Crop a subregion of a grid (GMTgrid) or a image (GMTimage). The subregion is specified with the limits or region keyword; the specified range must not exceed the range of the input. This function differs from grdcut in the sense that it doesn't call the GMT lib and works only on in-memory array (i.e., no disk files).


A grid or an image, depending on the input type, plus two 1x2 matrices with the indices of the cropped zone.


using GMT

G = GMT.peaks();
Gc = crop(G, region=(-2,2,-2,2));
