canvas-toBlob.js implements the standard HTML5 canvas.toBlob()
and
canvas.toBlobHD()
methods in browsers that do not natively support it. canvas-toBlob.js
requires Blob
support to function, which is not present in all browsers. Blob.js
is a cross-browser Blob
implementation that solves this.
canvas-toBlob.js has the same browser support as FileSaver.js.
