## What it is
CamanJS is a JavaScript library for manipulating images using the HTML5 canvas, offering a simple interface with filters like brightness, contrast, saturation, and vignette. It works both in the browser and in NodeJS, is library-independent, and extensible with plugins.

## Use cases
- apply image filters in the browser
- edit photos client-side with javascript
- adjust brightness and contrast of images on canvas
- add vignette or saturation effects to images
- manipulate images in nodejs
- declarative image editing via html attributes

## When to choose
- you need client-side image filtering without a server
- you want a simple, extensible canvas manipulation API
- you need compatibility with other JS libraries like jQuery

## When to avoid
- you need actively maintained software with recent fixes
- you require advanced photo editing like layers or masks
- you need modern build tooling or TypeScript support

## Facets
- artifact type: library
- maturity: abandoned
- function: image-processing, ui-components
- domain: image-processing, frontend, web-development
- platform: browser
- tags: html5-canvas, image-filters, photo-editing, coffeescript, client-side, nodejs, javascript
