## What it is
A WeChat mini-program canvas drawing component that generates shareable images from a single JSON configuration. It supports drawing text, images, rectangles, and saving the rendered result as a picture for sharing to WeChat Moments.

## Use cases
- generate share poster images in a WeChat mini-program
- draw text and images onto canvas with one JSON config
- create WeChat Moments share cards with QR codes
- render multiple share images in sequence
- add text styling like bold, underline, and ellipsis truncation on canvas
- save a composed canvas as an image to the phone album

## When to choose
- you are building a WeChat mini-program and need programmatic poster/share image generation
- you want a declarative JSON-driven drawing API instead of raw canvas code
- you need text features like line wrapping, ellipsis, strikethrough, underline, and bold
- you use mpvue or wepy and want a compatible port

## When to avoid
- you are not targeting WeChat mini-programs
- you need actively maintained software - the last release was in 2019
- you need complex layouts, gradients, or advanced canvas effects beyond its feature set
- your project uses a modern mini-program canvas API that the component does not support
