File support [feature request]

Is it possible to add File support to methods instead of using canvas elements (as well as having a Blob binary output)? This would be very handy as most of us are getting the image to modify as a File object from a input[type=file]. This way this library will be the ultimate solution to image processing client side 😄

@damianobarbati Are you really suggesting that the only thing people would like to scale are images that came from the camera apps from iOS or Android devices?

What about PNGs? GIFs? What about non-pictures such as scanned text documents? In fact, I’d argue that using pica is more useful when scaling scanned text than it is with pictures (since the interpolation built into the browsers is so bad).

We use pica here: http://html5.snowbound.com/ The DOC and PDF files are rendered to SVG on the server (and therefore we don’t use pica on them), but the TIFF and JPEG files are scaled via pica.

https://github.com/nodeca/image-blob-reduce - this is pica wrapper for files. With predictable quality.
