Description From 2010-12-27 13:22:46 PST
Using the same semantics as toDataURL (image/png is the default output), add Blob getBlob([Optional] in DOMString contentType, [Optional] args...).

Currently, an image must be copied to a string using toDataURL, then to an array buffer using base64 decoding, before it can be run through createObjectURL. getBlob would reduce the number of operations.
