Easily convert characters to a picture with aligned text.

Pure javascript, no native or external dependencies.

A text input "LS" could look like this:

Quickstart

It's simple.

npm i text-to-picture

With async/await.

const textToPicture = require('text-to-picture')
 
const result = await textToPicture.convert({
  text: 'LS'
})
 
const str = await result.getBase64()
 
console.log(str) // data:image/png;base64,iVBORw0KGgoA...
 
// useful for http servers
const buf = await result.getBuffer()
// http response object
response.send(buf) // <Buffer 89 50 4e 47 ...>

With promises.

const textToPicture = require('text-to-picture')
 
textToPicture.convert({
  text: 'LS'
}).then(result => {
  return result.getBase64()
}).then(str => {
  console.log(str) // data:image/png;base64,iVBORw0KGgoA...
}).catch(err => handle(err))
