The branch is merged. Enjoy (and report issues on the bugtracker).

Hi all
I think it would be a good move to merge the raster-pipes-2 branch
back to trunk. Ok, I know more instabilities, things to polish, etc.
But in trunk, it receives more attention and people are more motivated
to work on it.
Any objections?
Regards,
Marco

Ok this is a more general question then - which format(s) should
raster export support?
It should support any GDAL raster driver that supports write and that
is useable with the active dataset.
I was referring to tif only in terms of the default profiles I
mentioned.

One thing that would be really nice is to have
some default profiles:
- options for maximum read performance regardless of disk space
- options for minumum file size regardless of performance
- options for 'middle of the road' between the above two
would you have these options for all file types? it could get a
little
complex, but worth the effort. For now I am implementing 1 default
for
each driver, which can be defined by the user.
I was thinking just for tiff as I think it is the most generically
used.

I have granted you write access, please work directly in
raster-pipes-2.

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
It just occurred to me that it would be a great thing to
implement
this as a widget+class in QgisGui, so that it could be used
elsewhere
(e.g. gdaltools, sextante).
You mean as a reusable widget like the crs selector? Yes that
would be great!
Regards
Tim
Any way I can help?

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.

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
