identicon-browserify
Identicon generator for Node.js and now the browser!
Difference
This fork allows you to use create identicons in node and the browser with browserify. This also has a breaking change in signature, which no longer returns a buffer but instead a data uri. To keep compatibility between both browser and node versions of canvas, toDataURL
is used instead to generate identicons.
There is also an added an extra option to set a different mime type other than PNG (for example: JPEG ('image/jpeg') or the newer WebP ('image/webp')). PNG is used by default and is guaranteed by spec, however extra mime types are generally supported depending on canvas implementation.
Installation
$ npm install identicon-browserify

Example
var identicon = require('identicon-browserify')
// Asynchronous API
identicon.generate({ id: 'ajido', size: 150, type: 'image/jpeg' }, function(err, uri) {
if (err) throw err;
var image = new Image
image.src = uri // if your canvas implementation supports JPEG creation, then this will likely contain a (data:image/jpeg) header.
})
// Synchronous API
var uri = identicon.generateSync({ id: 'ajido', size: 40 }) // generates PNG identicon by default
Asynchronous API
.gen
.generate(opts, callback)
{
opts: Object,
callback: Function
}
.gen
.generate(id, size, [mimetype], callback)
{
id: String,
size: Number,
mimeType: String,
callback: Function
}
Synchronous API
.genSync
.generateSync(opts)
{
opts: Object
}
.genSync
.generateSync(id, size, [mimeType])
{
id: String,
size: Number,
mimeType: String
}
Please note mimeType
is always optional. Defaults to PNG
format. See the example for more details.
