ncl_gselnt man page
GSELNT (Select normalization transformation) — selects a predefined or user-defined transformation that maps world coordinates to normalized device coordinates.
CALL GSELNT (TRNUM)
void gsel_norm_tran(Gint tran_num);
(Integer, Input) - A normalization transformation number. The number of available transformations is implementation specific. In the case of NCAR GKS-0A, two normalization transformations are provided:
Selects the identity transformation in which both the window and viewport have the range of 0. to 1. in both coordinate directions. This is the default.
Selects a normalization transformation in which the window and viewport have been defined by calls to GSWN and GSVP.
When a normalization transformation is selected, all world coordinate arguments to GKS functions are transformed by it.
To use GKS routines, load the NCAR GKS-0A library ncarg_gks.
