63 The r.region program allows the user to manage the boundaries of a
64 raster map. These boundaries can be set by the user directly and/or set
65 from a region definition file (stored under the windows directory in
66 the user's current mapset), a raster or vector map, or a 3dview file.
67
68 The align parameter allows to set the current resolution equal to that
69 of the named raster map, and align the boundaries to a row and column
70 edge in the named map. Alignment only moves the existing boundaries
71 outward to the edges of the next nearest cell in the named raster map
72 -- not to the named map's edges. To perform the latter function, use
73 the raster=name option.
74
76 After all updates have been applied, the raster map's resolution set‐
77 tings are recomputed from the boundaries and the number of rows and
78 columns in the raster map.
