[Qgis-developer] Re: [Quantum-GIS] Heatmap C++ Plugin (#82)

[Marco Hugentobler]

Hi Arunmozhi

Thank you very much for the heatmap plugin. I'm going to commit it to 
master if there are no objections (putting it into the raster menu).

 >I think a generic QgsFileWriter or QgsGDALFileWriter instead of (or 
along with) QgsGridFileWriter in the QGIS API would be a great feature

QgsGridFileWriter is used by the interpolation plugin for historical 
reason, I hope to change that soon. Much better is to use the GDAL API 
directly for raster creation (like in raster calculator or in raster 
terrain plugin).

Yes, a raster file writer class would also be a possibility. However, at 
the moment, I don't see much advantage over the creation with GDAL. 
Maybe the creation of GRASS rasters directly?

Regards,
Marco
