A Claude Code plugin that generates raster images (PNG, JPEG, WebP) from natural language prompts using Python rendering engines - charts, banners, layouts, logos, data visualizations, and procedural art.
Describe what you want, and Rasterize picks the best engine, writes a Python script, runs it, and delivers the image.
| Engine | Best for | Examples |
|---|---|---|
| Pillow | Photo compositing, filters, pixel ops, gradients | Banners, thumbnails, backgrounds |
| Cairo | Vector-style graphics, anti-aliased shapes, procedural art | Logos, icons, badges, geometric art |
| Matplotlib | Statistical charts, scientific plots | Bar charts, line plots, heatmaps |
| Plotly | Rich dashboards, annotated data viz, 3D surfaces | Multi-panel dashboards, scatter plots |
| Playwright | HTML/CSS layouts, complex typography, UI mockups | Social cards, pricing tables, event invites |
git clone https://github.com/suxrobgm/rasterize.git

Rasterize uses pdm to manage a virtual environment with all rendering engines:
cd rasterize
python scripts/setup.pyThis will:
- Install pdm if not present (
python -m pip install pdm --user) - Create a
.venvand install all dependencies - Download Playwright's Chromium browser
# Graphics & Branding
/render Create a social media banner for a tech blog called "Code & Craft" — dark theme, gradient accent
# Data Visualization
/render Plot a bar chart of quarterly revenue: Q1=$42M, Q2=$58M, Q3=$35M, Q4=$71M
# Layouts & Cards
/render Design an event invitation card for "Tech Meetup 2026" with date, venue, and modern layout
# Backgrounds
/render Create a dark gradient hero background (1920x1080) with subtle geometric shapes
# YouTube Thumbnails
/render Generate a YouTube thumbnail with bold text "10 Tips for Python" on a vibrant background
# Dashboards
/render Generate a 4-panel dashboard image with a bar chart, line chart, pie chart, and heatmap| Prompt | Result |
|---|---|
| Social media banner for "Code & Craft" | |
| YouTube thumbnail "10 Tips for Python" |  |
| 4-panel dashboard with sample data |  |
| Event invitation card for "Tech Meetup 2026" |  |
| Dark gradient hero background |  |
- Project Structure — directory layout, key directories, and what each part does
- You describe the image you want in natural language
- Rasterize routes your request to the best engine using the routing table
- It reads the engine's reference doc for patterns and best practices
- It writes a self-contained Python generation script
- It runs the script via
pdm run pythonin the plugin's venv - The script and output image are saved in
generated/for iteration
The generation script is kept after delivery so you can ask for tweaks ("make the text bigger", "change the color") without regenerating from scratch.
Rasterize uses code-based rendering, not AI image generation models. This means:
- No photorealistic images - it cannot generate photos of people, nature, animals, or real-world scenes
- No AI art - diffusion/generative AI styles (Midjourney, DALL-E, Stable Diffusion) are not supported
- Stylized only - it can create geometric, flat, pixel art, and procedural representations, but not realistic ones
- SVG not supported - this plugin is specifically for raster output (PNG, JPEG, WebP)
AI image generation via external APIs (e.g. DALL-E, Stable Diffusion, Flux) may be added as a future engine.
