Applies the inverse of a contour's transform to the contour data.
apply_contour_transform_inverse([id])
-
id - an optional ChipsId structure containing values to modify
the currency state for the command, or a string to specify
the id of the contour to operate on.
The apply_contour_transform_inverse command applies the inverse of
the tranform, which is already associated with the contour. This
command is part of the advanced ChIPS module; refer to "ahelp chips"
for information on loading the module.
Transforms
are originally applied to contours either when the contour is created
or after the set_contour_transform
("ahelp set_contour_transform")
function has been called. If that transform has an inverse,
calling apply_contour_transform_inverse will apply the inverse
of that transform to the contour.
Calling apply_contour_tranform_transform multiple times will apply
the inverse of the transform to the data set multiple time.

chips> apply_contour_transform_inverse ()
Creates a contour with the params coordinate system
applied. The inverse of the transform is applied.
