onion skins, indexed-color tools, sprite-sheet export, and STIP, PNG, and GIF output. You can split sprite sheets into frames, stitch animations back into sheets, and edit while playback runs. Painting tools include two-color control, dither, blend, noise, shade, palettization, and script brushes. Automation scripts can perform most editor actions, including batch operations on open projects. Preview scripts transform project content for display, rerun after edits, and can turn their output into projects. A Visual Studio Code extension provides syntax highlighting for the DeltaScript language. The demo includes all features except saving and exporting. The editor requires Java 17 or later; the Windows installer includes it, while the cross-platform build needs a separate JRE. Projects are limited to 1920 by 1080 pixels. It is a one-time purchase through itch.io or Humble Bundle, with future updates included.
