Hi Tim
Yes, mbtiles would be cool. I've decided to go with vrt/overview for now
because mbtiles need a very recent GDAL. But mbtiles could be an additional
option in future (especially interesting for mobile devices).
Yes true thanks!
I'll look into it soon,,,
ciao

Noticed a few issues with the save dialog
1) "format" drop-down is empty
2) cannot select a new file
3) segfault when saving to an existing file
4) It would be nice to have that action in the legend contextual menu,
like for vector layers.
It would be really awesome to save those tiles straight into an
mbtiles sqlite data store too - a nice way to turn an online resource
into a portable fast local copy.

That's great news!
Concerning raster saving - will there be a mechanism for compressing
files?
It would be great if default compression schemes could be chosen for
different file types, and an option at save time - sort of like image
editors.
I had trouble building it with external spatialite, could only get it
to compile with cmake -DWITH_INTERNAL_SPATIALITE=TRUE - does this
require a special version of spatialite?

Etienne

Hi devs
I'd like to announce the branch 'raster-pipes-2' in Radims repository
https://github.com/blazek/Quantum-GIS for testing.
Radim did a great job in refactoring the process of reading /
resampling /
reprojecting / displaying / modifying raster layers. Every step is now
a
subclass of QgsRasterInterface, with the advantage that several steps
can be
chained in a QgsRasterPipe. Like that, the raster functionality is
nicely
separated into different classes and it is easy to add/remove elements
in
the pipe. The iteration over the raster parts is controlled by
QgsRasterIterator (because for high-resolution prints or analysis on
large
datasets, it is impossible to keep everything in memory at once).
Please report any issue you find in the branch to the developer mailing
list.
Besides the changes in code architecture, there is also a new feature
in the
raster-pipes-2 branch. It is now possible to write through
QgsRasterDataProvider (currently only supported by the gdal provider).
There
is a 'save as...' function also for rasters now (though it is not 100%
complete at the moment). There is the option to save a raster in one
file or
in tiles (the tiles are then saved in one directory and vrt / pyramides
are
automatically created. Very usefull for saving the contents of a WMS
layer).
Regards,
Marco
