Hi Etienne
Thanks for the feedback, very much appreciated. I've fixed these issues
in raster-pipes-2 branch now.
There are still a few things missing in raster saving:
- write colortable to output dataset
- format specific options (e.g. compression)
- dynamic populating of the format combo box (currently hardcoded to
geotiff)
- progress indication for tile based saving and possibility to cancel
Regards,
Marco

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.
regards,
Etienne

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
