Terminal Image Rendering

Images in the terminal — no file explorer needed.

VS Code 1.110+ supports the Kitty graphics protocol for rendering images directly in the integrated terminal. Enable with terminal.integrated.enableImages: true.

Quick Start

# Verify the setting is enabled
# Settings → terminal.integrated.enableImages → true

# Display an image using imgcat (if installed)
imgcat assets/banner.png

# Or use a Node.js script with kitty escape sequences
node -e "const fs=require('fs');const b=fs.readFileSync('assets/banner.png').toString('base64');process.stdout.write('\x1b_Gf=100,a=T;'+b+'\x1b\\\\')"

Supported Methods

Method	Platform	Notes
imgcat	macOS (iTerm2 protocol)	brew install imgcat or use VS Code's built-in support
Kitty escape sequences	All platforms	Native protocol, works in VS Code 1.110+
chafa	Linux/macOS	brew install chafa — converts images to terminal graphics
Node.js inline	All platforms	Read file, base64 encode, write Kitty escape sequence

Use Cases for the AI assistant

Preview Generated Banners

After running banner generation scripts, preview results without leaving the terminal:

node scripts/generate-readme-banners.js
# Then preview the output:
imgcat assets/banner-main.png

Display Architecture Diagrams

Render diagram visualizations inline during development:

node scripts/generate-diagram-visualizations.js
imgcat diagram-visualization/cognitive-architecture.png

Visual QA for Brand Assets

Quick-check brand assets without opening files:

# Check all banner variants
for f in assets/banner-*.png; do echo "=== $f ==="; imgcat "$f"; done

Avatar State Preview

View the AI assistant's cognitive state avatars during development:

imgcat assets/states/meditation.png
imgcat assets/states/debugging.png

Node.js Helper

For cross-platform terminal image display without external tools:

const fs = require('fs');
const path = require('path');

function displayInTerminal(imagePath) {
  const data = fs.readFileSync(imagePath);
  const base64 = data.toString('base64');
  // Kitty graphics protocol: transmit and display
  process.stdout.write(`\x1b_Gf=100,a=T;${base64}\x1b\\`);
  process.stdout.write('\n');
}

// Usage: node display.js assets/banner.png
const file = process.argv[2];
if (file && fs.existsSync(file)) {
  displayInTerminal(file);
} else {
  console.error('Usage: node display.js <image-path>');
}

Settings

Setting	Value	Purpose
terminal.integrated.enableImages	true	Enable Kitty graphics protocol
terminal.integrated.gpuAcceleration	on	Better rendering performance

Limitations

• File size: Large images (>10MB) may be slow to render
• Format: PNG, JPEG, GIF supported; SVG must be converted first
• Terminal width: Images scale to terminal width — wide terminals show more detail
• SSH remotes: May not work over SSH unless the remote terminal supports Kitty protocol
