API

Note: All methods which take a callback, if omitted, will return a promise

.base64(filename[, callback])

Convert image file to image base64 data

• {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';
base64Img.requestBase64(url).then(function({ res, data }) {});

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

.img(data, destpath, name[, callback])

Convert image base64 data to image

• {string} data required
  Image base64 data
• {string} destpath required
  Dest path, if the destpath is root, pass empty string
• {string} name required
  The image's filename
• {function} callback(err, filepath) optional

/* promise */
base64Img
  .img('data:image/png;base64,...', 'dest', '1')
  .then(function(filepath) {});

base64Img.img('data:image/png;base64,...', 'dest', '1', function(
  err,
  filepath
) {});

.imgSync(data, destpath, name)

The api same as img, but it's synchronous
