text2png: text-to-png generator for Node.js

text2png('Create png image\nfrom multi-line text!');

Quick start

text2png depends on node-canvas. See node-canvas wiki on installing node-canvas.

$ npm install text2png

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

Option

text2png(text, option)

|param|default| |---|---| |text|(required)| |option.font|'30px sans-serif'| |option.textHeight|30| |option.textAlign|'left'| |option.color (or option.textColor)|'black'| |option.backgroundColor (or option.bgColor)|'transparent'| |option.lineSpacing|0| |option.strokeWidth|0| |option.strokeColor|'white'| |option.padding|0| |option.padding(Left|Top|Right|Bottom)|0| |option.borderWidth|0| |option.border(Left|Top|Right|Bottom)Width|0| |option.borderColor|'black'| |option.localFontPath|| |option.localFontName|| |option.output|'buffer'|

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

'canvas' returns node-canvas object.

If you want to use any custom fonts without installing, use localFontPath and localFontName property.

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

Command line interface

$ npm install -g text2png
$ text2png --help
$ text2png -t "Hello!" -o "output.png"

Example

text2png('Example\nText', {
  font: '80px Futura',
  color: 'teal',
  backgroundColor: 'linen',
  lineSpacing: 10,
  padding: 20
});

Enjoy!
