rt_raster_coveredby()

rt_errorstate rt_raster_coveredby	(	rt_raster	rast1,
		int	nband1,
		rt_raster	rast2,
		int	nband2,
		int *	coveredby
	)

Return ES_ERROR if error occurred in function.

Parameter coveredby returns non-zero if rast1 is covered by rast2

Parameters

rast1	: the first raster whose band will be tested
nband1	: the 0-based band of raster rast1 to use if value is less than zero, bands are ignored. if nband1 gte zero, nband2 must be gte zero
rast2	: the second raster whose band will be tested
nband2	: the 0-based band of raster rast2 to use if value is less than zero, bands are ignored if nband2 gte zero, nband1 must be gte zero
coveredby	: non-zero value if rast1 is covered by rast2

Returns

ES_NONE if success, ES_ERROR if error
