Scroom is a generic viewer for viewing 2D data. Plugins can be added easily to support new file formats. Currently, there only is a plugin available for viewing large TIFF files (tested up to 60 gigapixel, 1bpp), so it is also fair to say that Scroom is a viewer for large TIFF files.

I ran into missing (dev) libs. see my run below.
Libtool library used but `LIBTOOL' is undefined
plugins/tiff/src/Makefile.am:3: The usual way to define `LIBTOOL' is to add `LT_INIT'
plugins/tiff/src/Makefile.am:3: to `configure.ac' and run `aclocal' and `autoconf' again.
plugins/tiff/src/Makefile.am:3: If `LT_INIT' is in `configure.ac', make sure
plugins/tiff/src/Makefile.am:3: its definition is in aclocal's search path.
autoreconf: automake failed with exit status: 1

To fix
Currently the gtk ui lock causes a big mess. Some functions are called with the lock held, some not, and some cannot be called with the lock held because they will attempt to acquire the lock themselves.
All in all, there currently is no pattern in what to expect where.
Some ideas:
computeBase() is called with lo==NULL, resulting in a segfault at
Scroom::Utils::Registration baseCache = lo->cache(tile);
I know that this may not be perceived as an issue, but: I was wondering what environment best to use in order to build a scroom executable for Windows.
When zooming in, show an unsharp preview, instead of nothing at all
When zooming out, show the original picture, zoomed out, surrounded by ...
Adding and removing printfs is becoming a real pain
Especially the tiled bitmap directory is touching 100Mb
Scroom currently uses a futures "proposal", which has an api that is not compatible with the final version. We should migrate to the final version, to ensure future compatibility

Hence this dummy issue, that I intend to never close. Whenever I plan on releasing, I'll move it to the next milestone, such that the current one has no open issues left and can be closed.
It's a bit of a cludge, but it should work
PluginManager was originally written to support dynamic loading and unloading of plugins. In practice, dynamically loading plugins will never happen, and neither will unloading of plugins.
Furthermore, PluginManager loads plugins as a background task, assuming that loading plugins takes a lot of time. In practice, this is not the case.
If CPU capacity allows, load several TiledBitmaps in parallel.
DataFetcher::operator()(), for example, schedules tasks for reducing tiles, as well as subsequent datafetching tasks. Currently, this is done right up to the point where scroom terminates. This results in several problems.
