The coordinates of the rectangle can be entered either via the widgets on the control panel, or as pick data (see below). Attempting to set X Min greater than X Max will result in X Min being set to X Max, and vice versa (similarly for Y). Since each dimension of the cropped lattice is always at least one, this means that a single row or column or point can be extracted from the lattice if required. In addition, rectangle coordinates which are outside the range of the coordinates of the input lattice are clamped to this range.
The cropping rectangle is snapped to the closest nodes of the input lattice at each of its corners.

The data lattice. It can be of any primitive type, and have any
number of data variables. The cropping rectangle is set to the
extent of the coordinates of the lattice whenever a new lattice
is passed to the module.

Input location. The left mouse button is used to update
the bottom left (X Min, Y Min) corner and the middle button
is used for the top right (X Max, Y Max) corner.
Port: X Min
Type: Text
The X coordinate of the bottom left corner of the rectangle, measured
in the same units as the coordinates of the input lattice.
Port: X Max
Type: Text
The X coordinate of the top right corner of the rectangle, measured
in the same units as the coordinates of the input lattice.
Port: Y Min
Type: Text
The Y coordinate of the bottom left corner of the rectangle, measured
in the same units as the coordinates of the input lattice.
Port: Y Max
Type: Text
The Y coordinate of the top right corner of the rectangle, measured
in the same units as the coordinates of the input lattice.
Port: Apply Crop
Type: Button
Applies the cropping rectangle and uses it to crop the
input lattice. No output lattice is produced until this button
is pressed.
Port: Undo Crop
Type: Button
Resets the cropping rectangle to the extent of the coordinates of
the input lattice.
Port: Color
Type: Text
Color string used to color the rectangle geometry. See
cxParamColorFloatGet(3E) for valid color names.
Port: Box
Type: Geometry
The geometry of the region.

Type: Lattice
Constraints: 2..-D.
uniform.
The output lattice. Its extent is determined by finding, in each
dimension, the nearest node to each corner of the cropping rectangle.
