| | 180 | [[BR]] |
| | 181 | With the help of GRASS Python modules, It easy to pull chunks from raster data as Numpy array. A new rendering model (in-memory) can be added to wxGUI [[BR]] which can directly display a numpy array as wx.Image. This will obivously increase the performance of rendering layers because the overhead of [[BR]]reading and writing data to file (PNG adds a compression during packing and unpacking) can be saved. Also the extent based rendering [[BR]]will allow to read portion of raster image than whole dataset. Also a tile based technique can be added to this which improves the rendering [[BR]]performance further. |

| | 183 | Basically this will do what d.rast or generally speaking d.* modules do. I agree adding other modules such as d.legend etc is a massive work. But compared[[BR]] to dealing with large dataset I think its worth it.[[BR]]. |
