[Ssc-dev] Wrapping up Sprint 1: Obscura on the Android Market

[Andrew Senior]

OK. I'm working on the robustness of the Jpeg library - handling more
variants of JPEG/EXIF etc. (So I'm still happy to receive sample photos from
more devices)

I'll try to find some time to get the latest obscura code and play with it -
does it use the redaction library, currently?

It should be possible to implement all of the effects that you have in the
compressed domain, but they'll each take a bit of work. For the overlay
cases we would need to pass in a JPEG-encoded version of the overlay of the
right dimensions to fill the rectangle.
