Performance Notes

Interpreter performance varies by image complexity

Large codel blocks improve visibility

Execution speed depends on DP traversal

Minimal memory footprint

Debugging slow for complex artworks

Security Notes

Runs locally in interpreters

Very low security risk

Image files cannot execute without interpreter

Untrusted images safe to load

Sandbox-friendly environment

Monitoring Analytics

Use debuggers to track DP path

Visualize stack changes

Check hue/brightness transitions

Animate execution for clarity

Interpret performance via codel traversal

Code Quality

Use consistent codel sizes

Maintain clean color regions

Avoid anti-aliasing

Group instruction blocks logically

Document DP logic externally

Frequently Asked Questions about Piet

What is Piet?
