Hello,
I would like use r.mapcalculator in a PyQGIS processing script to change
values from one raster in another accordingly. I don't know how to call the
variables row and col, which are now read as simple strings in the
following code:
processing.runalg('grass:r.mapcalculator',{"amap": rlayer, "bmap":
emptylayer, "formula": "amap[row,col]=bmap[(%i+row*%i),(%i+col*%i)]"%
(offset,scale,offset,scale), "GRASS_REGION_PARAMETER": "%f,%f,%f,%f"%
(xmin, xmax, ymin, ymax), "outfile": bdry_resamp})
Does anyone know the correct syntax to use this? It would be fine to do it
manually calling the module from the processing toolbox in QGIS as well,
but then I would have to specify the 'formula' as well.
Thanks,
Sophie
