[weekly report] week 8: Raw processing in F-Spot

[Ruben Vermeersch <ruben savanne be>]

Hi all,

as planned, I wrote a GObject based wrapper around libraw that exposes
the needed functionality. Having never written a GObject from scratch
before, this was quite challenging! After pulling out some hairs, I did
get it working though: libfspotraw was born.

Next up was creating bindings for this library: libfspotraw-sharp. I
refreshed my knowledge about GAPI, the bindings tool for C# (it turns
out I didn't have much knowledge about it ;-)). After quite a lot of
poking and learning stuff the hard way, this also worked.

This allowed me to write an F-Spot loader based on this library, which
can be hooked into the loader infrastructure. Behold! F-Spot is now
capable of loading RAW files at full quality using dcraw (in the form of
libraw). When you click on a RAW, it will instantly load the embedded
preview and will then start loading the full RAW in the background.

This is all still quite slow, something I plan on looking into the
coming week, as well as adding some way of informing the user that this
is happening. I'm also looking into how to extract 16 bit data (which is
not possible through GDK, due to the limitations of GdkPixbuf), which
will be needed for processing of the RAWs.

All code is in gitorious, in my clone (the libfspotraw branch).

As for the shortlog:
