Hi Alexander,
thanks for your great work in this very useful plugin!
I was wondering if it is possible to add other (I think) interesting
functionalities to RasterCalc plugin:
- define a pixel resolution
- use a layer (vector or raster) as a mask
- use a layer (raster) as a region, in the sense of GRASS region, i.e.
using its pixel resolution, bounding box
thank again!

Hi Agustin,
thanks for your interest and feedback

1. Resulting raster is loaded in qgis as name.tif instead as name as usual.
2. If name.tif is selected for processing, you get a syntax error
3. If name.tif is renamed to name in the Layers list, the syntax error goes
away.
I'll fix all this issues tonight
4. Could you include a round() function?
5. In general, could you include all functions required to match
r.mapcalc functionality?
Ok, I'll try to include round() function ASAP.
About r.mapcalc functionality. We plan to improve plugin in future,
but unfortunatelly now I haven't much time (need to complete one project).
As result I can't say how quick I can add this stuff. I'll add your request to
the TODO and implement it later.
On Win XP (Standalone):
1.The plugin gets installed but cannot be run: "Couldn't import Python
module 'pyparsing'. Without it you won't be able to run RasterCalc"
Does this mean that RasterCalc can be run from the Osgeo4w version
only? If this is the case, this notice should be issued at installing
the plugin. And, most important, will we have RasterCalc working for
the Standalone version soon? (I'm interested on using it for a course).
RasterCalc should work with both QGIS, standalone and Osgeo4w if all
required modules are present. Required modules are: numpy, osgeo.gdal
(Python bindings to GDAL) and pyparsing.
As far as I know numpy and Python bindings to GDAL are already present
in standalone QGIS. So if you want to use RasterCalc with standalone
QGIS you only need to download and install pyparsing into QGIS python
folder.

Hope this helps. If you have any other questions feel free to email me.
