NAME

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

SYNOPSIS

#include <ncarg/gks.h>

void gsel_norm_tran(Gint tran_num);

DESCRIPTION

tran_num
(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 gset_win and gset_vp.

USAGE

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

ACCESS

To use the GKS C-binding routines, load the ncarg_gks and ncarg_c libraries.
