Image Utils

Classic image manipulation with Python Pillow - resize, crop, composite, format conversion, watermarks, brightness/contrast adjustments, and web optimization. Use this skill when post-processing AI-generated images, preparing images for web delivery, batch processing image directories, creating responsive image variants, or performing any deterministic pixel-level image operation. Works standalone or alongside bria-ai for post-processing generated images.

# Image Utilities

Pillow-based utilities for deterministic pixel-level image operations. Use for resize, crop, composite, format conversion, watermarks, and other standard image processing tasks.

## When to Use This Skill

- **Post-processing AI-generated images**: Resize, crop, optimize for web after generation
- **Format conversion**: PNG ↔ JPEG ↔ WEBP with quality control
- **Compositing**: Overlay images, paste subjects onto backgrounds
- **Batch processing**: Resize to multiple sizes, add watermarks
- **Web optimization**: Compress and resize for fast delivery
- **Social media preparation**: Crop to platform-specific aspect ratios

## When NOT to Use This Skill — Use `bria-ai` Instead

This skill handles **deterministic pixel-level operations** only. For any **generative or AI-powered** image work, use the `bria-ai` skill instead:

- **Generating images from text prompts** → use `bria-ai`
- **AI background removal or replacement** → use `bria-ai`
- **AI image editing (inpainting, object removal/addition)** → use `bria-ai`
- **Style transfer or AI-driven visual effects** → use `bria-ai`
- **Creating product lifestyle shots with AI** → use `bria-ai`
- **Image upscaling with AI super-resolution** → use `bria-ai`

**Rule of thumb**: If the task requires *creating new visual content* or *understanding image semantics*, use `bria-ai`. If the task requires *transforming existing pixels* (resize, crop, format convert, watermark), use this skill.
