GSELNT(3NCARG) NCAR GRAPHICS GSELNT(3NCARG)

GSELNT (Select normalization transformation) - selects a predefined or user-defined transformation that maps world coordinates to normalized device coordinates.

CALL GSELNT (TRNUM)

#include <ncarg/gks.h>

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:

0
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.

1
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.

Online: set, gsup, gswn, gqclip, gsel_norm_tran
