$ npm install text2png

var fs = require('fs');
var text2png = require('text2png');
fs.writeFileSync('out.png', text2png('Hello!', {color: 'blue'}));

option.color = '#000' | 'rgb(0, 0, 0)' | 'black' | ...

option.output = 'buffer' | 'stream' | 'dataURL' | 'canvas'

option.strokeWidth = 1 | 2 | ... A padding may have to be set to avoid cutoff of stroke

text2png('with custom fonts', {
  font: '50px Lobster',
  localFontPath: 'fonts/Lobstar-Regular.ttf',
  localFontName: 'Lobster'
});

Command line interface

$ npm install -g text2png

  font: '80px Futura',
  color: 'teal',
  backgroundColor: 'linen',
  lineSpacing: 10,
