Painter is a JSON-driven canvas drawing library for WeChat mini programs (also usable in Node and HTML5) that renders images from a declarative 'palette' spec. It abstracts away the pain of the mini-program Canvas API, supporting text, images, rectangles, QR codes, gradients, shadows, rounded corners, and layout features.
Use cases
- generate shareable poster images in a wechat mini program
- draw images from templates on canvas
- create wechat moments share cards with qrcode
- render customizable image templates without touching canvas api
- generate posters with text, images and rounded corners
- dynamically edit and redraw canvas content via drag
When to choose
- you build WeChat mini programs and need programmatic image/poster generation
- you want declarative JSON templates instead of imperative canvas code
- you need features like gradients, shadows, borders, and QR codes in generated images
When to avoid
- you need server-side high-volume image rendering (node support is still TODO)
- your project is not a WeChat mini program or simple HTML5 canvas app
- you need complex shapes beyond text, image, and rectangle
