  • {string} filename required
The image path
  • {function} callback(err, data) optional
Callback with image base64 data
/* promise */
base64Img.base64('path/demo.png').then(function(data) {});

/* callback */
base64Img.base64('path/demo.png', function(err, data) {});

.base64Sync(filename)

The api same as base64, but it's synchronous
var data = base64Img.base64Sync('path/demo.png');

.requestBase64(url, callback)

  • {string} url required
  • {function} callback(err, res, body) optional
Callback with http request
/* promise */
var url = 'http://../demo.png';

var url = 'http://../demo.png';
base64Img.requestBase64(url, function(err, res, data) {});

.img(data, destpath, name, callback)
