## What it is
AlloyImage is a JavaScript image processing library built on HTML5 Canvas, offering multi-layer editing, 17 Photoshop-compatible blend modes, filters, and adjustments like hue, saturation, and curves. It provides a chainable API with Chinese/English parameter support and optional multithreaded processing.

## Use cases
- apply photo filters to images in the browser
- process user avatar uploads with style effects client-side
- blend image layers with Photoshop-style mix modes
- adjust brightness, contrast, hue, and curves of a photo in JavaScript
- add image styling to a mobile web app or PhoneGap app
- build an online photo editor web application

## When to choose
- you need client-side, dependency-free image effects on HTML5 Canvas
- you want Photoshop-like blend modes and layer-based editing in the browser
- you need a simple chainable API for photo adjustments in web or hybrid mobile apps

## When to avoid
- you need high-performance GPU-accelerated processing of very large images
- you require an actively maintained library with recent updates and strong license clarity
- you need server-side or native image processing
