Specify a multisegment closed polygon file that describes the inside area of the grid that should be rotated.
G | save | outgrid | outfile :: [Type => Str]
Output grid file name. Note that this is optional and to be used only when saving the result directly on disk. Otherwise, just use the G = grdrotater(….) form.
R | region | limits :: [Type => Str or list or GMTgrid|image] \(Arg = (xmin,xmax,ymin,ymax)\)
Specify the region of interest. Set to data minimum BoundinBox if not provided.
T | ages :: [Type => Str | Tuple]
Sets the desired reconstruction times. For a single time append the desired time. (http://docs.generic-mapping-tools.org/latest/grdrotater.html#t)
V | verbose :: [Type => Bool or Str] \(Arg = [level]\)
Select verbosity level, which will send progress reports to stderr.
b | binary :: [Type => Str]
d | nodata :: [Type => Str or Number] \(Arg = [i|o]nodata\)
Control how user-coded missing data values are translated to official NaN values in GMT.
Select grid interpolation mode by adding b for B-spline smoothing, c for bicubic interpolation, l for bilinear interpolation, or n for nearest-neighbor value.
