getregion

x_min, x_max, y_min, y_max, x_inc_or_z_min, y_inc_or_z_max = getregion(dataset; gridreg=false, sds=0, GMT=false)

Inquire the region extents of a file or GMTgrid, GMTimage, GMTdataset or GDAL dataset.

Options gridreg and sds are only for GDAL datasets. When input is a string (a file name) the default is to use GDAL and the region comes in ‘pixel registration’ by default. Use gridreg=true to force ‘grid registration’. Still for input as string, use GMT=true to force the result to be given by grdinfo. An unfortunate consequence of using either GMT or GDAL to inquire a file/object is that the 5th and 6th outputs (only 4 when input is a GMTdataset) have different contents. It will be either x_inc, y_inc when reading with GDAL, and z_min, z_max when reading with GMT.
