SYNOPSIS

CALL GSELNT (TRNUM)

C-BINDING SYNOPSIS

#include <ncarg/gks.h>

void gsel_norm_tran(Gint tran_num);

DESCRIPTION

TRNUM: (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.

USAGE

When a normalization transformation is selected, all world coordinate arguments to GKS functions are transformed by it.

ACCESS

To use GKS routines, load the NCAR GKS-0A library ncarg_gks.
