[Qgis-user] how qgis read a raster file

[frippe12573]

Hi everyone,

how qgis consider the coordinates of a raster file?
As center cell or as node (e.g. top left corner of the cell)?
It seems that in an .asc created outside QGIS (e.g. surfer) the coordinates
are referred to the top left corner of the cell.
The same .asc to be read and located at the same place have to be moved by
1/2 cell toward the top-left.
Does qgis refer the coordinates of all raster files as center cell?

Could anybody confirm?

Cheers,

Eugenio
