canvas-cli

What problem does it solve?

This Skill solves the difficulty of generating custom 2D images, technical diagrams, and visual assets without requiring a graphical design application or complex programming setup. It allows users to create precise raster graphics through simple, human-readable text commands.

Core Features & Use Cases

• Text-Driven Image Generation: Create PNG images by writing simple script files or inline command strings that define canvas size, shapes, colors, and text.
• Image Composition & SVG Rendering: Composite existing PNG images with cropping and scaling, or render SVG vector graphics directly to raster output.
• Use Case: A developer can generate a system architecture diagram with grid backgrounds, rounded rectangles, and color-coded service modules by providing a short text script to an AI model.

Quick Start

Use the canvas-cli skill to create a 1080x200 promotional banner with a radial gradient background and centered text reading "Summer Sale", then export it as a PNG file.
