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