## What it is
A JavaScript library for generating autostereogram images (SIRDS, popularized as Magic Eye) in the browser using HTML5 Canvas. It renders stereograms from depth maps produced by pluggable DepthMappers such as text or canvas/image-based mappers.

## Use cases
- generate magic eye stereogram images in the browser
- convert text into a stereogram image
- turn a jpg or canvas image into a 3D stereogram
- create random-dot stereograms from a depth map
- embed stereogram generation in a web page

## When to choose
- you need client-side stereogram generation with no server dependency
- you want a small, focused library with pluggable depth-map sources like text or canvas

## When to avoid
- you need server-side or non-JavaScript stereogram rendering
- you need actively maintained software with a license and recent development
- you need general image editing rather than stereogram generation
