About

Stipple Effect is a pixel art editor that supports animation and scripting. It is designed to facilitate a variety of workflows and to encourage rapid, iterative creation of video game art assets and other types of artwork.

SE was made by a solo indie game developer with the needs and skill sets of other indie devs in mind. It is lightweight and simple to learn and use, yet allows for considerable depth and complexity. SE has a feature-rich scripting API that can be harnessed for the automation of otherwise tedious and repetitive tasks.

Scripting

Stipple Effect supports scripting for three different use cases: automation, custom previews and color transformation. It is highly recommended for users that want to get the most out of the program to read the API and familiarize themselves with its potential applications.

• API
• Example scripts

I have created a VS Code extension that provides syntax highlighting for Stipple Effect scripts.

External Dependencies
