int G_get_default_window

(

struct Cell_head *

window

)

read the default region

Reads the default region for the location into region. 3D values are set to defaults if not available in WIND file. An error message is printed and exit( ) is called if there is a problem reading the default region.

Parameters

region

Returns

int

int G_get_window

(

struct Cell_head *

window

)

read the database region

Reads the database region as stored in the WIND file in the user's current mapset into region. 3D values are set to defaults if not available in WIND file. An error message is printed and exit( ) is called if there is a problem reading the region. Note. GRASS applications that read or write raster maps should not use this routine since its use implies that the active module region will not be used. Programs that read or write raster map data (or vector data) can query the active module region using G_window_rows and G_window_cols..

Parameters

region

Returns

int
